After moving or creating a linked mailbox in a new domain with Exchange 2010, mailbox permissions are not synced correctly with the archive. The archive does not include account permissions for the user's new domain, and therefore the user will not have permissions to his archive.
This issue is addressed in the following release:
Enterprise Vault 10.0.2 cumulative Hotfix 2 Release
- Stop all Enterprise Vault services.
- From the Enterprise Vault installation folder (default is "C:\Program Files (x86)\Enterprise Vault"), take a backup copy of each file listed in the "Files updated" section above.
- Copy the updated files from the hotfix package into the Enterprise Vault installation folder, replacing the originals.
- Start all Enterprise Vault services.
