After I'm closing my E-mail outlook express. It alert the message that It need to compact to free up the disk space. After that I lose some of my E-mail message so how can I cam back my e-mail.

Please help me

Outlook Express had a limit on mailbox size as did earlier versions of Outlook. I had a similar problem several years ago and never got the mail back. I eventually improted into Thunderbird It let the mailbox get bigger but fell short in other areas. I heard Thunderbird is a lot better now. I eventually switched platforms all together and now like my PIM
I will follow this questin because I would like to know the answer after all these years.
