How to archive Exchange mailbox?
Posted on 2016-10-19
There is a MS Exchange organization, with 5 Exch 2010 servers holding different roles. 3 of them on hub transport and mailbox, and 2 of them are CAS. There are 2 mailbox databases, both on DAG. The problem is, we found that few of the mailboxes (altogether 250+) are exceed 20 GB. These mailboxes are still active, although the mailbox owner already left the company. However, other users still have to access, especially to grab and share those latest incoming mails, we have to leave them live.
Now, both exch mailbox databases are in 500+ GB, we are thinking of doing some kinds of house keeping, at least to avoid/slow down the growth of the mb DB. We are thinking for those exceed 20 GB, we just want to keep those mails that dated this year, and take away mails that were last year of before. Are we suppose have to archive them? But, can I only archive those mails that based on date? or export them to PST?
Another condition is, suppose only this year's mails are kept on the mailbox, others are archived or kept some where away from server. But, if users want to see mails that are belong to last year one day, what am I suppose to do to fulfill their need?
