Since my upgrade from 13 to 16, Outlook has been temporarily losing IMAP folders. I have rules set up to redirect email into various IMAP folders. However, every day (pretty much) these IMAP folders disappear temporarily and then reappear. (This is not happening to all the IMAP folders, just a few, may those with rules attached?) The net result is that all my rules have errors and need manually correcting (the "specified" folder is always missing) and I have to set my my favourites again because they are no longer showing.
I am having to go through this process almost every day, wasting cumulative hours. This is a big step backwards for me.
Any suggestions?
