we have a forest with two trees that hold one domain each. There is a default tree-root trust (transitive, two-way) between the top domains. Since both trees are in the same forest they share the same global catalog and schema.
We configured a button in Adaxes (Version 2017.2) to manage the "Send on behalf of" and "Full Access" properties of our shared mailboxes in Exchange. We used the built-in functionality from Adaxes. The shared mailboxes are all held in one OU of our forest root domain. We use an OU-filter to list all operation targets.
As long as the shared mailboxes are of the type "Regular" everything works fine. If we change the type of a shared mailbox user to "Shared" the "Full Access" property cannot be managed with Adaxes anymore. Adaxes shows the error message "Multiple objects with Sid S-1-5-10 were found".
Any help would be appreciated, thank you!
