Guys,
Is there a way to do this ?
I have a scenario where we are migrating users to Office365. The migration process involved exporting the user's vault back to the original mailbox to be migrated to the O365 archive. The mailbox needs to be emptied first to eliminate duplicates.
I originally thought of using exmerge to empty the mailbox before rehydration, but exmerge will only do 2Gb. I then thought of removing the exchange attribs for the user and recreating the mailbox. This works splendidly for having an empty mailbox but then presents the issue of having to re-associate the existing archive.
So I am looking for suggestions on the best way to achieve emptying or deleting/recreating the mailbox to ensure it is ready for vault rehydration.
Thanks in advance
