Changes to SharePoint Online pages running the classic user experience
Action Required by: February 14, 2018
Details: We're making some changes to SharePoint Online pages running the classic user experience. We're changing the default document mode of all classic pages to be Edge mode, instead of Internet Explorer (IE) 10 mode. This change does not apply to sites that are using custom theming, or sites that have the modern list experience disabled at the site or tenant level. This change will begin rolling out February 14th, and will complete by the end of February. For most users, this change will just increase performance and reliability of pages. However, some custom master pages or custom web parts may contain custom code that takes a dependency on the older IE10 document mode.
Additional Information: Display a classic SharePoint Online site in Internet Explorer 10 document mode
New process for updating Yammer profiles
Action Required by: February 15, 2018
Details: Beginning February 15, 2018, users will only be able to update Yammer user profiles using the 'Display Name' attribute of a user from Azure Active Directory, instead of the 'First Name' and 'Last Name' attributes. We are making this change to be consistent with the rest of Office 365.
Additional Information: Manage Yammer users across their life cycle from Office 365
Retirement of iOS Researcher App
Action Required by: March 30, 2018
Details: The iOS Research App is being retired. We will be removing the iOS Researcher App from the Apple Store on February 28, and users will no longer be able to use the app beginning March 30, 2018. Currently, you can access Researcher functionality in both Word and OneNote desktop applications. We recommend using the Word or OneNote desktop apps to access Researcher app functionality. Please update any internal documentation you may have, and direct users to use this functionality inside the Word and OneNote desktop apps.
Additional Information: Research your paper easily within Word
Postponed SharePoint Online Public Website Deletion
Action Required by: March 31, 2018
Details: If you postponed the deletion of your SharePoint Online Public Website, it will be deleted on March 31, 2018. Customers will see a banner at the top of their sites that states the following:
"Reminder: this site will soon be unavailable. Click Here to learn more."
The link in the banner points to the Knowledge Base article, included below in "Additional Information". The banner cannot be removed.
Additional Information: SharePoint Online Public Websites to be discontinued
Retirement of Office Mix Preview service
Action Required by: May 1, 2018
Details: We would like to let you know that we are retiring the Office Mix Preview service on May 1, 2018 and need you to take action to save your files. Please make sure to migrate all of your content to a storage location of your choice before the retirement date to avoid losing any of your data. Over time, we will be adding the best experiences of Office Mix across PowerPoint, Stream, and Forms to make it even easier for you to create and share interactive online videos.
If you have a qualifying account and would like us to migrate your existing mixes to Microsoft Stream, please visit the Office Mix migration page, sign in, and follow the prompts to automatically migrate your data. When the process completes, your mixes will be stored on Microsoft Stream as videos. You can continue to access Office Mix until May 1, 2018.
Mixes migrated to Stream will not include analytics data, quizzes or apps. However, over time these mixes will become interactive again. If you would like to save this content, you can download your mixes as PowerPoint files (.pptx), and your analytics data as Excel files (.xlsx) to save to your storage location of choice at any time before May 1, 2018.
We are bringing the best of the Office Mix add in directly into PowerPoint for Office 365 subscribers on Windows PC. Going forward, the new recording tab in PowerPoint will allow you to create a presentation that includes recorded slides, screen recordings, narrations, audio, ink, and videos. In the coming months, we’ll be connecting Forms for interactive quizzes and Stream to the recording tab to become the new publishing experience. In the meantime, you can manually export and upload these videos to Stream or another hosting site of your choice.
Additional Information: Migrate your content from Office Mix
Retirement of Outlook Groups app
Action Required by: May 1, 2018
Details: We’re pleased to announce that we’re focusing our efforts on expanding Groups functionality in the Outlook mobile app. Because of this new focus, we’ve decided to retire the standalone Outlook Groups app later this year. You can keep using it until May 1, 2018, but you can already find and collaborate with all your groups inside the Outlook mobile app. See Use groups in the Outlook mobile app to get started.
All of your existing group memberships and functionality will continue to work in Outlook on the web, Outlook 2016, Outlook 2016 for Mac, and any other Office application. Groups is an important part of making teamwork effortless inside Outlook and Office. These changes are part of both our continued efforts to refine Microsoft 365 as the universal toolkit for teamwork and the investments we’re making in Microsoft Teams and Yammer.
