# Add Share: "Key not found"

### Problem

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

![Error-Message: "Failed to open site: Key not found"](https://2727108687-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M8zLVuKYctMIUr68_fs%2Fuploads%2FADVvgl4tkDoWvLN5m9gy%2Fimage.png?alt=media\&token=7cfa3fec-cdb9-4be0-89ca-d7743316b1b2)

Customers with this issue may also also experience this: [libraries-are-empty](https://docs.konnekt.io/troubleshooting/causes-of-missing-content/empty-libraries/libraries-are-empty "mention")

### 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](https://docs.konnekt.io/installation/software-updates "mention").
