While the cloud offers real benefits in productivity, security, and total cost of ownership, we recognize that each customer is at a different point in their adoption of cloud services. Office 2019 is a valuable upgrade for customers who feel that they need to keep some or all of their apps and servers on-premises. As such, we are committed to another on-premises release in the future. However, we will be investing in and adding new capabilities to Office 365 regularly, including innovations in artificial intelligence (AI), collaboration, and security.

 

Office 2019 Server Previews are ready for Commercial customers

Note: October 2018 – Both Office 2019 and the Office 2019 Servers are now available. Learn more about Office 2019 here; learn more about Office 2019 Servers here.

 

Today we’re pleased to announce the commercial previews of Exchange Server 2019, Skype for Business Server 2019, SharePoint Server 2019, and Project Server 2019. This announcement wraps up our set of commercial previews for Office 2019, which included Office 2019 for Windows and Office 2019 for Mac earlier this year.  With this announcement, we’re well positioned to ship Office 2019, the next perpetual update to Office, in the next few months. 

 

Office 365 delivers the most productive and most secure Office experience – with the lowest total cost of ownership for deployment and management.  But for customers who aren’t yet ready to move to the cloud, Office 2019 provides an update to the perpetual apps and servers.

Exchange Server 2019
Exchange Server 2019 will support Windows 2019 Server core and allow customers to run Exchange on the most secure Windows operating system to date.  In addition, this release will include new and improved search powered by Bing and improved calendaring with features like Do Not Forward and Simplified Calendar Sharing.

Getting the best connectivity and performance in Office 365

Getting the best connectivity and performance in Office 365

Traditional enterprise networks are designed primarily to provide users access to applications and data hosted in company operated datacenters. A secondary use has been as a gateway for access to the Internet for communications and web browsing. In this model, there is minimal or no network security between users and the company operated datacenters, and a substantial security perimeter between users and the Internet with many network devices such as firewalls, anti-virus scanners, data loss prevention, and intrusion detection devices.

Because of the large network security stack, Internet connectivity for branch offices is commonly centralized and backhauled over the customer’s wide area network (WAN). This model worked well for secure access from users within the office to corporate on-premises apps such as email and document sharing where bandwidth could be assured, and minimal network security within the WAN meant network traffic was not impeded.

fig-1-png.pngTraditional enterprise network backhauling Internet bound traffic over its WAN

As enterprise adoption and reliance on SaaS apps like Office 365 continues to grow, and as employees work from more varied locations, the old methods of backhauling traffic to a central location for inspection creates latency and leads to a poor end user experience. The shift from accessing enterprise applications in a customer operated central datacenter to Office 365, and the differences in traffic patterns, performance requirements, and endpoint security needs to be acknowledged and planned differently when compared with simple Internet communications and web browsing research connectivity.

 

The Microsoft global network and Office 365

The Microsoft global network is one of the largest network backbones in the world consisting of high bandwidth links that have minimal network congestion, with thousands of miles of privately owned dark fiber, multi-terabit network connections between datacentres, and application front doors servers spread around the world. Over 100 public Internet peering interconnection locations on this network makes it easy for all users, regardless of location, to connect into the network using the Internet and access services such as Office 365, Azure, Xbox, Bing, Skype, Hotmail and more.

Microsoft continues to invest in the network, the geographical locations of the application front doors, public peering partnerships with ISP’s, and traffic backhauling capabilities. This allows user network traffic to enter the Microsoft global network very close to the user, and then the traffic is backhauled at Microsoft’s cost over high bandwidth lines within the network to the location where the user’s data is stored.

Office 365 connectivity principles

Microsoft recommends using the Internet and a simple network design for optimal connectivity and performance in Office 365. A key goal in the network design should be reducing the round-trip time (RTT) from your network into the Microsoft global network and ensure that the network traffic is not hair pinned or centralized to specific locations. Use the Office 365 connectivity principles to manage your traffic and get the best performance when connecting to Office 365.

 

1. Identify and differentiate Office 365 traffic using Microsoft published endpoints

fig-3-png.pngOffice 365 URLs and IP addresses aka.ms/O365IPAs a SaaS application Office 365 has a large number URL’s and IP Addresses representing Office 365 service front end servers. We refer to these URL’s and IP addresses as endpoints and customers can use them to identify specific network traffic that is destined for Office 365.

