I am using Office 2013 tied to an Exchange 2013 email account. Recently I noticed that emails were being deleted from my inbox. I noticed that the email was on my phone but as soon as I opened Outlook, it deleted the message (which of course removed it from the phone).
It doesn't delete all emails - just some of them - and it only seems to impact the inbox as near as I can tell. In fact, I tested two emails with the exact same content changing only the subject line. One email was automatically deleted (and was found in the recoverable items) and the other wasn't impacted at all. Here's what I've looked at so far:
- Doesn't seem to be a view setting - the email can be recovered from the deleted items so the email is actually getting deleted.
- Checked "manage rules & alerts" and there are no rules that delete emails - plus the example email that we have doesn't meet the criteria of the rules anyway
- Checked the Exchange server - there are no rules configured on the server that delete emails
- If the sender (any sender - not just the original person who sent the message) changes the subject line, the email will remain in the inbox. If they send it with this subject line, it will get deleted
- Recovered one of the emails and checked the "ignore" button - the ignore button was not pressed which leads me to believe the conversation is not being ignored
- Started outlook with Outlook.exe /CleanConvOnGoingActions just to make sure - no change in the behavior (emails still get deleted)
- Checked junk mail settings - nothing is configured to permanently delete an email.
- Deleted the profile from the computer and recreated it - no change in behavior
I'm out of ideas on what to check. Please help if you can shed some light on a new direction to take this investigation
