This is the setup
Mail Server running Windows 2000 Server and Exchange 2000. Everyone's mailbox is on the server and Ofiice XP (Outlook XP) is loaded and configured on clients machines to access there SMTP mailboxes'. Mail delivery occurs to there specific mailbox and we do setup and encourage people to copy important emails over to PST file (we setup the PST a file for the users on there PC) so that the size of users mailboxes on the server can be as little as possible and therefore free up resources.
This is the problem we are running into now. A top level management user (recieves a lot of mail daily) is having a problem opening Outlook (Office XP). When outlook is opened it seems to hang and a pop up box stating 'Outlook cannot connect to mailserver' appears with the options 'Retry' 'Abort' and 'Cancel'. Upon hitting the 'Retry' button it goes ahead, connects to the mailserver, opens outlook and the user can view there mailbox. This user has a very large PST file configured on there PC (it is so large becuase the user moves all important emails and documents and saves them onto PST file format therefore making the size of his mailbox on the server rather small).
Can any experts suggest a solution or an answer as to why this problem with Outlook not connecting to the mail server and only connecting after selecting 'retry' is occuring. I have loaded Win XP SP2 and configured the firewall setting to 'Off' as I have found in the past that this slows up Outlook. I have also thought about installing Office XP service packs but would rather not do so because in the past we have had the case that the service pack picks up when another program is trying to access the users address book and a very irritating pop up box appears stating 'Allow access for 10min, 5 min, 1 min' appears. Users get very fustrated which leads to them taking there fustration out on the IT department because there system is not running as smoothly as they would like.
Any suggestions on how to fix this mail server connection problem will be much appreciated.
Thanks in advanced
