I'm running into an issue with desktop Outlook where the approval email doesn't display the actionable message functionality. I've started in safe mode and it still didn't work. I uninstalled and then installed Office and that did nothing. It doens't seem to be working for other users either when they use my demo approval flow. The functionality does work correctly if I use Outlook on the web, but just not in the desktop version of Outlook.
Oddly, I had a service account provisioned recently and the functionality works just fine for that account in the desktop version. I'm wondering if there is some setting that is different for the newly provisioned account versus accounts that have been active for some time. Any assistance would be greatly appreciated!
