Unable to create same email after migration to Zoho

Unable to create same email after migration to Zoho

Hi,
I recently migrated from hostinger email to zoho email. After verifying all TXT fields, I'm able to create new email ID and send/receive emails from this email. However, I'm trying to create the same email ID that I was using in Hostinger but I'm getting this error "Email Address already exists or associated in another Organisation".
I want to create the same the same email ID as earlier and complete the migration. Please help here
