Unable to Change Access Level from Guest to External User

Original Question or Issue:

A specific user account cannot be set back to "External Users" due to an unusual domain prefix format in their email address.
🔹 As a workaround, we are trying to assign a "Guest" license temporarily for a user based in China.
⚠️ FileCloud will not allow the role change due to this formatting issue.

Environment:

• Product - Filecloud Server
• Version - 23.251
• Platform - Any

Steps to Reproduce:

Error or Log Message:

Invalid Email for External Accounts

Defect or Enhancement Number:

Cause:

Current calculation for external domains is wrong in cases where there are few licensed users.

Resolution or Workaround:

This will be addressed in our future release with ticket ID:  FCL-3741

• Disable the user first

• Set user with External Access
