I have just set up IIS with ActiveSync on Windows Server 2003, running Exchange Server 2003. It is the only server, doing both the frontend and backend services. Now I can push mail to my Droid II using ActiveSync. This is the only device that has been connected so far, but I may add an iPhone later.
Next, I installed MobileAdmin to see if I could use the Remote Device Wipe option. It seemed to install correctly, and I can pull up the site in my browser. However, when I enter the mailbox name or smtp address in order to look up a list of devices, I receive the error message: "Could not locate the specified mailbox, verify that you entered the correct mailbox name." I have tried a hundred different times with different variations of my name and smtp address, to no avail.
There does not seem to be a lot of help available online about this error, so any comments on this would be appreciated.
