Unable to add specific user or alias

Unable to add specific user or alias

Hi,

Just discovered Zoho and I love it!!! So thanks!

However, I am unable to add the user roger@ to the domain andreabartig.co.uk - I just get the error "the data you have entered already exists".

I have only added a single user so-far andrea@ and can find no reference anywhere to roger@

It seems I can add other addresses as expected.

Am I doing something wrong??

Many thanks,

Felix
