Unable to map 2 shared drives using separate credentials

Environment Setup
I am running and Windows 10 Desktop Client and trying to connect to 2 separate shared folders create on the same remote server which runs on Windows Server 2008 R2

The Server has the following partitions:
C: (Root OS Windows)
E: Data drive

On the E: Drive I have created 2 folders:
E:\Data\Folder1
E:\Data\Folder2

I have Shared the Folder1 and Folder2 as \\Servername\Folder1 and \\Servername\Folder2
I have granted:
> Shared permissions to Administrators Group (full) and Everyone Group (full)
> File system permissions granted to Administors Group (full), User1 (full) for Folder1 and User2 (full) for Folder2

Task/Activity resulting in Error
When mapping the drive to a drive letter on the Windows 10 client I am only able to successfully map one Share at a time
After sucessfully mapping
\\Servername\Folder1 using User1 credentials to Drive Z on the desktop
Second mapping to \\Servername\Folder2 using User2 credentials fails with this error:
"The Network folder specified is currently mapped using a different user name and password.
To connect using a different user name and password, first disconnect the exitising mapping to this network share"

Require advise to resolve.
