Hi experts,

ok currently we have two servers. 1 win2k which is the dc/gc and ol exchange server with a few mailboxes still to be migrated (exchange 2000). One new bow with windows ent 2003 and exchange ent2003. I recently upgraded a number of users from outlook 20002 to 2003 (Using the upgrade option on the office 2003 disk) and then moved thier mailboxes. All went well.

two problems.

1. On some users when they try to open outlook they get the message "The exchnage server is not available, retry, abort or cancel", if they retry it connects fine. Ive solved this simply by recreating the profile and this seems to stop this, but why has this occured, is it it something to do with the upgrade process.

2. The important problem. It seems to take a good ten seconds for every user to open outlook and begin using it. Once outlook is fully up, it seems to work fine. This is not the case if the mailbox is on the old server, where it starts up almost immediatley. I havent fully finsihed the migration, so the puiblic folder, address book are replicating across from the old box to the new. I havent moved any of the exhcnage roles either onto the new box yet. I can ping both old and new servers, both ip and name, and the new box passed all the test when i installed exchange2003 into our organisation. Any ideas what is causing this, should it be expected, and if not, any advice on what/ how to tackle the problem

thank you for your help

Paul

Is outlook taking time to open for all users on the new server? Are you facing other performance issues also like, outlook takes time while you access folders in your mailbox like Calendar or Inbox?
Does outlook take time, when you try to access some Public Folders using Microsoft Outlook?
What is the status of Public Folder replication? have you added replicas for all your Public Folders ?

Try one thing, go to Exchange System Manager - Properties of the mailbox store on the new server and change the "Default Public Folder Store" - point it to the Public Folder store on the old server.

Close and re-open the Outlook and see, if takes the same time again. If not, then its Public Folder issue, make sure that your Public Folder hierarchy has been replicated successfully to the new server and then add replicas and wait for replication to complete from old server to new server. (you can use pfmigrate to add replicas)

Thanks,
Amit Aggarwal.

Hi,

Ok i changed over the public folders.....same thing. All public folders are in synch between both servers. There dosnt apper to be any problems performance wise once outlook is up and running, only when it is first being started up. This is the same for all users.

cheers

Here is a MS kb for Outlook 2002 for similar behavior, i would suggest you to try the same options in Outlook 2003 also.
Also, you can consider applying SP2 for Office 2003 and this update after that ->

Hi,

ok ive tried all the options, none make a difference. Ive also updated and patched office 2003, this dosnt seem to have made any difference either. In safe mode it dosnt seem to make much of a difference. Here is the strange thing, first time outlook opens it takes about ten seconds to come up with emails etc, and then runs fine. If i then close outlook and re-open it straight away it opens up almost instanously. If i wait say five minutes, it takes 10 seconds or so again (i know this isnt a massive amount of time to wait, but is much slower than what it used to be before the migration).

i can ping ip and fqdn to both servers no problem. Once outlook is running ive checked the connection status and outlook has connections to both GC and mail server with good response times (once outlook opens it runs fine). Could it be that its taking time to authenticate across the network (before the migration the exchange and GC where on the same server),

thankyou for your help

Is your Outlook 2003 running in cache mode? try configuring a profile without cache mode and then open it. does it make any difference.

Last thing, you need is Netmon. install netmon, start it to record traffic and then open outlook, wait for 10 seconds and then, stop the netmon and see whats all happening there. and you can compare the network traffic for users on 2000 server and 2003 server.

Thanks,

How many Global Catalog servers you have? if more than 1, check which GC is being used by your Outlook? is it correct? or you want it to use a better (nearest) GC?

Check these KBs -->

Hi,

We only have 1 GC. As for netmon, when the mailbox is on the old server, the client connects to this server (makes two connections and up pops outlook, within a second. When its on the new server, it still contacts the first server, waits, connects and then contacts the second server, waits, connects and then up pops outlook.

thankyou for your help,

cheers
