can't send email to one user. Outlook 2010, Exchange 2010

I just tried to send from my account to a user in our company.  I get the message that the email is no longer valid.  see attachment.  Note in the attachment it is addressed to Danielle Sevier.  The message above has Danielle SeRvier.  different name.
The user is getting email.  I know because I logged on as her.

Her info. is correct in the Global Address Book and I also checked her properties.  See 2nd attachment.

How do I fix my Outlook?

Does this work via OWA? If this does then there should not be anything wrong with Exchange or the users mailbox. In Outlook if you use the GAL and manually add this user to your Outlook session can you send email to the user?

I think this might be due to nicknames/auto complete in Outlook. When you start typing the Name of the user click the "X" beside the name to remove it. Then re-enter the users address manually again or from the GAL (stated above). This should correct the issue if it is in fact working in OWA with no issues.

If you still cannot get it to work in Outlook you might want to create a new Outlook profile and try again.


This is definitely a Nickname/Autocomplete problem. I would go with the above suggestion and your problem should be resolved. This can either happen after an Exchange upgrade, or a typo, or when a user changes their name (after marriage, for example).

You can also try and edit the NK2 file (depending on the Outlook version), with this software:


The NK2 file is usually in %localappdata%\Microsoft\Outlook or Outlook\RoamCache

%localappdata% = %userprofile$\Local Settings\Application Data (XP), or %userprofile%\AppData\Local (Win7)