Identifying Office 365 network traffic is the first step in being able to differentiate that traffic from generic Internet-bound network traffic. Microsoft publishes the Office 365 endpoints and guidance on how best to use this data. An Office 365 administrator can use a script to fetch the endpoint details and apply it to a perimeter firewall and other network devices. This will ensure that traffic bound for Office 365 is identified, treated appropriately and managed differently to network traffic bound for generic and often unknown Internet web sites that employees may browse. See the Office 365 endpoint categories and Office 365 IP Address and URL web service to automate endpoint management.

 

2. Egress Office 365 data connections as close to the user as practical with matching DNS resolutionfig-4-png.pngLocal Internet egress into Microsoft’s networkMany enterprise WANs are designed to backhaul network traffic to a central company head office for processing before network egress to the Internet. Because Office 365 runs on Microsoft’s large global network that includes many front end servers around the world, there will often be a network connection and front end server close to the user’s location.

When compared to backhauling data across the corporate WAN, the user is most likely going to get better performance by egressing Office 365 network traffic to the Internet close to their location where it can be connected to Microsoft’s global network. Additionally, many Office 365 applications use DNS requests to determine the user’s geographic location. If the users DNS lookups are not done at the same point as the network egress the user may be directed to a distant Office 365 front end server.

By providing users with local Internet egress and local DNS resolution their network traffic destined for Office 365 can connect to Microsoft’s global network and Office 365 front end servers as close as possible to the user. Shortening the network path to Microsoft’s global network and to Office 365 front end servers in this way should be expected to improve connectivity performance and the end user experience in Office 365.

 

3. Avoid network hairpins and optimize connectivity directly into the nearest entry point into Microsoft’s global network
fig-5-png.pngEnterprise network hairpinning Office 365 bound Internet traffic
Microsoft is continuously working on reducing the distance between users and Office 365 endpoints, driving down latency and improving end user experience. There are two types of network route hairpin that may occur in connecting users to Office 365. These network hairpins greatly lengthen the network path between a user and Microsoft’s global network, and this increases network latency and reduces performance of Office 365.

As discussed, the second type can result from a cloud based network security infrastructure device. If the network device vendor has limited hosting locations and directs a user to a specific one that is distant from them they may create a hairpin route where network traffic goes from the user to the distant network device and back to an Office 365 front end server that is near the user. This can be avoided by asking cloud based network security vendors about the specific locations of their hosting and being critical of the network paths that this creates that may be different to the direct route to Office 365 endpoints on Microsoft’s global network.

The first type results from misaligned network egress and DNS lookups for a user. This can result in the user being directed to an Office 365 front end server that is close to them, but via a distant corporate egress location at a head office. This can be avoided by local egress and local DNS as outlined in the principle above.

 

4. Assess bypassing proxies, traffic inspection devices and duplicate security which is available in Office 365fig-6-png.pngBypassing additional security for Office 365

Generic Internet web browsing traffic to unknown Internet sites can have substantial security risk and most enterprises implement network security, monitoring, and traffic evaluation technology at their Internet egress locations. Network security technology includes proxy servers, inline SSL break and inspect of network traffic, network layer based data loss prevention, and more. Network security devices is a strongly growing industry. Unfortunately, whilst all this equipment reduces the enterprise risk of Internet connectivity, it also increases the cost and resources required for Internet connectivity, and it reduces the performance for network connections.

Office 365 servers are all hosted in Microsoft datacenters and Microsoft is very transparent about datacenter security, operational security and risk reduction around those servers and the network endpoints that they represent. These security details can be found in the Microsoft Trust Center. Office 365 also has many other methods available for reducing that network security risk including the built-in security features in Office 365 such as, Data Loss Prevention, Anti-Virus, Multi-Factor Authentication, Customer Lock Box, Advanced Threat Protection, Office 365 Threat Intelligence, Office 365 Secure Score, Exchange Online Protection, Network DDOS Security, and other many other security features.

Enterprise customers should review these risk reduction methods specifically for Office 365 bound traffic and use the Office 365 in-built security features to reduce the reliance on intrusive, performance impacting, and expensive network layer security technologies for network traffic that is identified as Office 365.

You’re about to get even more from your Office 365 Home or Personal subscription!

Today I’m pleased to share three exciting changes to Office 365 consumer subscriptions.  

 

Office on all your devices

The Office 365 Home and Office 365 Personal subscriptions currently include device install limits. Home limits subscribers to 10 devices in total (across five users) and Personal limits subscribers to one PC or Mac and one tablet.  Starting October 2, subscribers can install Office on an unlimited number of devices—and be signed into their accounts on up to five of those devices at the same time. 

