Ian, I have been trouble-shooting "requesting data from exchange server ..." problems for awhile now on a Windows 2000 SP4 / Exchange 5.5 SP4 enterprise edition server. There are many support articles that address the requesting data - slowness issues on an Exchange server. MS support has been helping diagnose (we have a contract) the problems. There have been two now that have seemed to help our situation and I am working on another in hopes that it will totally eliminate the problems causing our difficulties. I would like to share the one that has seemed to make the most difference so far. It has removed the instances of anger causing delays of many minutes which were occurring frequently, and we are now dealing with minor 7 to 15 second pop-ups. It is Anti-virus scanning attachments related and this is the url, http://support.microsoft.com/?id=264731. It talks about creating a registry entry, but reviewing the setup of the AV for Exchange software that we are using, I found a parameter setting that created the entry. It enabled attachment scanning in the background. That made a huge difference. Our mail store is much larger than the one you mention and mailboxes are much larger too. It may not be your problem. Good luck.

Up until a few weeks ago one of our SBS servers was working with Outlook fine. We would get an occassional 'Outlook is requesting data' pop-up, mainly when working away from the office using RPC over HTTP. Now it is happening far too frequently, and it locks up Outlook for the duration. This happens: * in and out of the office * in cached mode and also in 'not cached' * using RPC and RPC over HTTP After some research this is what I have found out * The pop-up specifies the FQDN of the server so looking here: http://tinyurl.com/9jnmc it makes me feel it could be a Domain Controller problem not an Exchange one. * Monitoring the counters listed in this article: http://support.microsoft.com/?id=839862 indicates no issue with RPC request being fulfilled. RPC requests and RPC ops/sec are low. It is only the RPC Averaged latency that rises during the time when a pop-up is occuring. * Again from the above article there are no other issues that have recently changed (the only add-ins being used are the standard ones etc.) * Sometimes all clients in the office are affected simultaneously other times only 1 at a time. * Mailboxes are all less than 400MB and most less than 200MB, total store is less than 10GB. Less than 15 mailboxes (only adding 1 every 6 weeks or so max) * When monitoring the general performance of the server it's CPU (1100Mhz (with 1GB RAM)) generally runs at less than 20% but sometimes the CPU will run flat out 100% for about 2 or 3 mins. At the same time 1 or more Outlook clients have the pop-up. (When the CPU is running at 100% for some other reason (e.g. spooling a big print job) all Outlook clients runs fine.) * Using SysInternals Process Explorer pins down that there are 2 processes that divide the CPU between them when one of these 100% runs is happening: WMIPRVSE.EXE running under 'Network Service' SVCHOST.EXE running under 'System' * running Trend ScanMail monitor shows that it is not dealing with incoming email viruses at the time. So ... I am now a bit stuck what to do next. I could run a network monitor or Ethereal trace to see what is happening with the traffic but I don't think I know enough to understand what to do with the results!! We have a 100MB switched network with usually less than 6 PCs active so I can't see it being a network problem. Also it is possible to be surfing the net or working on mapped drives while waiting for Outlook to sort itself out. (These are not the cause of the Outlook pop-up which usually seems to occur when using Outlook exclusively e.g. reading mail). Has anyone else had this sort of issue? Could it be a recent patch? The SBS is fully up to date with all OS and App patches inc. Exchange SP2. There are no third party tie-ins to Exchange except Trend ScanMail which is CSM 4 SMB v2 and has been untouched for months. Hope someone can help!!
