Duplicate, triple, quadruple ... email appearing in Outlook

Hi,

I have a strange problem related to Exchange Server.  

When I log on to the network with my laptop it downloads all of the email on the Exchange Server to the laptop and adds it to the email that is already there so now I have five times the number of emails on the laptop as there should be (maybe 5,000 emails when there shold be 1,000).  At the same time the laptop is loading up or maybe shortly afterwards the email on my PC all gets deleted so I have to go to Tools>Recover deleted items ... to re-instate my Inbox.

I don't mind the restoring of deleted items too much but I don't know what to do with the 5,000 emails on my laptop.  I am afraid if I delete them they will disappear off Exchange Server forever.    

What should I do?

Thanks,
merdeka

Also:

Microsoft has a support article about this issue (http://support.microsoft.com) Article #: 885870 - Duplicate e-mail messages are downloaded from a POP3 e-mail server account in Outlook 2003 and a fix:

885243 - Description of the Outlook 2003 post-Service Pack 1 hotfix package - September 13, 2004

You can also download a program from http://www.mapilab.com called Duplicate Email Remover which will identify and mark, move or delete duplicates messages that have already been received in Outlook 2003.

under your outlook profile, do you have more than one setting configured?
i.e is it using pop3 as well as an exchange connection?
