We’re experiencing a strange outlook search issue while migrating users between forests.

Here a little background.

– Forest A is the actual production one with exchange 2016 servers and users are working fine, outlook searches are working fine for all users.

– Forest B is the new forest which we are migrating users, and lately their mailboxes.

At the moment we are migrating, with ADMT, users and their PC from forest A to forest B with no issues regarding their mailboxes.
 Outlook profile is migrated correctly during the Users/PC migration and all is working fine except for the “search” in outlook client which fails.

We found, however, that if the search scope is changed from “current folder” or “current mailbox” to “All outlook items” the search works.

We cannot find what is causing the search in current folder, or current mailbox, to fail but succeding when All Outlook items is selected.
