Email to HSC users bounce. The email address has the address format of "firstlast@unt.edu" (IE, johndoe@unt.edu).

This was caused when we updated all HSC contacts with phone number and job titles. The problem was quickly identified and resolved. However, HSC contacts that had been cached by Outlook were modified to have the invalid email address format.

If the problem is only with one or two addresses, create a new email and start typing the users name that has the invalid address associated with them. When outlook tries to autocomplete the address, select the address from the drop-down and delete it.

If the problem exists for a lot of addresses,  the simplist fix might be to delete Outlook's contact cache.  To delete the cache, do the following:

• Open a window and enter the following in the address bar: %userprofile%\Application Data\Microsoft\Outlook
• Locate the outlook.nk2 file and rename or delete it.
