Dear Team,

my domain is "winmacz.info" . I created 4 email addresses and they are working properly. im having requirement to create email address as " support@winmacz.info" for my organization support centre. 

when i create user as support and email as support@winmacz.info it is always prompting up an error as, given email ID already exists. but there is no such email address actually in my user list.

after getting this error, username is created in users list without email address. 

Please provide your support to resolve this issue. 

Referenced screenshots are attached herewith.

my oraginization admin email ID is " sales@winmacz.info"

Thanks 

Udayanga
