There are two ways that permissions can be given to a service account for GAL or Public Folder sync to user mailboxes:

  • The IT Admin can delegate user permissions to their service accounts.
  • The IT Admin can also set impersonation mode on their service account.

This guide shows how to set up impersonation mode on a service account.
