Exchange Hybrid - Quick Question on Transport Rules

[CyBeRkId2002]

Hi all,

 

We are in the process of migrating our mail from on-prem to cloud. I am guessing if there is no reason for an email to pass-through our On-Prem system (Exchange Online to Exchange Online, or Exchange Online to External for example) then out local transport rules would not apply.

 

We have around 30 of these for various different reasons, do I just have to recreate them on exchange online?

 

Cheers.

All depends on how you are migrating. Are you having your emails hit Office 365 first or your on-prem first?

 

If your emails are going through your onprem first and then to office 365 then the current transport rules you have setup will continue to run. However if emails hit office 365 first and then on-prem they will not run.

 

If you wish to keep all your transport rules then you will need to recreate them in Exchange online as the hybrid migration will not migrate these over.
