Email sent to and Exchange online resource is being auto-deleted.
First, we're in a hybrid environment and have been that way for a few years. Everything has worked great, until about a month ago. At that time, email sent to resources started being auto-deleted. ...
It's an option of the resource mailbox:
Set-CalendarProcessing roommailbox -DeleteNonCalendarItems $false
For more info refer to the cmdlet help: https://technet.microsoft.com/en-us/library/dd335046(v=exchg.160).aspx
In addition, you might want to check for rules, both Inbox and Transport ones.
