Outlook 2007 and Exchange 2010 GAB

I recently had to make changes to a users email account which require me to delete the account on AD and on Exch and recreate it.

The users account was linked with a departments email address (department@domain.com), now when I try send an email to that department is get this error:


IMCEAEX-_O=DOMAIN_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=User+20Name@domain.com
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

This issue only seems to be appearing on certain users outlook accounts.

Any assistance is appreciated.

Outlook maintains a “nickname” list that is used by both the automatic name checking and the AutoCompletion features. The nickname list is automatically compiled as you address email messages. If the nickname cache becomes corrupt, Outlook may not be able to identify recipients, may offer incorrect recipients, may send to an incorrect or old email address, or may send the message to the wrong person.

If you are having problems with a single recipient, you can easily delete the one cached entry as shown in the following section, “Delete a single cached entry”. Otherwise, proceed to the section titled “To delete your Nickname Cache file” further below.

To delete a single cached entry
1.Open Outlook
2.Open a new message window; go to the File menu and choose New – Mail Message.
3.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.
This removes the entry from your autocompletion cache.

To delete your Nickname Cache file.
Use the following steps that are appropriate for your version of Microsoft Windows to reset the Outlook nickname cache. After you restart Outlook, Outlook generates a new nickname cache.
