Office 365 - Disable External Incoming Email on a schedule

[RichCowell]

Hi All,

 

I need to look into options for stopping / bouncing / holding external emails from being received during the hours of 1900-0700... For all members of a certain security/distribution group...

 

Disabling those accounts completely is not ruled out as a solution, but I'd rather continue to let them access their emails and send/receive internally.

 

Does anyone know if this is possible, and if so, how?

 

I'm guessing it'd be a powershell script that could be scheduled to run disable & enable etc. but not got a clue about that!

 

Thanks,

 

Rick

Can't you do this in the Transport rules?

Yes, I'd looked at rules as I have a few set up for various things already, and they can be scheduled with a start and end date, but they'd have to be scheduled manually each day/weekend... so not really a practical solution... Unless I've missed something... I've had a good luck though...

Script the Transport rule changes with Powershell. Run the Powershell script on a schedule?

I thought that's what I may have to do... I don't know Powershell at all though - do you know where I'd find a script to do that?

Easiest thing to do is to set the transport rule up manually and use 'Enable-TransportRule' and 'Disable-TransportRule' in two separate scripts. They are basically one liners then.

Sounds perfect, thank you!
