So the issue Greg described just happened again that an empty
folder/topic "Trash" from one of my outlook accounts just shown 38
unread messages and selecting it fails with "Can't select group", while
other clients like Thunderbird shows 0 in it.  I have tried "M-g" and it
doesn't help unfortunately :(

Any more ideas for debugging?
