I just received an email from Box saying that the number of Box licenses is insufficient.
So, when I logged in with the admin account and checked, 12 licenses were being used.
Since the purchase was for 5 licenses, this means it is exceeding by 7 licenses.
It seems that the account I created for free was automatically changed to a company-managed user.
Once those accounts were deleted, the number of licenses returned to 5, so the problem was resolved.
However, it is unclear why the free account was automatically set as managed.
The admin account has domain management capabilities, but the automatic registration setting is disabled.
There were also accounts within the same group that were not managed.
The fact that I suddenly received a message from the box suggests that it was something changed recently, but all the accounts I deleted were created quite some time ago.
Since the cause is unknown, I wanted to consult with you as there is a possibility that the same phenomenon may occur in the future.
I would be grateful for your response.
