Hi, I have a HTC Desire (updated to Froyo) and have been syncing my contacts with my Outlook 2010 (running Windows 7 Enterprise - 32 bit). Everything seems to synchronize well but somehow the "email address - Display As" fields gets updated in outlook, which then doesnt allow me to send emails to those email addresses unless I manually go and update the display as field inside my outlook contacts. I have manually updated all the contacts once already hoping that it may not be due to HTC Sync but when I did the sync then immediately all my Outlook email ids got updated. Now everytime I try and send an email I immediately get Undeliverable receipt from System Administrator stating the following: Your message did not reach some or all of the intended recipients.
