When I overlay calendar within a site collection, it works as expected. However, it won't work across site collections giving the error: Unable to find specified web in the given URL.
In addition, I notice that the post was 3 years ago and it applied to SharePoint 2010. After doing further research on MSDN forum and Technet form, I find that there is an issue about SharePoint 2013 calendar overlay across site collections. Here are the links for your reference:
Hi,
ReplyDeleteI faced the same problem when I imported Calendar template in other web application.
To resolve the issue, After adding Calendar from custom template I deleted all the calendar overlays then recreated again same overlays with correct website URL.
Now problem is resolved and data is also fine.
