Forgot to post the endusers comments. I tried cranking up the diagnostic logging to level 5, but didn't see anything odd, I see the connection, the check of uidl's and the download of messages. > Hi Harondel- Here are further details of the problem I described to you > yesterday. > > Yesterday Outlook would "stall" at 150Kb of 155Kb (for example) and I > would not receive all of OR any of my messages.
