Just to clarify. I have only one account. this account is in my company exchange server. I download the Microsoft Exchange server account into my desktop when i am in office. when have to travel, which is often, i synchronise it with a cable to my pop3 account the pst from my desktop into my laptop. when i am away from my office, and mobile, i get all my emails in the laptop pop3. when i return to office and download emails in my desktop, ALLl the emails download from the Exchange server to my pst as read, even though i have not read some of the emails . so i am not able to figure out which ones i have read and which ones i have not !!!
