Office 365 - Outlook getting "Could not connect to public folder server" error

I have a client who is using Office 365. Two of the users have access to a shared mailbox. They do not use public folders and none are set up.

One of the users has a "sync issues" sub-folder under the shared mailbox. It is full of messages saying that it could not sync to the public folder server.

What might be causing this error.

Hi Roy,

Is the user on a domain? Can you check if the user's domain and/or Office 365 passwords are close to expiring?

If you are not seeing any actual issues, you can pretty much ignore every message under the "Sync issues" folder. And have them switch to the Mail view (CTRL+1), so they don't bug you with future complaints about the folder :)
