Sync issues null object must have a value

Hi,

There was a problem with the Outlook/Office365 synchronisation that started recently. It started to give errors with a message like "Nullable object..."

We have investigated it and it seems Microsoft created a bug in their public Outlook API.

We have created a fix/workaround in the software, please update to the latest OneCalendar version from the store to resolve this issue:
- Windows OneCalendar version 2023.310.1.0 or higher
- Android OneCalendar version 4.3.5 or higher
- iOS OneCalendar version 4.4 or higher
- macOS OneCalendar version 4.4 or higher

Sorry for any inconvenience.

Have a good day!
