May Tuesday patch causes Teams and Outlook login failures and Microsoft already knows

It’s been days since Microsoft released the May patch on Tuesday, and after that we saw the Windows 10 May 2021 update arrive. A fix we saw later was causing performance issues in the Windows 10 May 2021 update. Teams among other failures, to which we are now adding failures related to Teams and Outlook.

Another update from Microsoft that causes crashes on computers that have been updated and whose owners complain that after updating they are having issues trying to sign in and sign in to Teams, Outlook and OneDrive for Business.

Problems with Teams and Outlook

Some users are expressing their dissatisfaction with the latest update preventing them from signing in to services like Teams, Outlook, and OneDrive for Business. Failures and issues that Microsoft is already aware of that may cause the “80080300” error to appear when trying to log in or sign in.

“After you install this update and restart your device, you may not be able to sign in to some Microsoft 365 desktop client apps, such as Microsoft Teams, OneDrive for Business, and Microsoft Outlook. You may also receive an error 80080300 or “We found a problem. Reconnect … “when trying to authenticate or connect to Teams”.

Microsoft claims that this issue exclusively affects computers that have Windows 10 security update KB5003169 (version 1909) installed and that the bug appears to be related to code included in the latest Windows 10 update bundle.

For those who encounter the error, Microsoft recommends restarting the computer manually, as this seems to resolve the issue in some cases. Another option is to restart the applications.

To alleviate this problem on most devices, you can restart your device a second time. Most devices will connect to affected apps as expected for all subsequent reboots after the first reboot that completes the update installation. If restarting does not alleviate the problem on your device, you can use the web versions of the apps.

Solutions to correct the problem but in both cases these are interim solutions as long as a definitive solution arrives in the form of a patch in which they claim to already work.
