If your Microsoft calendar is not displaying all recurring events for a specific date range on your mobile device, you can take the following steps:

1. Check your email: Make sure that the emails from Microsoft Calendar are delivered to your primary inbox or the spam or junk folder.
2. Check the app settings: Review the settings in the Microsoft Calendar app to ensure that you have correctly enabled synchronization.
3. Check your calendar view: Make sure that you are viewing the correct calendar or calendars; filters might be removing certain events.
4. Check your device settings: ensure that the device settings are correct with respect to regional settings, time zones, and automatic adjustments for daylight savings.
5. Check your internet connection: If you are using a cellular connection, make sure you are receiving an adequate signal.
