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 : Delete all Keychain entries relating to Office Uninstall Office and reinstall it via portal.office.com Install removal license tool Remove all Outlook accounts and add them (as suggested here https://answers.microsoft.com/en-us/msoffice/forum/all/word-and-excel-keep-prompting-for-activation-every/a055b722-574f-4dbc-974d-a8a336a119e7?messageId=c0435c83-9040-4180-8a22-d8f5850509c1 ) 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

Thank you! Love this tool! Worked for me to clear out the old sign in from Excel.

After I combined this with office-reset tool its worked.

Thank you for providing this valuable tool!!!! I spent 3 days + working with MS Engineering support and they know sh&^%!!! This tool saved my life! Thanks again!!

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.
