Problem

When you try to create a calendar overlay in Microsoft SharePoint Online by using a calendar from a SharePoint Online subsite, you receive the following error message:

Sorry, something went wrong

An unexpected error has occurred.

Solution

To fix this issue, remove the ampersand (&) from the site that contains the calendar from which you want to create the calendar overlay. To do this, follow these steps:

  1. Browse to the site that contains the ampersand in the URL.
  2. Click the gear icon for the Settings menu, and then click Site settings.
  3. In the Look and Feel section, click Title, description, and logo.
  4. Remove the ampersand (&) from the Web Site Address field, and then click OK.
  5. Create the calendar overlay by using the new URL.

Note

  • To change the URL while at the root level of a classic or Modern site, you must change the site address. For more information, see Change a site address. (Note that navigation on a Modern site is not shown by default.)
  • The title, description, and logo settings page can be accessed directly by browsing to https://contoso.sharepoint.com/web1/_layouts/15/prjsetng.aspx (where "contoso" is your website).

More information

This issue occurs when the site that contains the calendar that you're creating the calendar overlay from contains an ampersand (&) in the URL.
