My nightmare began late last week when I was tasked with updating our Exchange 2010 server so that a few of my users could use the new IOS Outlook apps to connect. At that point the SBS 2011 server only had SP1 installed. I had only recently taken over duties for this server. My thought was.. well I'll just install SP2 or SP3 and everything will be happy... yeah.. not so much.
Long and short of it, the updates continually failed while installing the hub transport role and the result was a partially installed service pack and a broken Exchange Server. We can no longer open the EMC due to a Kerberos error and users cannot access OWA as they once could. Local Outlook clients also cannot connect.
After hours of banging my head against the wall trying to recover the install of Exchange, we've bailed. There was always a desire to move to Office 365 so now became the natural choice of time to do it. Office 365 is up and new mail is flowing properly.
My issue now is recovering historical email data and migrating into the new 365 environment. Users who used Outlook with cached mode are easy enough. My issue lies with a couple of users that only ever used OWA to access their mail.
Is there a way to recover that user's mailbox directly from the Exchange data base WITHOUT being able to access PowerShell or EMC?
Any help is much appreciated.
