The Exchange server in question is a 2003 server, I tested with Firefox.
I activated debug logging in backends.local.php. I clicked in IMP  
"Folder options" > "Show all folders" and this results in debug file  
in a complete list of folders sent by Exchange server which I could  
not reproduce here completely:

Apparently the Exchange server gives the whole list of folders to IMP  
but it then fails to display. There stays a "Loading..." statement  
forever and a httpd process freaks out on server.
