Error when trying to add Office 365 Calendar


I update our FreePBX 13 to FreePBX 14 and I’m getting this error when I try to add an Office 365 Calendar

The message appears when FreePBX is attempting to load the calendar list (after I click autodetect)
I tried to look in the different logs but I didn’t find anything.

Any ideas or leads ?

I just tested this and it works

Make sure you copied the ICS link and not the html link
Also make sure you are adding an ICS calendar

Thank you for your answer.

Actually, i didn’t add it as an iCal calendar, I chose Remote Outlook. I typed in my Office 365 user and password and the EWS Server URL was correctly detected.

If I have to chose an ICS calendar (which I will try tomorrow), what does “Remote Outlook” mean ?

You’d don’t have to chose that. James is just giving you another option.

“Internal Server Error” is coming from the EWS Outlook server.

I just went through this process with an outlook remote calendar and it worked without error.
