Local Folder Not exist – OneDrive Migration

So I have been playing around with the SharePoint Migration Tool trying to perform a OneDrive for Business migration from a local file server. During the setup of the migration in the SharePoint Migration tool, I got some errors which stated Line#1, Local Folder Not exist… for all the different lines:
Local Folder Not exist

In my case, It seemed like the path I placed in the CSV file, didn’t work for the SharePoint Migration Tool. Instead of setting the path like this:

\\FILESERVER\HOME$\username

I had to change it to include the disk name “C$”, like this:

\\FILESERVER\C$\HOME\username

I spoke to representatives from Microsoft about this, we didn’t conclude but they believed it to be caused by the dollar sign in the shared folder “HOME”.
Although it don’t seem too logical that the dollar signed used in the shared drive should work, when the shared folder doesn’t.
