Template:Archiving Exchange Shared Mailbox
Shared mailboxes grant multiple users shared access to a mailbox, somewhat comparable to public folders.
A shared mailbox is a special kind of mailbox that, unlike a normal mailbox, is associated with a disabled Active Directory account. Like for normal mailboxes, MailStore is able to create user entries for shared mailboxes via Active Directory Synchronization. For this, you have to deactivate the option Synchronize enabled users only in the section User Database Synchronization.
After synchronization you can grant MailStore users access to the archive of the shared mailbox by assigning privileges.
Step 2: Setting up the Archiving Process
In order to archive emails from a shared mailbox you must grant a user account full access to that mailbox (either by delegated access or impersonation) because the Active Directory user account associated with that mailbox is disabled. You can use the service account you created to archive multiple mailboxes for this purpose.
Once you have created the service account, setup a new Single Mailbox archiving profile. Enter the credentials of the service account and fill the optional Mailbox field with the primary e-mail address of your shared mailbox.
Further steps are analog to the archiving of individual Exchange mailboxes.
