Exchange users e-mails going to an external recipient appear from IMCEAX-_o=XMAIL+OU=Exchange....
I have a user that all of her e-mail when leaving our Exchange 2007 environment the FROM/REPLY TO address gets changed to a IMCEAX style address. I can't find anything wrong with her mailbox, any suggestions on troubleshooting this? Her AD user object does have a \ character in the display name, CN and distinguished name. We're not sure how that got their so maybe just renaming the object will fix this. We haven't tried this yet as we don't control the AD objects, only the Exchange objects. Thanks, Jason Jason Meyer

Have you disconnected and reconnected this mailbox recently? Whats the behaviour in Outlook web access? If it works well in OWA then it something wrong with the outlook profile or config Have you tried to clean nk2cache file in outlook n then send a test email? http://support.microsoft.com/kb/287623 Lets open up outlook and click on new mail message Go to options and then click on Direct Replies to Check for option "Have replies sent to", See if it shows the correct name.

Hi That the IMCEA encapsulation occurs is telling you that there is no valid SMTP address for the user. 1. It is nk2 cache file problem 2. It is AD user problem. You cant control AD object. Maybe you can create new database and move it to new database. If it doesnt work, you can create X500 address for i. If it doesnt work, you have to modify or recreate AD account.

We found where one of our on premise identity management tools was messing up the legacy Exchange DN. We fixed that and the problem went away. Thanks for all of the other ideas/places to check for this type of error though. Thanks.Jason Meyer
