I did get a response back from HTC support. My question was stated as "My IT department won't approve the use of the Verizon Droid Incredible phone without verification that remote wipe is supported through Microsoft Exchange Active Sync. Can you confirm that remote wipe is possible through Exchange Active Sync for the Verizon Droid Incredible."
The reply answer was given as "The HTC Incredible does not include full security support - its hit or miss. We have tested remote wipe on various devices, including the HTC Hero and Droid Eris. Some devices will wipe while others won't. This is due to the lacking full security support on the Incredible. You may order the device and see if it can be remotely wiped by your server. If not, Verizon Wireless does offer a 30 day return policy on their devices. I would check with them for details."
On the surface, it seems like there won't be any better Exchange Active Sync support on the Incredible based on the reply. Now why their own people don't know what is or isn't supported on their phone still baffles me. I just can't see a lot of us that can choose our corporate phone want to go through the hassle of buying the phone and have their IT department "just try it out and see if it works".