 

Six licenses rather than five

The Office 365 Home subscription is already an incredible deal. For just $99.99 a year, five people can get their own licenses to Word, Excel, PowerPoint, Outlook, and OneNote—plus 1 TB of OneDrive cloud storage and other valuable apps and services. Starting October 2, we’re increasing the number of licenses in a Home subscription from 5 to 6. That’s right: we’re adding an additional person to the subscription with no change in price. To be clear, that’s 6 people with their own license and 1 TB of OneDrive cloud storage each—for a total of 6 TB. We’re also integrating the Home subscription more deeply into the Microsoft family service, so your subscription will automatically be shared with the people you’ve set up as members of your family.  

 

Everything you need in one place

Since launching the Office 365 consumer subscriptions in 2014, Office.com/MyAccount has been the starting point for all account management. We’re pleased to announce that you can now manage your Office 365 subscription directly on the Microsoft Account portal. —the single place to manage all your Microsoft subscriptions, redeem your Microsoft Rewards, and access other Microsoft benefits.

Announcing: Office 365 endpoint categories and Office 365 IP Address and URL web service

[Originally published for the preview on 4/2/2018 and updated on 7/6/2018. Updated for GA on 9/5/2018]

 

Announcing: The IP Address and URL web services are generally available from 5th September, 2018.

 

Microsoft recently published a set of connectivity principles for Office 365 which provides concise guidance on the recommended ways of achieving optimal performance and connectivity to Office 365. The first of these principles is to Identify and differentiate Office 365 network traffic using Microsoft published endpoints. Endpoints include IP Addresses and URLs that are used to connect to Office 365.

 

The primary benefits of using these web services are that they share the endpoint categories which significantly simplify network perimeter configuration, they are fully automated including automated validation testing them, they can be loaded directly into network devices, and they help automate change management to avoid change related outages. The endpoint categories identify a vital few key network endpoints in the Optimize and Allow categories for Office 365 for which we recommend direct Internet egress.

 

We use web services because they are easier for customers scripts and network devices to call than web pages. Specific scenarios where you might need this data include:

  1. Updating your perimeter firewall to allow Office 365 network connectivity.
  2. Updating your enterprise proxy server to allow connectivity to Office 365 URLs.
  3. Edit PAC files on your users computers to bypass proxy servers.
  4. Bypassing an SSL decrypting network device for Office 365 network traffic.
  5. Bypassing a CASB service for Office 365 network traffic.
  6. Selecting endpoints for bypassing proxy servers and routing for direct internet access at a branch office user location.

These web services directly offer Office 365 IP Address and URL data in JSON, and CSV format for all five Office 365 service instances including Office 365 worldwide commercial, Office 365 operated by 21 Vianet, Office 365 Germany, Office 365 U.S. Government DoD, and Office 365 U.S. Government GCC High. We also generate HTML pages from the data and RSS feeds are available from the web services to help with change notification.

Here’s a few quick links to the web services you can access right in a web browser. These links are provided for the worldwide Office 365 commercial instance as examples only.

 

The current XML file and the old RSS feed will be available until October 2nd, 2018. If you have automation that uses the XML format, you should update that to use the JSON format data. If you are using the old RSS feed you should either move to the new RSS feed, or use the sample Microsoft Flow we have published for getting emails on changes. Developer usage documentation for the IP Address and URL web services are detailed in Managing Office 365 Endpoints – Web Service.

 

The web services include three categories for Office 365 network endpoints as attributes of this data which can be used to simplify management of perimeter network devices:

  • Optimize for a small number of endpoints that require low latency unimpeded connectivity which should bypass proxy servers, network SSL break and inspect devices, and network hairpins. Direct Internet access, such as with SDWAN, is recommended for these endpoints.
  • Allow for a larger number of endpoints that benefit from low latency unimpeded connectivity but do not require it. It is required to bypass SSL break and inspect on these endpoints and to avoid proxy authentication. Although not expected to cause failures, we also recommend bypassing proxy servers entirely, network hairpins, and other network intermediary devices on these endpoints. Good connectivity to these endpoints is required for Office 365 to operate normally.
  • Default for other Office 365 endpoints which can be directed to the default internet egress location for the company WAN.

Use of these categories, how they simplify connectivity to Office 365, and what actions you can take to make use of them is detailed in Office 365 Network Connectivity Principles.

 

The web services and data contained in it are supported by Microsoft. However, you do not need to connect to these web services in order to use Office 365. Keep a local copy of the data and just call them again to check for changes. If you are ever unable to connect to the web services, just use the data you have previously downloaded. When a change is notified, you should have 30 days to make updates.
