I've had my 8900 for about 2 months now.
When I delete SENT emails, "mailbox & handheld" button on my BB they do not delete in my sent folder in my yahoo account, why is that?
I remember when I first got my BB it did delete them.
So I always have to go in email account manually and delete the messages in my sent folder.
I tried removing the battery but not working. Deleting emails in my inbox works fine using my BB.
