Exchange 5.5 and slow Outlook connection

By mmolina ·
We have 12 remote users accessing our network for applications and e-mail. The NT server is running NT4.0 SP6a with Exchange Server 5.5 Sp4. When our remote users connect to exchange via Outlook, it can take 30 minutes for Outlook to open. Is theresome setting that I can tweak to allow our users to access there mail more quickly.

I also have OWA installed but they don't like using it because of functionality. Any and all hel would be great.

Thanks,

Mike

Exchange 5.5 and slow Outlook connection

You say remote users. What kind of connection are they using?

A couple of places to check.
Outlook->Services->Exchange Server->Advanced Tab, do they have encrypt all network traffic?

Outlook->Options check their offline folder settings.

This should be the way they are connecting.
Set the clients to startup offline, when and then set the synchronizations time outs and the mail downloads to whatever time seems reasonable. The user can initiate a download or upload by hitting F5 or send and receive.

Other places to look would be what kind of bandwidth are you using?

How many people are local users and using bandwidth?

Are they using an application at the same time they are opening outlook?

What type of application are they using?

You would be surprised by the amount of bandwidth on application can use if it was not designed to run over slow-bandwidth. Alot of applications are designed for LAN speeds not WAN or RAS speeds and can choke a line to a trickle ofexpected bandwidth.

Let me know about the questions I raised and I can answer more specifically.

Hope this gets you started in the right direciton.

The only solution to offer would be to implement offline folders. When they come into a office with WAN connectivity, setup the offline folders and do the initial synchronization. Then have the users start their outlooks offline, when they want to check mail or send mail, they can click on the send and receive button to get mail.

Do you use WINS or DNS for your dialup users?
It sounds (as maybe a different problem) as if it is trying to find the servers address and only at the end of (dns lookup, host lookup, wins lookup, lmhosts lookup, broadcast) name resolution does it connect and then it has to down load all of the server information.

Let me know if the helps you any?

Our remote users are connecting via dial-up 33-56k and are located all over the world; Hong Kong, Ireland, London, South Africa... They do a lot of traveling so dial-up is our only solution for them at this time. I've tested the connection time between Outlook open by itself and other applications open. It takes approx. the same amount of time. I'm not currently using the offline function but will try and see what happens when they try to send and receive. The other applications that our remote users use, which are proprietary to our company, run fine. Outlook is our only problem child and I wasn't sure if there was a tweak here and there within Outlook and/or Exchange to speed up the connection. Once the users are connected it runs fine, it's just the initial connection.

Any additional information would be great.

Thanks,
Mike

They are getting these delays because Outlook is trying to synchronize the mail folders on the laptops with those on the server. Have the users keep their mailboxes trimmed down to eliminate anything that's not important. Even important items can besaved as rtf files on the hard drive outside of Outlook. Have them use just the default folders and not to keep too many attachments there.
