If you have an email account on Microsoft Exchange and use Microsoft Outlook to send email, you might receive an error message if sending email to someone who has had their mailbox changed or removed from Exchange.  When this happens, the error message says "RESOLVER.ADR.ExRecipNotFound; not found ##" with a long email address in blue.

 

This happens if you have emailed the person before and the address appears in your auto-fill list stored on Outlook (also called an MK2 list).  If this happens, you can delete out the entry and try to resend the message. To do this:

  1. Start a new email message in Microsoft Outlook
  2. Start typing the person/department's email address in the To box.  A dropdown list should appear with the person's full email address.
  3. Press the down key to highlight the address, then press "Delete" on your keyboard.  The email address will disappear from the auto-fill list
  4. After the entry is deleted, type in the whole email address and resend the message.  The new entry will be saved in your list for next time.

 

An example error message is below:
