Disable Android Exchange Enforced Email Unlock Security

If you tried to load an entreprise email account in the Email.apk app and the Exchange server enforces a minimun password, it could be pretty annoying. To get around it, you can start by getting a modified version of the app from shafty023 onto your rooted phone. Copy the app to your SD card. Then run

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mv /sdcard/Email.apk /system/app/
chown root /system/app/Email.apk
chgrp root /system/app/Email.apk
chmod 644 /system/app/Email.apk
reboot
