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

This is the genius. This worked like a champ!!!!

create an on Microsoft email alias and make that your primary email and then try again removing the licence and reset office tools using this login

Actually you are incorrect. I finally got a competent microdots agent to sort it out. Very much on Microsoft's side..

Hi I think you have completely ruled out installation and client-side issues. This is on your system admins.

Obviously I did that first off. I can't even log in with a different account as the error remains the same.
