After upgrade to ver 14 we have one domain that gets this error.

See below for error.

 

I checked the accountlist.xml file but nothing duplicated there.

 

The error happens when you try to manage users.

Web mail gives you an error on the users page only.

Cant find anything that looks wrong.

 

Any suggestions?
