QMM Project Manager right pane shows mailboxes from the wrong server (wrong domain) when expanding the Source Exchange 200x Organizations node down to Mailbox Store (mailbox_strore_name) node.
Incorrect domain controller from another domain was specified when adding the source Exchange organization to QMM for Exchange SQL database.
To resolve the issue:
1) Right-click the server node in QMM Management Tree and select Properties from the shortcut menu.
2) Click on the Associated Domain Controller page.
3) Specify the domain controller from the domain where Exchange server is located.
4) Refresh the server data, if required, by right-clicking the server again and selecting Refresh command from the shortcut menu.
Alternative solution would be to re-add the source Exchange organization to QMM SQL database, as follows:
1) Right-click the Source Exchange 200x Organizations node in the QMM Management Tree and select Add Source Organization command from the shortcut menu.
2) Make sure the correct domain (domain controller is specified as an Active Directory Domain.
3) Follow the wizard steps to re-add the source organization.
