Where Microsoft Teams leaves files
| Location | What it is | After uninstalling |
|---|---|---|
| ~/Library/Containers/com.microsoft.teams2 | Cache, settings and sign-in for the current Teams | Safe |
| ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams | Data shared between Teams components | Safe |
| ~/Library/Application Support/Microsoft/Teams | Classic Teams data, if you used it | Safe |
| /Library/Application Support/Microsoft/MAU2.0 | Microsoft AutoUpdate, shared with Office | Leave alone |
In Finder choose Go › Go to Folder (Shift-Command-G) and paste a path to open it. Safe means nothing you made is inside; Check first means it may hold the only copy of something. To see how much space they use, run this read-only command in Terminal:
du -sh ~/Library/Containers/com.microsoft.teams2 ~/Library/Group\ Containers/UBF8T346G9.com.microsoft.teams ~/Library/Application\ Support/Microsoft/Teams 2>/dev/nullNew Teams and classic Teams
The current Teams for Mac uses the bundle ID com.microsoft.teams2. Classic Teams, which Microsoft has retired, used different folders under ~/Library/Application Support/Microsoft/Teams. If you upgraded, you may have both.
Don’t break Office
UBF8T346G9 is Microsoft’s developer prefix, so you’ll see several Group Containers starting with it, such as UBF8T346G9.Office and UBF8T346G9.ms. Those belong to Office apps and your Microsoft sign-in. Remove only the one ending in .com.microsoft.teams. Microsoft AutoUpdate also updates Office, so keep it unless Teams was your only Microsoft app.
Keeping Teams but it’s misbehaving?
Quit Teams and clear its cache instead. More about com.microsoft.teams2

Frequently asked questions
Does dragging Microsoft Teams to the Trash uninstall it completely?
No. It removes the app, but Microsoft Teams leaves 4 kinds of files behind in your Library and elsewhere: cache, settings and sign-in for the current teams; data shared between teams components; classic teams data, if you used it. The steps above remove them.
What is Microsoft Teams’s bundle ID on Mac?
com.microsoft.teams2. Most of its leftover files and folders are named after it, which is how you (and TidyMac) can tell they belong to Microsoft Teams.
Can I reinstall Microsoft Teams later?
Yes. Download it again from Microsoft. Anything stored in your account online comes back when you sign in; local-only data you removed does not.
