We use a third party for our O365 email archive. We have run into a situation where we have a legal settlement that directs us to delete a date range of emails totaling over 100k emails. Currently the Barracuda archiver only allows single message deletion. I'm looking for help on this. I would appreciate any suggestions on what can be done or who to contact to expedite this process. I have to sit on a shared remote session with legal and have them watch me delete each and every email. I envision a long, slow and clanky web interface experience.
Any one from Barracuda...do you have a tool for this?
