User Impact: Users would have seen a frozen white screen when attempting to sign into the OneDrive for Business sync app.
More info: This issue might have affected users who have the Microsoft Exploit Protection EAF (Export Address Filtering) feature enabled and have installed the September security updates.
We've confirmed that users with Mobile Device Management (MDM) enabled devices could have added the following reg key as a workaround:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 2767781516 /t REG_DWORD /d 0 /f
We've also confirmed with affected users that disabling Export Address Filtering (EAF) was a potential workaround to alleviate the impact. Admins who wished to do so could have navigated to Windows Security > App & Browser Control > Exploit Protection Settings > Program Settings > OneDrive.exe > Turn off Export Address Filtering (EAF) and mitigated the impact.
Alternatively, this issue could have been mitigated using Known Issue Rollback (KIR):
https://techcommunity.microsoft.com/t5/windows-it-pro-blog/known-issue-rollback-helping-you-keep-windows-devices-protected/ba-p/2176831.
For enterprise-managed devices that have installed an affected update and encountered this issue, it could have been mitigated by installing and configuring a special Group Policy installed via an MSI file available for:
- Windows 10, version 1809 and Windows Server 2019: https://download.microsoft.com/download/7/f/1/7f194890-eea9-4cad-b19f-25ab67e41bbe/Windows%2010%20(1903%20&%201909)%20Known%20Issue%20Rollback%20091721%2001.msi

Note: Devices needed to be restarted after configuring the special Group Policy. For help, users could have reviewed the following:
https://docs.microsoft.com/en-us/troubleshoot/windows-client/group-policy/use-group-policy-to-deploy-known-issue-rollback
For general information on using Group Policies, see:
https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-r2-and-2012/hh831791(v=ws.11)
Please note that many Mobile Device Management (MDM) customers couldn't deploy group policies. Customers that were unable to deploy group policy settings for the KIR may have opened support cases for further assistance.
Final status: After an extended period of monitoring, we have confirmed that the fix within the October Windows update successfully resolves the issue and affected users have reported relief. Any user still experiencing impact will need to initiate the update on their device to remediate the issue.
Scope of impact: Any user may have been prevented from signing into the OneDrive for Business sync app.
Start time: Monday, September 13, 2021, at 8:26 PM UTC
End time: Tuesday, October 12, 2021, at 5:00 PM UTC
Preliminary root cause: A recent Windows patch deployment inadvertently introduced an Export Address Filtering (EAF) issue that's contributed to the impact.

User Impact: Users can't see some chat messages in the Microsoft Teams desktop app.
More info: In addition, some users may see an Oops page when signing in, can't receive messages when switching between tenants, or can't see channels and chats on the sidebar.
Users who have access to the Microsoft Teams web app may be able to use that connection method as an alternative to avoid this issue whilst we develop a fix.
Current status: We've received reports that various users are unable to see or receive some chat messages, may see an Oops page when signing in, or can't see the channels and chat in the sidebar when using the desktop client. We've determined that an ongoing service update intended to improve the desktop client performance is encountering various transient issues during the implementation process for a limited number of users. We expect that the vast majority of users can resolve this issue by either fully closing the desktop client (Right-click on Microsoft Teams on the taskbar and select 'Quit') and starting Microsoft Teams again, or signing out and signing in again. If users are still affected after performing the previous steps, we suggest leveraging the web app, if possible, and reaching out to support for additional follow up. In parallel, we're working on developing a fix to remediate impact for continuously impacted users and expect to have an update by Tuesday, September 21, 2021 on its progress.
Scope of impact: A limited number of users leveraging the Microsoft Teams desktop app may experience impact outlined in the User impact and More info sections.
