Exchange 2013 mailbox issue
I would like to ask someone with Exchange expertise for advice
Last time my Veritas backup exec screwed my Exchange server. In process of backup for over 2 weeks start created new maiilbox snapshot so after 2 weeks I've got 10 VM snapshots.
This caused my incremental backup to take 19 hours to complete.
I've decide to delete snapshot from VM console but somethings went wrong and after restart one of my databases reported error.
I've restored database from backup so all works good now. Never mind, but I've notices strange situation on one of my mailbox.
I have user with unlimited quota and Exchange is showing his mailbox size over 31 GB, but when I've checked his Outlook 2016 folder, the size of OST file is only 4GB and settings for his outlook is to use cache mode so I don;t understand why information store is showing 7x more taken space.
