Title: Some users may be unable to use spell checker in the new Microsoft Teams
User impact: Users may be unable to use spell check in the new Microsoft Teams.
More info: As a workaround, affected users may be able use the following steps to clear their cache:
– Close and quit the new Microsoft Teams application
– Delete the folder: %localappdata%\packages\msteams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
– Start the new Microsoft Teams application
Current status: We’ve developed a Teams-side fix for this issue that will enable spell checking by modifying the configuration changed by the code regression. We expect this fix will completely deploy by our next scheduled update. Some users may still find relief by updating Windows with KB5034123 (OS Builds 22621.3007 and 22631.3007).
Scope of impact: Some users attempting to use spell check in the new Microsoft Teams may be impacted.
Start time: Wednesday, January 10, 2024, at 6:26 PM UTC
Estimated time to resolve: We expect that the issue will be fully resolved by Wednesday, February 14, 2024.
Root cause: A recent service update to improve the right click menu for spelling errors to display suggestions that would be relevant to the current language Microsoft Teams is in includes a code regression.
