Hi Guys,
My company is moving away from Notes to Office 365/Hybrid. The time has come to implement the On-Prem portion of the solution and we have run into a couple of issues setting up message classification/OME.
We have successfully implemented OME using message classification and transport rules for our Exchange Online users (20,000 E3 and counting). This configuration is working well.
I've copied the Exchange Online message classification details and associated IDs. Applying basic On-Prem transport rules work perfectly however I can't seem to get the following working:
1. External mail which routes via Exchange Online isn't being encrypted using existing transport rules (this works perfectly for O365 users)
2. Above applies for On-Prem users mailing 365 users (mail with message classification applied)
2. What is the best way to apply OME for mail that doesn't leave the On-Prem solution?? (On-Prem to On-Prem)
- All users will have an E3 license
- Exchange 2013 CU8
Many thanks,
Matt
