I've built a patch that will allow your droid to sync with all exchange servers. I've disabled the check for unsupported security protocols. Full list of faked protocols: Device Encryption Password Recovery Password Expiration Password History Max Attachment Size Attachments Enabled (didn't know this was unsupported, it wasnt immediately obvious in the code but fixed now ) I want to make this clear: THIS WILL NOT ENCRYPT DATA ON YOUR DEVICE. It simply pretends to have the above protocols implemented. These are the only protocols that aren't implemented in froyo, so this should be able to sync with ANY exchange server. EDIT: 7-19-2010 This is no longer a full ROM. I've created a patch zip that should work on any rooted droid AS FAR AS I CAN SEE. This is a very lightweight patch, and simply changes the exchange portion of the built in "Email" package: http://onix-android.com/nicklipple/fake-unsupported.zip Also, I have made another version, same as above, but this will also eliminate all password requirements from your phone when syncing exchange (you can still choose to put a password on if you want, just not required) http://onix-android.com/nicklipple/f...ted-nopass.zip Download the .zip to your sdcard. Reboot into recovery, and choose "Install zip from sdcard"