Additional Information: Outlook Groups app is retiring
Discontinuation of support for Session Border Controllers in Exchange Online Unified Messaging
Action Required by: July 2018
Details: In July 2018, we will no longer support the use of Session Border Controllers (SBC) to connect 3rd Party PBX systems to Exchange Online Unified Messaging (UM). We’re making this change to provide a higher quality of service for voicemail, using standard Exchange and Skype for Business protocols. Customers considering a new deployment of this scenario should be aware that they will have a little less than a year to complete one of the migrations below. Customers with existing deployments remain fully supported until July 2018, including moving voicemail-enabled mailboxes from Exchange on-premises and voicemail-enabling new mailboxes.
The following configurations are not affected by this change:
- Skype for Business Server (on-premises) connected to Exchange Online UM
- 3rd party voicemail solutions that deposit voicemail messages into Exchange Online mailboxes through APIs, rather than an SBC connection
- All forms of Exchange Server UM (on-premises)
There are several alternative solutions for impacted customers, all listed in the Exchange Team blog post announcing this change.
Additional Information: Microsoft Tech Community Discussion
We're removing Visio Web Access from SharePoint Online
Action Required by: September 30, 2018
Beginning September 30, 2018, users in your organization will only be able to view Visio diagrams in their browser, but not create or edit. Visio Online viewing is available to most Office 365 subscriptions.
Instead of using Visio Web Access (Visio Service) and its Web Part for SharePoint Online, we recommend using either:
- Visio Online and the Document Web Part [Document Web part instead of Visio Web part]
- iFrame in SharePoint Online for Visio Web Part [iFrame with Visio Online APIs instead of Visio Web Part with Visio Services JS APIs]
Additional Information: Migrate from Visio Web Access to Visio Online
Mandatory use of TLS 1.2 in Office 365
Action Required by: October 31, 2018
Details: As previously communicated in December 2017, to provide best-in-class encryption, and to ensure our service is more secure by default, we are moving all of our online services to Transport Layer Security (TLS) 1.2+. In the previous communications, we had indicated that we would be removing support for TLS versions less than 1.2 from our online services, beginning March 1, 2018. After receiving valuable feedback from administrators, we have decided to extend the deadline for upgrading to TLS 1.2 or later to October 31, 2018.
As of October 31, 2018, Microsoft Office 365 will no longer support TLS 1.0 and 1.1. By October 31, 2018, all client-server and browser-server combinations should use TLS version 1.2 (or a later version) to ensure connection without issues to Office 365 services. This may require updates to certain client-server and browser-server combinations.
If you do not update to TLS version 1.2 (or later) by October 31, 2018, you may experience issues when connecting to Office 365. If you experience an issue related to the use of an old TLS version after October 31, 2018, you will be required to update to TLS 1.2 as part of the resolution.
Although current analysis of connections to Microsoft Online services shows that very few customers still use TLS 1.0 and 1.1, we are providing notice of this change so that you can update any affected clients or servers as necessary before support for TLS 1.0 and 1.1 is disabled. If you are using any on-premises infrastructure for hybrid scenarios or Active Directory Federation Services, make sure that these infrastructures can support both inbound and outbound connections that use TLS 1.2.
Note: Using TLS 1.2 with Office 365 does not mean you must have TLS 1.0/1.1 disabled in your environments by October 31, 2018. If parts of your environment require the use of TLS 1.0 and 1.1 on or after October 31, 2018, you can leave the older protocol versions enabled. However, TLS 1.2 will have to be enabled and used for communication with Office 365 to avoid any interruption in service.
Additional Information: Preparing for the mandatory use of TLS 1.2 in Office 365
Yammer notes to Word Online conversion
Action Required by: January 26, 2018
Details: ***To give you and your users more time to save and store your existing Yammer notes, and to prepare for the pending migration, we have delayed the migration start date for conversion of Yammer notes to Word Online documents from December 8th, 2017 to January 26, 2018.***
Starting January 26, 2018, we will convert Yammer notes into Word Online documents. This function is currently on the top navigation bar in groups and allows users to create notes in Yammer. This will also allow us to provide a better service as we focus more on integrating with the Office 365 suite. Existing notes will be converted into files for now, as we plan to have more integration with SharePoint Online in the future. Only the last published version will be kept; all previous versions will be lost.
The migration will occur between January 27th - 29th. During this time users will have read-only access to their notes. After January 30th, Yammer notes will no longer be available and all your notes will be accessible as Word Online documents in your Yammer files. Please save any unpublished drafts and make sure to save any previous versions you wish to keep as we will only migrate the last published version. We strongly suggest communicating to your users about the conversion and to save any unpublished drafts. If your networks have files disabled please make sure to save a copy on your computer.
Additional Information: Converting Yammer notes into Word Online documents
