Calendar Feed: Date Format Influences Visibility in Outlook?

[G_Petruzella]

Context: When using the *.ics URL from Canvas Calendar, faculty have noticed that some events do not appear in Outlook's calendar. In examining the *.ics sourcefile, I believe I've discovered a correlation:

Events successfully appear in Outlook when their DTSTART and DTEND fields are formatted as follows:

• DTSTART:20211021T150000Z
• DTEND:20211021T180000Z

Events fail to appear in Outlook when their DTSTART and DTEND fields are formatted as follows:

• DTSTART;VALUE=DATE:20211020T000000
• DTEND;VALUE=DATE:20211020T000000

My 3 questions to the community:

1. Has anyone else encountered this problem with Outlook Calendar? (Google Calendar seems to handle things just fine.)
2. Has anyone else noticed the above correlation, or is there another explanation?
3. Has anyone got a ready fix? 🙂

Hey,

I am also running into problems with the ics file containing: DTSTART;VALUE=DATE:20211020T000000.

I get an IOException parsing error when this occurs in the ics file.

I am using java and the ical4j library to parse the ics file.

I have also noticed this occurs when there is not a specific time assigned to a calendar event.

Has anyone found a solution or work around?

Thanks, Jerry
