A few very significant questions:
1] are you hosted on Exchange 2003 or 2007? 2] are you using Outlook 2003 or Outlook 2007? 3] how many items are in the key folders? (Inbox, Sent Items, Calendar, Tasks, Contacts, Notes) 4] Cached mode or online mode? 5] Can you reproduce the "white screen"? If so, when does it happen? (That is, precisely what do you do to cause it.) I've built three ASPs running hosted Exchange since 1999. I've dealt with this problem dozens of times. YOU are at a disadvantage, because you can't look at their Exmon statistics or Perfmon values. I can tell you how to help on the client side, but start off answering the questions above.

I won't mention any names. About a year and a half ago we outsourced our existing exchange server. Performance with our ASP has gone downhill steadily ever since. We are a consulting company, without any central location but an admin office with 10 people in it. Email is our lifeline to other 200 people in the company. Most of our clients don't support outgoing VPN's so we tend to use email attachments a lot. (WebDAV helps out some for intranet work, but we still do most work on email). So our mailboxes are big. The owners is about 5 Gig, mine is about 3Gig and I've cut back the NT mailing list to 1 year J The Microsoft Exchange Connection Status currently shows a 138ms average response on Mail, and roughly 2500ms on Directory Service. I think the Director service is horrid, but our ASP is blaming the white screens and poor response time on the size of our mailboxes. Ideas? So . how big is yours? == John == ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
