Question:
Can multiple external users be logged into under the guest account login?
 
Solution:
It is not possible for multiple users to access a guest account simultaneously. Since a guest account utilizes a named license, as per our license agreement, once a user logs out, the session associated with the application remains open for another 2 minutes.
After the 2 minutes are reached, the session is closed/removed and the named license can be used.
