Can't sign in to an Microsoft 365 app on Mac

Liu, Jun 0 Reputation points

I'm using macOS Monterey 12.3 M1 chip. I downloaded Microsoft 365 from the App Store and used my university account to sign in. Last week I found my app was logged out, and it showed "Sorry, another account from your organization is already signed in on this computer." when I tried to sign in.

I tried the solution at, but it didn't work.

    I fixed it by deleting not only "Office" but also "Microsoft" entries in the Keychain Access app.
