If a group is using [User caps for groups](https://docs.gitlab.com/ee/user/group/manage.html#user-cap-for-groups) and has hit the user cap limit, then new users cannot be added to the group. **This includes inviting Guest users on an Ultimate subscription only.** In this issue, we will change that behavior to allow, on Ultimate, inviting a new Guest user to the group even if the group is at or over the user cap limit. This is similar behavior to the change for [Self-Managed User Caps](https://docs.gitlab.com/ee/administration/settings/sign_up_restrictions.html#user-cap) that was completed in https://gitlab.com/gitlab-org/gitlab/-/issues/361563. See note here: https://gitlab.com/gitlab-org/gitlab/-/issues/361563#note_1763416727 **Documentation Update Required**: [The documentation here](https://docs.gitlab.com/ee/user/group/manage.html#known-issues) needs to be updated when this is behavior is changed. The following text will no longer be accurate: > On GitLab.com, on the Ultimate tier, there is a known issue where you cannot add new guest users to a group when the amount of billable users exceeds the user cap. For example, suppose you have a user cap of 5, with 3 developers and 2 guests. After you add 2 more developers, you cannot add any more users, even if they are guest users that don’t consume a billable seat.
