Shared Calendar Not Updating Outlook 2025 Automatically

Shared Calendar Not Updating Outlook 2025 Automatically. We've made major updates to the way outlook for windows connects to and updates shared. If your shared calendar is not yet on the new sharing platform in microsoft 365, you can upgrade the shared calendar manually.

You would be better off using a sharepoint calendar or a teams calendar for this. Enable “turn on shared calendar improvements” in the calendar properties.
