Previously entered email addresses not flushing.


We have just migrated our business mail and domain to zoho.
Everything is working ok except when I created the user "accounts@domain.com". I created the account and I then deleted the account because I had put some details in incorrectly. I have now created a new user accountsa1@domain.com and the problem is that I can't put the alias of accounts@domain.com in because it gives "account already exists" error. There is no record of this address in the domain or other users alias's.

I was wondering if the system took a while to clear deleted accounts and their details? I would also like to know how long it will take to clear this deleted account as customers will be recieving bounce messages for this account.
