Troubleshooting Portal Calendar View

[Frances1]

I'm working in a Power Apps Portal and need to create a calendar that uses data from Engagement Opportunity records. I have created a list specifically for this calendar and mapped some, but not all, of the fields (which are not required, so I'm not thinking this is not a problem). I'm using this documentation.

While I can see a calendar, I cannot see the dates in the portal that exist on the Volunteer Management side. There is a vague red ribbon error above the calendar:  'There was a problem loading data for this calendar.' 

My research is showing that people just go for FullCalendar using liquid, but since it is preferrable that we use this out of the box option, I'm wondering if anyone here has some recent experience with this error?

Troubleshooting

First of all we tried to fix the issue by moving the mailbox to a different Exchange database through the Exchange Management Shell. This usually helps to repair small issues within the mailbox database.

Unfortunately this didn’t fix the problem.

Next step was to create a mailbox repair request to see if this brings me to the final solution:

Nope, that didn’t helped, either.

The last thing we tried on the Exchange side was to start a calendar repair using the Shell, again.

First we had to check, how the schedule was configured. we then changed this setting with the following command:

After that we just had to enable the repair setting on the mailbox with:

So far so good… – NOT!! That also didn’t help.

From now on we changed my focus onto the Outlook client and the calendar items.
