Users cannot access "Out Of Office" settings through "Outlook." The following error occurs when attempting view the settings from Outlook - "Your automatic reply settings cannot be displayed because the server is currently unavailable."
For example, user accounts are migrated to the target with QMMAD. The users logon to their workstation with target account credentials. User then launches Outlook with source credentials and attempts to view their settings. While Outlook can access mail they cannot see their Out of Office settings.
See the following Microsoft link for a potential Registry hack to resolve the issue on workstations.
