From address in personal inbox

From address in personal inbox

Hello,

I have set up a personal inbox in Teaminbox via email forwarding from my Zoho Mail account.  I would like to use the email address of the team as from address in my personal inbox, but can not choose it and cannot create it as personal sender address, as it says it already exists. In Zoho Mail choosing the group sender address for personal emails is no problem. Help would be greatly appreciated. Thank you.
