Please make OMEv2 a proper superset of the "old" OME including server-side decryption rule
Please make sure that all the current capabilities of the "old" OME are present also in OMEv2 before decomissioning the old version.
We have a case where a third-party application sends and receives mail that may contain sensitive customer data.
We can enforce TLS between the application and Office 365, but not between Office 365 and recipient. The application needs to be able to process replies, thus they need to be in the clear when arriving at the application input.
This is possible in the old OME but not OMEv2. Thus, we cannot move to OMEv2.
