Microsoft Reducing Recovery Time for ex-Inactive Mailboxes to 30 Days

Microsoft plans to reduce the recovery period for inactive mailboxes newly released from retention holds and policies from 183 to 30 days. The change will be implemented worldwide by the end of September. The reduction in recovery time sounds seriously but it's really not. If you haven't figured out that you need to recover some data from an old inactive mailbox within 30 days, the data probably isn't needed. And anyway, if you really want to, you can keep inactive mailboxes forever.
