I have been using CRM for sometime with my main business email address. I recently wanted to switch my mail to Zoho mail so I set up an account. When I tried to create a user with the main email address, it wouldn't let me as it was 'already in use'. The online help told me to go into accounts.zoho.com and delete the address for there to free it up. I did this but now the CRM has switched to a different email address and the accounts are not connected. 

I realise there was some function for me to 'import' a user from other Zoho service but I realised this too late. Is there any way to fix this and connect the two Zoho accounts?

Thank you in advance!
