O365 - Tennant wide power flow (Automatic Replies)

[TheRobins]

Wonder if anyone has any clever ideas for this one. I am looking at setting up automatic replies for all users and shared mailboxes that cuts in outside of office hours and weekends, so people are aware staff will not be replying to their emails at 11.30 in the evening. I have set it up for a single user as a powerflow, just wondering if there is any clever way to apply it to a large group of users?

 

Any ideas greatfully welcomed.

I think this is possibly the wrong tool for the job if you are looking to take a flow that configures a personal mailbox against the entire estate

 

You can get and set replies like this via graph api which you can call via flow, but you're gonna have to worry about rate limiting and the performance isn't stellar so if you're talking thousands might take a while

 

I would be tempted to have a transport rule in exchange, triggered by group membership and then turned on-and-off by some kind of automation ( simple powershell job on a server or azure runboook)
