Nokia N8 Mail - IMAP Sync not deleting mails in ZOHO

Nokia N8 Mail - IMAP Sync not deleting mails in ZOHO

Hi,
I have switched phones and Email providers and thought all was going well until hitting a problem deleting emails from my Nokia N8 Mail.

Having added my Zoho mail account as an IMAP account all my mail was successfully retrieved. However, having deleted a couple of emils from my inbox I found they reappeared when new mail arrived. Looking into this further it would seem that my N8 cannot delete emails from my Zoho account even if I sync straight after issuing the request to delete the email on the phone.

Any ideas how I can sort this would be greatly appreciated.

Many thanks,
Adam
