No Calendar events with EWS Calendar

Hello everyone,

I have a problem with my EWS Calendar synchronisation.

I can set up the EWS Calendar on my FreePBX, it also show the different Calendars from that user.
But when I add an event, it doesnt show up in my calendar view.

The complete setup of a calendar works fine. Only the events are missing.

All Modules are up to date and I tested on 2 FreePBX 15 Systems.

Can anyone help`?

Update:
Same Problem on a FreePBX 16 System

Update2: Seems like a Exchange Problem. Another Exchange Server is working fine

A test with a EWS Test Tool shows no errors and it can read the calendar entries.

Seems like that the FreePBX isnt reading these items

Solved:

Adding

‘(UTC+01:00) Amsterdam, Berlin, Bern, Rom, Stockholm, Wien’ => ‘Europe/Berlin’,

At the /var/www/html/admin/modules/calendar/vendor/om/icalparser/src/Windows Timezones.php file, solved it.

Is there a way how I can make a pull request for that?
