RE: Outlook slow to communicate with 5.5 server - long
re: SP4 on Windows 2000 I connect from home via VPN (over a DSL connection) to our Exchange 5.5 server using Windows 2000 and Outlook XP. Before applying SP4, I often had the 'requesting data' message and deleting batches of emails from my Inbox would take some time. Since applying SP4, this has definitely improved for me. Just my experience, but it is probably worth a shot.

RE: Outlook slow to communicate with 5.5 server - long
Well, over the weekend I did a bunch of work it may turn out I didn't need to do. The user had told me he did not have the IM support turned on when what he really meant was that he did not remember turning it on. But he did not actually look even though I told him where to look while he was on the phone with me. When after running all the tests below, I finally got to where I could see his client, he did have it turned on. I turned it off but didn't really see an immediate improvement. Today he says it is working better. We seem to have some other issues today though so I am not completely convinced. Over the weekend I did do a number of things, I ran eseutil /g which reported no errors as far as I could see. There were many lines indicating it was checking something but none indicating it had found a problem. Nor any indicating it hadn't. I also ran isinteg in check only mode. The results of the isinteg run (appended) show the only thing I could see that could possibly be a problem and I have no idea if it is one or if it is how best to get rid of it. I'm not feeling much like running isinteg in fix mode unless that is the only option. I reapplied SP4 and hotfixes to no observable benefit. I also ran performance optimizer but still had the problem. That was about when I discovered he had not actually checked to see if IM support was checked. So I unchecked it. I'm planning on stopping here unless someone says I should do something about the results of the isinteg run.

RE: Outlook slow to communicate with 5.5 server - long
Planning to run SP4 asap. It is only the one user though so I am not doing it until the weekend. Other users with Office XP had noticed the little message box but the delays were slight (under a couple of seconds or so) and for them the registry change fixed it right up. IM Messaging thingy huh? I'll check for that. It certainly isn't on in the Outlook 2000 client I tested with. Ronni * ..sittin' here on the Group W bench...

I looked over the command line switches documented in article 296192 but I don't see anything there that looks likely to help. I looked over the fixes in SP4 for Exchange 5.5 and I didn't see anything there although, I will apply that this weekend. I am at a loss for where to look next. Other than to look at isinteg checks and possibly exmerging his box out and in again. Which scares the bejeebers out of me. Since I have completed all but deleting the old Exchange server from the site I thought I should perhaps do that first but if that were the root cause it should affect more than just the one user should it not? Any help or pointers would be gratefully received. Ronni [1] He is on the lan not over VPN
