IMAP and POP verbose logging
AFAIK no.
There are 3 things I would consider:
1. Determining how users are accessing their mailboxes in Office 365: https://www.cogmotive.com/blog/office-365-tips/determining-how-users-are-accessing-their-mailboxes-in-office-365
2. You could enable Outlook logging and collect the log files i.e. on a file share.
3. Enable mailbox audit logging for those mailboxes and check if the log contains some information about IMAP and POP access and maybe activities.
Thanks for outlining the options, Dominik Hoefling! Other than enabling verbose logging in Outlook (which slows Outlook), I have done the other 2, but have not gotten the information on IMAP detailed events logging. I saw that the account connected via IMAP, but I did not see if the Inbox folder was downloaded, or emails were synced.
Thanks again!
