Outlook name cache file not updating
Outlook provides a Use Auto-complete List to Suggest Names checkbox, which should be selected (Figure 1).
Next, do a simple test to determine whether the Outlook 2013 auto-complete list could possibly be corrupt.
The Global Address Book (GAL) is a directory of available contact information for CUMC, NYPH and Columbia University faculty, staff and students.
It can be accessed when using a CUMC email account with Outlook and Web Outlook.
NK2 file, it's stored as part of the mailbox and replicated to Outlook.
Open Outlook and type the first few characters of a recipient's name.
If Outlook doesn't attempt to automatically finish the name, click the Check Names button.
If an add-in causes Outlook to crash, the auto-complete list could become corrupted or new entries might save to the list, depending on the nature of the crash.
You can manage the list of add-ins by clicking the File tab and then clicking Manage Add-Ins.
