Then the function to edebug is `gnus-get-unread-articles'. That's going
to be a long boring slog (if you have many other servers, maybe close
them first), but it ought to show you what's going on.

I'd recommend starting the edebug, then jumping to line 1701 (in Emacs
master), and checking out the value of the "type-cache" variable (got to
love Gnus' impenetrably-named variables). That should hold a list of all
the servers that Gnus is going to check groups for. Either the Exchange
server won't be in there (in which case start over and follow from the
top), or it will be (in which case follow on from there, and see what
happens).

Wish I had a better solution!
