Zoho Mail - Not updated with actions from N8

Zoho Mail - Not updated with actions from N8

Hi,
When I view my mail using the mail program on the Nokia N8 (setup as IMAP) it does not reflect my viewing or changes on Zoho. When I sync it brings all the mail back onto my phone as unread even if I have read it on the phone. I will also not delete from my phone even if I manually sync after every action.

Please help as this is holding me back from using Zoho on my phone.

Many thanks,
Adam
