ON my MAC desktop - the authentication period has expired - please sign in again

Hi Kevin,

Sorry for the inconvenience. To investigate the issue, I'd like to first confirm the following things:

1. Where are your notebooks stored, in consumer OneDrive (https://onedirve.live.com) or OneDrive for Business (https://domain-my.sharepoint.com/personal/xxx)?

2. By "creating new account", do you mean create a new Microsoft account and then sign into the OneNote app? If yes, I suggest you create a new Mac account, log into Mac with this account, open OneNote to test with your problematic account.

3. Click OneNote on the top bar>About OneNote>let us know the version of it.

3. version of one note is V16.16

Hi Kevin,

You may create a new Mac account as mentioned in my last post. Let's check if the issue is related to a corrupted Mac user profile.

Regards,

Tim

I have created a new MAC account and now one note is working properly. 

Now how do I fix my main account so `i can use one note on it?

Hi Kevin,

If OneNote works properly with the new Mac account, it means the former Mac account profile is corrupted. We would suggest you use the new Mac account in your daily work. If you choose to investigate with the corrupted account, as it's more related to Mac OS, you may need to contact Apple support for further investigation with that account.

Thanks for your understanding.

Tim
