I have 4 email addresses on my blackberry, and for some reason I have lost all the messages in my blackberry older than a week, is there a way to reobtain the emails, especially the ones that went to my sprint.blackberry.net emails address, can i view those emails in a web browser.

You should be able to retrieve any that are on the mail server still, by accessing via PC, but any that are to the .sprint.blackberry.net are goone for good, as there is no other way to access these other than your BB.

Just out of curiousity, what is your file free under options>status?

Just access them on the mail server.

Welcome.

To consolidate from above if are on BIS (NOT using a corporate server) and the e-mails went initially to your sprint e-mail not forwarded to your sprint e-mail, then those are bye bye.

The other e-mails will be found on your PC

You may be having a memory size problem if you are losing them off your BB.
