Greetings all -
Long time lurker, first time poster here. I have done some searching on this but I can't find a definitive answer. My company is looking to switch hosted Exchange providers. Currently we use T-Mobile (and I guess it is their BIS solution) and Mailstreet (with what I suppose is the BES service) to get my e-mails sync'ed to my 7290 in real-time.
We are moving to 1and1.com, and they don't have a Blackberry add-on service. So, can anyone tell me what my experience will be like if I use T-mo's BIS service and have it "pull" or whatever via IMAP, POP, or OWA (it appears 1and1.com supports all three types)? Will I still get real-time e-mail and be able to send mail showing it coming from my
