Well DUH . . . if you have events with no times right at the beginning of the list of events . . of COURSE the entire .ics file is going to fail . . . . remove broken events and everything is just fine . . . note to self -- pay closer attention!
Howdy . . . having a problem getting zimbra to recognize (guessing it is more a can't than won't 
) an .ics file as a valid calendar . . . . the .ics is created dynamically (coldfusion/oracle) based on a user profile. . . . the error message rec'd is:
Appointments could not be retrieved. Make sure the following URL is a valid ICAL feed: http://cfdevws01.imt.uwm.edu/employe...1-mabraham.ics
Any assistance would be greatly appreciated!
oh yeah. . .whoops . . forgot to include the code that creates the file content . . sheesh . . . . here it is:
