E-mail support with work e-mail

Question

Hello all Blackberry users!!  I got my blackberry Curve 8330 in April and recently my work has decided that it was against policy to have your e-mail go through a third party. Fair Enough.  Then they said people with Blackberry's will have to have their email deactivated because you have to sign up for BIS, which is an unsecure e-mail server that could potentially pose harm via our secure e-mails.
Well... when I did set up my phone in april, I didn't have a BES server and I didn't sign up for BIS.  I simply put in my e-mail and password and it found the webserver e-mail (https://....).  I was using it fine, even though messages would come in up to 10 min later.  
So here's the big question for me and the other 80 people who are confused, even though we went through and just put our e-mail address and got the proxy server via https and didn't sign into a BIS account with Blackberry, is it technically going through the BIS servers?  
I don't want to buy a new phone, I can't afford it and work doesn't care.  I don't want to do the wireless sync thing via laptop and have it push via a cable.  Any thoughts? 

Answer 1

if you put in a server address with "https://" then you integrated OWA, which is through BIS
example: https://companyname.org/exchange
if you touched the Email Settings icon on your phone, then you integrated through BIS
Here is some information about email security through BIS
1. Email messages and instant messages
Email messages and instant messages that are sent between the BlackBerry® Internet Service and your BlackBerry device use the security
features of the wireless network. Messages that are sent between your messaging server and the BlackBerry Internet Service are automatically
encrypted if the server supports SSL encryption.
2. Encryption of login information
When you log in to the BlackBerry® Internet Service web site using a browser on your computer, the BlackBerry Internet Service uses SSL
encryption to help protect your login information and any changes you make to your login information. This encryption is designed to protect
your user names, passwords, and other BlackBerry Internet Service account information from unauthorized access.
Email as a whole is one of the most unsecured portocols out there, The only way that your company could have secured emails is to only allow it on the intranet(internal tho the building) and not the internet(over the wide web). As soon they they expose their email to the internet it is unsecured, there is no encryption when sending over the web. It isnt possible for a BB to make it any less secure.  Might want to get some more info from your company IT department. BBs are one of the most secure devices out there.
There are 3 ways to get emails to a BB. BES, BIS, and Redirector(requires exchange, outlook and DTM to open at all times, does not support attachments)
