  • Can we create Calendar Overlay from Pnp Powershell in the sharepoint online sites?

  • Olivia, I have run into the same issue. Did you find a resolution? I am just adding overlays to act as codes for Travel, Work for Home, PTO, and Events.

  • Hello there, I have been using this feature for years on our SharePoint sites. This issue is that I can’t find the option nor a similar solution on the Modern SharePoint Pages. We need to migrate our sites to the new layout.

  • It may be an error because it’s not in the same Site Collection as the Calendar overlay.

  • Thank you for this helpful article!

    Is there a solution if the user is met with an error “Unable to find lists with calendar view in the specified web” or “Unable to find specified web in the given URL” when clicking the Resolve button?
    I’m trying to create a main calendar that features overlays from other teams’ calendars within SharePoint, yet these error messages persist whether I leave the default URL or insert the URL from the other teams’ calendar pages.

    Thank you!
