If you exceed the number of users included in your license, your Confluence instance will become read-only, that means no users will be able to create or edit content until you reduce the number of users.
You can reduce your user count by removing or deactivating users who do not require access to Confluence. See Deleting or Deactivating Users.
If you have connected Confluence to an LDAP directory, you may want configure Confluence to only synchronise a subset of users from LDAP rather than all users. See How to change the number of users synchronized from LDAP to Confluence in the Knowledge Base. This can be a complicated process and we recommend that you only use this method if necessary.
If you decide to downgrade your Confluence license to pay for fewer users you need to ensure that the number of users currently signed up (as shown on the License Details page) is lower that the number allowed by your new license before your apply the new license.
If you have more users than your new license allows you will need to reduce your user count before applying the new license.
