Switching Tenants/Profiles in Office for the Mac

hi Ascendant​  I’ve run into the same challenge on macOS. Unlike on Windows, Office for Mac doesn’t yet let you stay signed in to multiple tenants and easily switch between them inside Word/Excel/PowerPoint.

A few workarounds that help:

1.Sign out / sign in within the Office apps – In Word (or Excel/PowerPoint), go to the top menu → Word > Sign Out. Then restart and sign in with the other tenant account. This changes your active session, but it signs you out of all accounts until you switch back.

2.Browser profiles – Using Edge or Chrome profiles per tenant works well. Open docs from the right tenant in Office on the web, then choose Open in Desktop App. This keeps tenant sessions separate.

3.OneDrive / Teams launch – Opening files directly from the OneDrive client or Teams app signed into the right tenant will often ensure the desktop Office apps use that identity.

4.Separate Mac profiles – For strict separation, you can create a second macOS user account and keep Office signed into a different tenant there.

At the moment, Mac users don’t have the same “quick switch” experience available on Windows, so the best workaround is browser profiles + Open in App if you need to work with multiple tenants in parallel.
