I have Microsoft Basic account and use onenote a lot (web app) but it's problematic when internet is patchy. I tried to use the desktop version but when I try to login I get the message:
Another account from the same organisation is already signed in. To switch accounts, please to to Applications/Utilities/Keychain access, clear all entries including the 'office' keyword, and then restart the app.
I did this, deleting office related cache, restarted and got the same error message. I thought it must be because I was on basic package which doesn't include all desktop apps so I upgraded to standard MS package. Same problem. I tried logging out of all MS products and trying to launch desktop onenote but same error message again.
I deleted onenote app and reinstalled latest version today. Same error.
There are only 4 of us in the organisation and no one else has logged in as me.
I am using mac os catalina: version 10.15.7
Google chrome Version 100.0.4896.75
OneNote version 16.59
Any ideas for how I can login to the desktop version of onenote?
Thanks!
