The List View Threshold Exceeds the Limit of Current Threshold limit in SharePoint

The List View Threshold Exceeds the Limit of Current Threshold limit in SharePoint:

 Issue: The List View Threshold Exceeds the Limit of Current Threshold limit.

Cause: The No of lists created in the site will be more than the Default Recommended value (5000) By Microsoft.

It’s not recommended to increase the List View Threshold above 5000 as recommended by MS. There may be some performance issues with the site occurs.

Workaround: Please find the below as Work Around to resolve the issue.

split the items into multiple lists so that no list exceeds 5,000 items. Because you'll be unable to view the list items beyond the limit of 5,000 items, you must configure metadata-based navigation so that you can access all the list's contents.

To enable metadata-based navigation, follow the "Enable Metadata Navigation and Filtering" and "Configure Metadata Navigation" sections of the following Microsoft website:

After metadata navigation is enabled, the list's contents will become available. We recommended that you then reduce the list's contents to less than 5,000 items.

Note: This is only for SharePoint 2010 and SharePoint 2013.In SharePoint 2016 The Limit is increased.
