Servicecamp will not pickup emails from inbox.

Hi there,

We keep getting this issue where everything is working fine for months, then we notice that service camp is no longer receiving new tickets/Emails from the inbox.

It is just a standard Office 365 account. Servicecamp doesn't suggest that there is an error. I have added the account again as IMAP, and still not pulling in the 5 emails in that inbox.

Can anyone suggest anything? Kind regards
