Regaining Access to an Encrypted PST
Posted on 2012-08-26
Several workstations used to login to a domain, even though the domain controller had previously bit the dust many years ago. In the interim, they used a NAS that didn't require domain login, but accepted the access from those on and off the domain platform.
Recently, they installed a new server, which became the new Domain Controller, and used the same name used in the previous domain (company.local.) One by one, the workstations rejected the new DC and login to local accounts became impossible.
Through some efforts, the workstations were joined to the new DC and the old profiles were migrated to new ones- with one exception. The Outlook PST files were previously encrypted and migrating the file still will not grant access to import the data.
One workstation taken offsite managed to login to the old domain one last time and I was able to successfully export the PST without encryption, so I know it can be done. But once the workstatoins are joined to the NEW domain, is there any way to get access again?
I need to either: 1- Decrypt the data so that the PST files are accessible, or 2- Regain access to the profile so I can export the file safely.
Does anyone have any ideas?
