My client is using office365 and I have setup journaling for some of their mailboxes. But as it seems some of the emails they have received, have not been sent to the journal mailbox.
I checked on transaction rules, but those were fine.
What other reasons can course this kind of an error?
Is there a log file which I can check to find Journaling errors?
This doesn't happen for all the emails, only for some of the emails, so there should not be any issue with journal configuration, right?
I only have access to PowerShell, can't log in to their real accounts or admin portals.
