Hi Paul,

The first thing I would look into is the line PopCmdResp: -ERR Message corrupted

It may be that there is a corrupted email message within that mailbox that it is struggling to process.

Another thing to look at are App passwords.  it might be that 2 factor authentication has been enabled in Office 365, and an app password needs to be created in Office 365 for Hornbill.
