Let us use alternate libraries from the default "Documents"
Inside Onedrive for Business, we are currently able to go to "Site Contents" and add additional libraries, which currently works for integrations with other products such as Dynamics 365, however we have been told that alternate libraries inside OneDrive are being deprecated and will no longer be supported.
This decision to deprecate alternate libraries should be reversed for several reasons including the fact that it contradicts the existing limitations on the number of items that can exist in a single library.
Let us continue using alternate libraries inside OneDrive for Business, as we need this to continue being supported going forward. We have lots of data in these alternate libraries and loss of support and functionality there will be detrimental to our company.
