# Add Share: "Key not found"

### Problem

When you try to add a SharePoint library manually (see [Additional document libraries](/configuration/mappings/add-a-document-library.md#add-additional-document-libraries)), you get the the error message "Failed to open site: Key not found".

![Error-Message: "Failed to open site: Key not found"](/files/4UZnAkIknTQjexmoKw9H)

Customers with this issue may also also experience this: [All libraries are empty](/troubleshooting/causes-of-missing-content/empty-libraries/libraries-are-empty.md)

### Background

Microsoft (temporarily) changed the content of the response of the query for the library discovery for some tenants. Therefore KONNEKT will not map those affected libraries.

### Solution

We implemented a workaround for that behavior starting with KONNEKT V2.0.0. Please see here, how to get the update: [Software updates](/installation/software-updates.md).
