Just came over to the Thunderbolt from an HTC Imagio. Loved the phone and had no problems with it...
until my work decided to changed from Exchange Server 2003 to Exchange Server 2010.
After this, my Imagio (Windows Mobile 6.5) and a coworkers HTC (Windows 6.1) both would not connect up to the new Exchange Server. We were the only Windows mobile phones. Everyone elses iPhones, BlackBerrys and Android phones all worked fine. Had no choice but to change phones.
The Thunderbolt connects up to the Exchange Server and my contacts and emails work great, but nothing from the Calender comes over at all.
I'm using the trial version of Touchdown to get emails, contacts, calender and tasks from the Exchange Server and everything seems good. I've got about 8 days left to decide on keeping the phone or going to an iPhone.
