... and once again, having to recreate the account after deleting everything in the Outlook folder (except my work OST file) this morning.
This time I took a backup of my Outlook folder, however. Check this diff out ... On the left is the newest autodiscover XML file, and on the right is the backup I made last night.
Why, with the registry key set as you described earlier, would it be screwing up the XML file?
In case it's not obvious -- the new XML file on the left contains all office365 stuff, and the one on the right is my original XML file with my smartermail server.
Right-click the above image and open in a new tab to see it full-size.
Where's it even getting this stuff on the left?
Even if I change the XML files back, it still won't go back to connecting again.
