Hi,

I regularly receive .ics files but when I try to import them into Outlook 2010 (64-bit) I receive the error message, "the file webinar.ics is not a valid Internet Calendar file".

I have tested one of these files by editing the contents and I have found that the following two lines are causing the problem:

Code: 
EXDATE;TZID="Pacific Time (US & Canada)":20120921T130000,20120922T130000,20120923T130000,20120924T130000,20120925T130000,20120926T130000,20120927T130000,20120928T130000,20120929T130000,20120930T130000 
 
RDATE;TZID="Pacific Time (US & Canada)":20120927T130000,20121004T130000,20121011T130000,20121018T130000,20121023T130000,20121101T130000,20121108T130000,20121115T130000,20121120T130000,20121129T130000

When edited like below, the .ics file opens up correctly:

Code: 
EXDATE;TZID="Pacific Time (US &  Canada)": 
 
RDATE;TZID="Pacific  Time (US &  Canada)":

The series is incorrect, but I'll look at that afterwards.

Is there a setting in my Outlook 2010 causing the original file to fail?
 
No, there is not a setting in outlook that needs changed. Outlook doesn't like the dates - recurring events should be use frequency rule:

Code: 
DTEND;TZID="Eastern Standard Time":20120928T160000 
 
DTSTAMP:20120923T043924Z 
 
DTSTART;TZID="Eastern Standard Time":20120928T150000 
 
LAST-MODIFIED:20120923T043924Z 
 
PRIORITY:5 
 
RRULE:FREQ=WEEKLY;COUNT=10;BYDAY=MO,FR
