I recently upgraded to BIS 2.3 and notice that my email sent from my BB (on my Yahoo account) are reconciled with my Yahoo sent box. Not so with Gmail. Is there a setting that will accomplish this, or is it a limitation of the Gmail account?

More then likely a limitation of the GMail account. It's more of a limitation between BIS and the mail system in question really. RIM really needs to improve BIS and the Internet Browser on the BBs if they want to stay ahead of the pack.

Who do you feel has better options than BIS for email integration?

Took the words right out of my fingertips...

If it's not doing it with Gmail, you can just have Gmail foward email to your Yahoo. Then it's all set

On another... the Sent emails from my BB show up in the Sent Folder in my Yahoo. But when I send an email from Yahoo, it doesnt show up in the BB. Is this expected behavior?
