Global Auto Responder

[Ben O'Neill]

We recently had an issue where our network went down for a day or two. As the admin, I had to log into the portal and, subsequently, all the user accounts to set up auto responders for all users to let any senders know that we were down.

This was ok because we only have 10 users, but what if we'd had 100? Or 1,000?

Surely there's a rule that could get this done quickly and easily? I did look/try but couldn't find anything helpful.
...is there?

That's a mailbox level setting, so indeed you need to enable it on a per-user basis. You can however automate it via PowerShell. Or in general, redirect messages/create a "catch all" mailbox so that you only need to set up one reply. Would not recommend going the second route though :)

You can use a third party service for that. All you need is creating a transport rule in Office 365.
