This happens on our site too. Ususally just means they have been auto created as a user on the RT instance when emailing through a request. In the Web Interface instead of creating a new user just search for their email address and update the existing user. <br>

Hi all,<br>
<br>
I've been adding an managing users through RTs web interface without<br>
problem. These users have all had email ID's<br>
of the form <username>.<a href="http://dept.univ.edu" target="_blank">dept.univ.edu</a><br>
<br>
Recently, we've had to give RT access to personnel from central campus<br>
who have email ID's of the form <username>.<a href="http://univ.edu" target="_blank">univ.edu</a>. However, trying<br>
to add these users returns the following error:<br>
User <username>: Email address in use<br>
<br>
I am running version 3.8.1 with mySQL DB backend. The following<br>
appears in my RT_SiteConfig.pm<br>
------------------- start code<br>
----------------------------------------------------------<br>
Set($WebBaseURL , "<a href="https://rt3.dept.univ.edu" target="_blank">https://rt3.dept.univ.edu</a>");<br>
Set($rtname , "<a href="http://dept.univ.edu" target="_blank">dept.univ.edu</a>");<br>
Set($Organization , "<a href="http://dept.univ.edu" target="_blank">dept.univ.edu</a>");<br>
------------------- end code<br>
----------------------------------------------------------<br>
<br>
<br>
1) In the file $RT3_INSTALL/lib/RT/User_Overlay.pm<br>
------------------- start code<br>
----------------------------------------------------------<br>
#SANITY CHECK THE NAME AND ABORT IF IT'S TAKEN<br>
if ($RT::SystemUser) { #This only works if RT::SystemUser has<br>
been defined<br>
my $TempUser = RT::User->new($RT::SystemUser);<br>
$TempUser->Load( $args{'Name'} );<br>
return ( 0, $self->loc('Name in use') ) if ( $TempUser->Id );<br>
<br>
return ( 0, $self->loc('Email address in use') )<br>
unless ( $self-<br>
>ValidateEmailAddress( $args{'EmailAddress'} ) );<br>
}<br>
else {<br>
$RT::Logger->warning( "$self couldn't check for pre-<br>
existing users");<br>
}<br>
------------------- end code<br>
----------------------------------------------------------<br>
and<br>
------------------- start code<br>
--------------------------------------------------------<br>
=head2 SetEmailAddress<br>
<br>
Check to make sure someone else isn't using this email address<br>
already<br>
so that a better email address can be returned<br>
<br>
=cut<br>
<br>
sub SetEmailAddress {<br>
my $self = shift;<br>
my $Value = shift;<br>
<br>
if ( $self->ValidateEmailAddress( $Value ) ) {<br>
return $self->_Set( Field => 'EmailAddress', Value =><br>
$Value );<br>
} else {<br>
return ( 0, $self->loc('Email address in use') )<br>
}<br>
<br>
}<br>
------------------- end code<br>
----------------------------------------------------------<br>
<br>
Help much appreciated,<br>
