MicrosoftReally hoping to hear more soon about what is being done to bring true parity with COM add-ins to modern add-ins. I've only seen mention of this, nothing concrete. In comparison to COM add-ins today, modern add-ins are:
On the plus side, greater stability and servicing simplicity are absolutely big wins... but nowhere near big enough wins to offset the issues above. I fear that, in the push to retire classic Outlook for Desktop, "parity" (and thus retirement) will be declared long before anything near parity (if ever achieved), as happened with Teams vs. Skype for Business and many other examples. My experience even on the paid consumer (Outlook.com) side has been dismal thus far, with only one of multiple accounts migrated from the Mail client. I submitted multiple support requests through the app, but there was a lack of awareness on the Support side that advising to uninstall and reinstall the app causes the loss of data in terms of the in-app support request itself (which showed no ticket or reference number to try to continue troubleshooting rather than starting over). After uninstalling the Outlook app, the Mail app no longer worked (splash screen for a split second, then the process disappears). None of the troubleshooting actions resolved the issue, and now, the in-app troubleshooting support is simply gone. To me, that is not a good sign, but for personal use, I give up--I just don't have that kind of time.
Until there is clarity on the modern add-ins issues and many others, I watch the march of new Outlook with a sense of foreboding, not anticipation.
