Please excuse my ignorance as I have inherited an Hosted Exchange 365 environment that I am not accustomed to nor have much knowledge.
We need to make sure we have the following guidelines met and I am not sure where to look/how to set this up. I am looking for some advice/direction.
1) We need to keep all email for 5 years - no deletion at all from the mailbox
2) We need to do archiving to keep things clean in the mailboxes
Those are the basic requiements and we are on Microsoft Exchange 365
Thanks for any help!
