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

    This is what worked for me as well - logged in user showed immediately after deleting keychain microsoft/office keys then opening word and could then see the user that was incorrectly logged in.

    What has worked recently is the terminal command provided by Microsoft. https://learn.microsoft.com/en-us/office/troubleshoot/activation/another-account-already-signed-in

    Open Terminal and paste the following command:

    defaults write com.microsoft.Word ResetOneAuthCreds -bool YES

    It does work and has resolved similar issues on 3 different instances.
