Shared Mailbox cache behavior in Outlook
Large OSTs or excessive number of folders are no-go, best use OWA in such cases. Or create a separate Outlook profile with just the shared mailbox.
We use the policy of turning off the Download Shared Folders check box. This forces the users to access any mailbox besides their own directly from the server copy. It causes a slight delay opening, but we no longer receive the constant help desk calls about mailboxes not showing all messages. It also helped with all the replication issues for admin/manager calendar updates.
If you add a new account for the shared mailbox within the user's existing Outlook profile, it will create a separate (or multiple if using the slider) OST file that is a lot easier to manage.
Also allows you to manage delegation, OOF, rules etc without needing to exit Outlook and use a separate profile.
