I have a VSTO addin for Outlook 2013. The odd thing is sometimes when I do something seemingly unconnected. My button group disappears from the place it was in. Was there working perfectly for a long time. I added a ribbon group launcher, and it vanished. I then rolled back the pending changes and it still isn't there.
First, why does my ribbon group always disappear, it is set to Position: AfterOfficeId GroupMailDelete and the tab is set to TabReadMessage. This has always worked for me up until just now. I looked up the Office Id's for elements in office 2013 in the docs and they are correct (and as I said it's been fine for months).
Second, why does it not reappear when I rollback changes? I only changed that file and when I rolled back it looked like it did before I touched it.
Also it was working right until I made the change. Tested before, worked, tested again my ribbon group is gone.
I really can't stand this problem as it messes up my entire addin. Someone please offer assistance as none of the other SO answers or anything else I've found have helped.
Thanks a ton
EDIT:
Rewrote the program copying over the logic and redoing the ribbon and forms in designer. Register the event handlers was a pain as was constructing the two forms, one from EF and one using raw sql. But aside from that it works now. Why would it work when I rewrite it, but still not work when I rollback the breaking change? Not to mention that same change didn't break the copy I rewrote.
