Email: Outlook classic desktop error when setting automatic replies on shared mailboxes

Incident Report for Cardiff University

Identified

Some users may encounter an error when attempting to set an automatic reply (also sometimes called an out-of-office) for a shared mailbox using the Microsoft Outlook classic desktop app.
If affected, the error message states that the reply settings cannot be displayed because the server is currently unavailable.

This issue has been raised with Microsoft, and in the meantime those affected can use Outlook on the web instead via a browser to perform the action.
