What you could do is set up a rule in outlook that autoforwards any emails from
[email protected] to a gmail account and set up the gmail account on your bberry. This gets a little messy though because the emails hitting your bberry will be coming from
[email protected] to
[email protected] so you won't be able to preserve the original from/to, which makes replying to the email difficult/ugly.
You could also create a gmail account and give that address to the company that you need to converse with quickly.
Using BIS for work or timely emails is tough, I use it only for personal email, and BES for work.
