Trent Colson : "Our organization had been working on Microsoft Exchange Outlook environment since the very beginning. All our data has been exchanged over the server by the connected user machines. However, a technical issue with the server recently caused to put it under maintenance. A large number of employees worked even from home, and had been using offline mailbox for the same purpose. Therefore, due to this unplanned downtime they have been left affected. Most offline OST mailboxes are now in an unusable state, which has hampered a lot of work. We were wondering of a way through which independent accessibility can be availed until the server is back up and running."
