Hi All,I am migrating from Exchange 2000 to 2003.I have few clients running on Outlook Express- POP3 and SMTP configuration. Leave a copy option is enabled in outlook.When I move mailbox from Exchange 2000 to 2003, mails at mailbox gets download in outlook express and create duplication (Which are already downloaded).Can anyone tell me how to resolve this issue.Abhishek

Add the "created" column, sort by date and delete the duplicates.

Hi,Whether all the POP3 clients have this issue or just only the special user?Whether all the emails have the duplication when downloading?ThanksAllen

Yes, It is happening with all client.When I move mailbox from Exchange 2000 to 2003.Abhishek

Hi,Please check whether any error message was received in the Event Log, then post it on the forum.ThanksAllen

Hi Allen,There is not such / specific error.When I move mail box from Exchange 2000 to 2003, In Outlook express error appears that mailbox is not available b'coz I have moved it to exchange 2003. Now when I change IP address of Exchange Server in Outlook Express from 2000 to 2003, again it downloads all the mails.All events are informational. without any warning or error.Please suggest and Sorry for delay in reply.Abhishek
