I have a user whose primary Exchange Online mailbox had hit the 50GB limit, so In-Place Archiving needed to be turned on in order to make room in live mailbox.

However, the user wants to be able to have ALL the Calendar items accessible in the live mailbox.  They are fine with the Archived email items remaining in the In-Place Archive.   So the questions I have are:

If I set the user’s MRM policy on the Archive Mailbox to ‘No Policy’ but leave In-Place Archving active, would I be able to export the Calendar items from the In-Place Archive to a PST (via Outlook) and then re-import them into the live mailbox?    If the above were possible would all the Calendar items import back into the live mailbox’s calendar in the same state they were in, in the In-Place Archive (i.e accepted, etc.)If the items reimport, will Outlook Reminders get triggered for all the re-imported items, in that the user would get a whole list of Calendar items showing up as Overdue?
