Clear The Outlook Name Cache


Active Exchange services, see Add Hosted Services. Properly configured Autodiscover record.



This article demonstrates how to clear the auto-complete cache in Outlook 2007 and Outlook 2010, and Outlook 2013.


It is possible for the auto-complete cache to become outdated, or incorrect in pointing to an old server address for an email. In that event it can cause email to be routed incorrectly, resulting in failed deliveries, and non-delivery receipts. By clearing the auto-complete cache, Outlook will seek out the email address anew with updated routing information.


Outlook 2013 Clear Name Cache Instructions:

1. Select File



2. Select Options;



3. Select Mail and Scroll Down until you reach "Send Messages"

4. Select "Empty Auto-Complete List"



5. A confirmation window will open up, then select "Yes"

6. Select "OK" to complete the process.


Outlook 2010 Clear Name Cache Instructions:

1. With Outlook 2010 open, either click the New E-Mail icon in the Home tab, or use the hot key Ctrl+N to open a new message.


2. Begin typing the email address that will be cleared from the name cache. After a few keystrokes, the email should appear below the To: field. Click the X next to the email address to clear the email from the Auto-Complete cache.


Outlook 2007 Clear Name Cache Instructions:

1. With Outlook 2010 open, either click File, then New, and select Message, or use the hot key Ctrl+N to open a new message.


2. Type one or more letters of the recipient name or address; this will show memorized (cached) entries in a drop-down list. Use the arrow keys on your keyboard to select the entry to be deleted. With the entry highlighted, press the DEL or DELETE key or your keyboard to remove the name from the Auto-Complete cache.
