I have an Office 365 subscription through my work, after recently updating Office, every time I now open Word, Excel or PowerPoint, I am prompted to sign in and activate the product. When I try to, I get this error “Another account from your organisation is already signed in on this device".

I have tried multiple suggestions as follow :

My Office apps are all up to date and I am running macOS Monterey Version 12.6.

Excel for Mac version is 16.68.

Thank you for your support.

[Moved from Subscription, account, billing/For Business/Accounts, groups management, and sign in]

EDIT : upgrading to macOS Ventura (13.0.1) didn't solve the issue

    Not sure if this has been listed here yet: https://learn.microsoft.com/en-us/office/troubleshoot/activation/another-account-already-signed-in

    I had tried the Keychain steps as well as using office-reset tool. Completely uninstalling and restarting the machine etc. None of that worked.

    Finally found the above on Microsofts website - the terminal command worked without issues:

    Open Terminal and paste the following command:

    defaults write com.microsoft.Word ResetOneAuthCreds -bool YES

    My Mac is quite new and nobody uses it except me....

    We checked our Office 365 configuration, and everything seems fine.
