Manually Update Your Local Copy of The Global Address List

If you are having problems sending to someone with a known good email address (such as a new employee, someone with a new e-mail address, or someone who has modified their TTU or TTUHSC email address), follow these instructions to resolve the issue. This is often caused when you are using Outlook in Cached Exchange Mode and the information that is cached is old and contains either incomplete or no information about the recipient.
