I cannot get Microsoft Exchange to work with my email/calendar at work, so I've set up an IMAP account for work email and it syncs fine. Now I wanted to set up a calendar on my Droid to sync with my work calendar. When I go into the built-in calendar on the Droid, it shows that I'm running 2 calendars, "Holidays" and my Gmail calendar. If I go into "settings" and click on "Add calendar" the option to "OK" is grayed out. Why is this? Is there a limit of 2 calendars? And if anyone knows, is it indeed possible to sync my work calendar into the Droid using IMAP? Thanks.
