If the user has started public documents in the "Documents" module, it is important to check that the user has transferred administrative access in these documents before deactivating.

A user can be automatically deactivated by the system in the following cases:
If the user has not used the invitation. The invitation is active for 7 days after it was sent.
If you have a subscription with a limited number of users and you invite users beyond the number of paid licenses. In this case you can buy the required number of licenses or deactivate inactive users, if any.
