outlook 2003 performance

Hi,

We have recently upgraded from exchange 2000 to exchange 2003 and from outlook 200 to 2003. We have one w2k server as the domain controller, and 1 2003 ent server as the new exchange server. When first opening up outlook, it takes alot longer in 2003 than it did in 2002, and overall the general performance of 2003 seems to be that little bit slower. Most of the PC's are always connected to the network, so dont run in exchange cached mode. Would making themr un in exchange cached mode help increase performance. Is there any other twaeks i can use to squeeze more out of our setup?

thankyou for your help

Cached mode would probably help the startup issue, cause outlook opens immediately and then updates as it gets information from the server.

You might want to check your DNS settings and make sure the primary resolver has the correct information for the new server ping by netbios name, etc. also if this is an upgrade was the old exhange server properly decomissioned, if not it could poiint to some other things.

Hi,

DNS seems ok, i havent yet fully de-commisioned the old server as ive still a few mailboxes to finish moving over, would this also lead to some slowness?

cheers

As an experiment, what performance like for Outlook 2000 users with mailboxes on an Exchange 2003 server and vice versa?  I am wondering whether it's a network issue with the new server.  Have you started backing up the new server yet?  If so, do you back it up locally or use Backupexec, etc... with a remote agent?  If the latter, how does performance compare to the old Exchange server?

Hi,

On 2000 it takes about the same amount of time on the new server, only it comes up with the message "retrieving information from exchange server". On the old server both 2000 and 2003 are more or less instantaneous. Im wondering wether its taking this time to authenticate across the network, as previously the old exchange was installed on the GC, now it isnt, or possibly that some of the exchange roles have not yet been moved over to the old server (such as routing master etc. As for backups i use veritas 10d. The backups are much quicker using the new server etc than the previous server.

cheers

I doubt this would cause a problem.  If there were authentication or resolution issues, then I'd expect these when you start up Outlook.  The fact you are noticing generally slower performance would indicate a general performance issue.

You didn't say whether you were backing up locally or over the network.

On another note, is the server plugged into a managed switch?  If so, how are the ports set?  Are you using teaming on the new server?  If so, what teaming mode.  Are you using the latest drivers for the NIC or the OS installed?

I just have a hunch that this may be a general performance bottleneck.

Could be,

The backups are done both locally (the mailboxes ive already moved) and over the network from the other server, but are run at night time after everyone has gone home. The swithces are unmanged gigabit switches. The server is using two nics teamed together for fault tolerance. Outlook does take a little while to start up, and is only marginally slower than the old whilst running.

cheers
