Issues regarding email migration and mailbox size limit

Issues regarding email migration and mailbox size limit

Dear Zoho Team

Recently my company have migrated from Gmail to Zoho, however after migration, we realized that the capacity that was moved over to Zoho seems surreal. For example, my gmail storage amounts to 12gb, however i am using 22gb right now in Zoho after migration. I am unable to sort emails based by size either, is there a better solution to this?
