Flagging/reminders for mail in Outlook

Flagging/reminders for mail in Outlook

Hi,

I recently set up Zoho Mail in Outlook 2010 via IMAP.  One thing I use a lot in Outlook for my other non-Zoho account (Pop3) is setting flags with reminders for individual mail items.  However, with my Zoho account, it only gives me one option when I right click the flag icon ("Flag Message"), whereas for my non-Zoho mail it also shows the option to add reminder (date/time specific).

How can I get that feature working on my Zoho account in Outlook?

Thanks,
Tyler
