Solution won’t help unless you know the reason behind Google Calendar on Android not syncing or Outlook for Android not syncing the calendar. There are various reasons why syncing problems can occur:

  • Poor internet connection: A weak or unstable internet connection can cause sync issues.
  • Battery saver modes: These power-saving features may hinder background sync due to energy conservation restrictions.
  • Outdated app versions: An older version of an app may not function correctly with the Android operating system.
  • Disabled auto-sync settings: Without auto-sync, calendars will not be updated.
  • Account permission issues: Calendar applications require authorization in order to fetch data and synchronize information between accounts.
