So, my org recently migrated from OMEv1 to OMEv2. Most recipients are able to open the messages inline inside of OWA, and Outlook desktop just fine. But some are able to only view them in OWA.
Here is an example from one of our partners:
- On desktops running windows 7 and 10 using Office/Outlook 64 bit version it would not open the secured email. Both the operating systems and Office/Outlook were up to date. A fresh windows image and a new install of Office were used and they also would not open the secured email. A new Outlook profile would not open the secured email. The recipient is running Office version 1909 Click-to-Run.
- On mobile devices running Outlook on iOS, the message opens inline without any issue.
- Logging into OWA for Office 365 (test on both chrome and firefox) allows the secure email to be opened.
It appears that only the outlook client is having an issue.Is there anything else that I can look into on the Outlook client side? I've tried clearing credential manager for anything pertaining to Office, signing out of and back into Office, with no luck. I'm stumped...
