I currently have a ZOHO email account (free personal account) and one ZOHO email address. 

When setting up my account with ZOHO I was required to provide another active email address that did not exist with ZOHO to confirm my registration.  I see from the Q&A forum that this outside email address will be used for all future password resets and will always be associated with my ZOHO email address, and that is why my old outside email address is identified as my ZOHO "Email ID".

Here's my problem.  I am moving to an area where my old ISP does not  provide service and I will be forced to abandon my old non-ZOHO email address, which is also my ZOHO "Email ID", associated with my ZOHO email account.   What happens to my ZOHO email account/address?

(When someone picks up my old email address at my old ISP it will be associated with my ZOHO email account... which I do not want.)  

Please advise...
