Can't publish "Calendar" under "My Calendar"

Godofred_, your workaround worked like a champ! Thank you very much!

I tried that but did not receive an ICS and the XML file did not contain one. There is an accept link in the email, but it is not an ICS, and when clicking the link, I get an error 500.

How did you obtain the ICS in your experience?

I found a temporary workaround!

1. You can select "Share a calendar" instead of "Publish a calendar".
2. Put your e-mail address to receive the sync URLs. Select "Can see all details" if that works for you.
3. You will receive an e-mail message containing two files, but they actually do not matter.
4. On the e-mail body there will be a bunch of random numbers and letters, followed by an URL ending in .html, and then an URL ending in .ics. Use one of these URLs just as you would if you had published the calendar.

Just be sure to copy only one of the URLs and nothing more (I accidentally copied both URLs, believing it was just a big one, and it gave me an "Invalid URL" error).

In my case, I used the .ics URL to sync my Office 365 calendar with my Google Calendar, and it worked, so it should work for you as well (at least until Microsoft solves the issue).

Good luck. I hope it helps.

My invite to share did not have URLs but just GUIDs. Thank you!

It does, check here:

Mine does not have the option for a URL - nor is there a URL in the attachment.

I have the same problem. Unfortunately the identified workaround did not work for me.
