Currently, SharedMailBoxUser and SharedOneDriveUser both are set to "-Single" which only allows 1 user to be selected to Share to. Loop will need to be created for sharing in 2 places - will need to adjust where in script things run, planned for future update
"Future Update" means if a need arises, as this is a severe edge case and I have not seen nor heard of it. Please update this issue if you do run into it.
