Blocking Flash, Shockwave and Silverlight controls in Office 365 Semi-Annual Channel
Effective: January 2019
Details: We are announcing an upcoming change to Office that blocks activation of Flash, Shockwave and Silverlight controls within Office. We are taking this step based on the following factors:
- Use of some of these controls in exploit campaigns to target end users of Office
- Low observed use of these controls within Office
- Upcoming end of support for some of these components (Flash / Silverlight)
Note: This change will not apply to Office 2016, Office 2013 or Office 2010. This change only applies to Office 365 subscription clients in the Semi-Annual Channel and is targeted to take effect in January 2019.
Azure AD credentials will be required for Yammer Enterprise log in
Effective: January 31, 2019
Details: Starting January 31, 2019, Yammer Enterprise users that try to log in using legacy Yammer credentials instead of an Azure Active Directory (AAD) account will be redirected to a new sign up flow and will be asked to create a new password. After completing the required steps, an AAD account with no Office 365 licenses will be automatically created for the user. This process is called self-service signup.
- After changing their password, these users will be able to access your Yammer network, and will have access to all their groups and data. After the AAD account is created for a user, admins can manage the user from the Office 365 admin center.
- After the AAD account is created for a user, admins can manage the user from the Office 365 admin center.
OneDrive retiring support for Mac OS X 10.10 and 10.11
Effective: February 1, 2019
Details: The OneDrive engineering team is committed to bringing you the best, most secure, end user experience possible. To support that commitment, the OneDrive Desktop application (sync client) will look to phase out support for Mac OS X Yosemite 10.10 and 10.11. These changes will go into effect February 1st, 2019. Note: Mac OS X Yosemite 10.10 has been out of mainline support since August 2017.
- Existing OneDrive sync client installations on unsupported operating systems will stop updating. These clients will continue to run, but functionality will no longer be tested. It is not advised to continue to run on these unsupported operating systems.
- New installations on unsupported operating systems will be blocked.
- Bugs and issues found on or specific to unsupported operating systems will no longer be investigated or fixed.
Retirement of 3DES in Office 365
Effective: February 28, 2019
Details: As previously communicated (MC124104 in October 2017, MC126199 in December 2017 and MC128929 in February 2018), we are planning to move all of our online services to Transport Layer Security (TLS) 1.2+ to provide best-in-class encryption, and to ensure our service is more secure by default. As part of this plan, we’ll be retiring 3DES beginning February 28, 2019. In order to help you prepare for this change, we will be providing reports for you to track your TLS 1.0/1.1 and 3DES usage. These reports will be available starting January 1, 2019.
As of February 28, 2019, we’ll begin retiring 3DES. As a result, connections to Microsoft using the cipher 3DES will not work.
- By going to http://securescore.microsoft.com, you can find the overview of your TLS 1.0/1.1 and 3DES usage for Exchange.
- Click on ‘Score Analyzer’ and scroll to the – Remove TLS dependencies tab.
- Here you will see a summary of your TLS 1.0/1.1 and 3DES usage.
- If you want more details on who is connecting using these weaker ciphers and protocols – click on the ‘Get Details’ button that will launch a flyout where you can click on ‘Launch now’.
- This will take you to the Secure Trust Portal (http://servicetrust.microsoft.com) where you can download your user and agent information.
Retirement of support for Third-Party Audio Conferencing Providers in Skype for Business Online
Action Required by: April 1, 2019
Details: Beginning April 1, 2019, we are retiring support of our integration of third-party audio conferencing providers (ACP) in Skype for Business Online Meetings. On April 1, 2019, the following changes will be observed:
- Participants who attempt to join any Skype for Business meeting via dial-in numbers provided by a third-party ACP service will no longer be connected to the Skype for Business meeting
- Users enabled for a third-party ACP service will no longer have their dial-in information automatically included in any new Skype for Business meeting invites
To prepare for this change, we encourage affected organizations to notify their enabled users of this planned update prior to April 1, 2019. After this date, users can continue to use Skype for Business with no interruption to their online meetings; however, organizations will need to enable their users for Audio Conferencing if they require dial-in audio conferencing with Skype for Business or Microsoft Teams.
Depending on the desired end state of the organization, there are three paths that can be followed:
- Migrate to Microsoft Audio Conferencing
- Continue to separately use a third-party audio conferencing provider
- Stop using dial-in conferencing altogether
For more information, please review the details provided at the link below in “Additional Information”.
Discontinuation of support for Session Border Controllers in Exchange Online Unified Messaging
Action Required by: April 30, 2019
Details: In July 2017, we announced that support for Session Border Controllers (SBC) that connect third party PBX systems to Exchange Online Unified Messaging (UM) would be discontinued as of July 2018. After feedback from customers and partners concerned about this change, we are announcing additional time for customers to prepare. The new date for discontinuation will be April 30, 2019. Customers with existing deployments remain fully supported until this date. However, Microsoft strongly advises all customers to begin their voicemail transition now.
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)
We’re removing Visio Web Access from SharePoint Online
Action Required by: September 29, 2019
Details: Last September, we announced that we would be removing Visio Web access from SharePoint Online. Since then we have listened to your feedback and are extending the timeline to September 2019 to allow more time for the migration of your existing Visio content to the newer platforms.
Beginning September 30, 2019, 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.
Microsoft StaffHub Retirement
Action Required by: October 1, 2019
Details: Effective October 1, 2019, Microsoft StaffHub will be retired. We’re building StaffHub capabilities, including schedule and task management, into Microsoft Teams. The Teams mobile app now includes shift management and a home screen experience. Additional capabilities for firstline workers will roll out to Teams over time. These changes are part of our continued efforts to empower every employee with Microsoft 365. With capabilities for firstline workers now in Teams, every employee in your organization will be able to use Teams to streamline their workday, collaborate with coworkers, and access information and expertise to help them do their best work.
Retirement of Skype for Business app on Windows 10 Mobile
Effective: December 2019
Details: The Windows Phone app for Skype for Business is being retired. After this change takes effect, new users will no longer be able to download the app from the Microsoft Store, and the app will no longer be supported. Although Microsoft continues to support Windows 10 Mobile, we are not focused on building new features for the system. We will continue to invest in Skype for Business mobile apps for iOS and Android and also in desktop apps for Windows and Mac.
Existing users of the Windows Phone app for Skype for Business will continue to be able to use the app. Moreover, they will continue to be able to re-download the app from the Windows Store.
Beginning in December 2019, Skype for Business on Windows 10 Mobile, will no longer be available for download.
The Skype for Business app may continue to work after this date, but this is not guaranteed. This app will no longer receive updates or support. If you need to continue using Skype for Business on Windows Phone, we recommend that you install the app before the date cited above.
