As projects come and go, so too will your group members. Undoubtedly, you'll need to add and remove members over the life of the group; you might even need to add or remove group owners.

Any member of a group​​​​​​​ can invite others to the group, but only the group owner can remove them. The group owner is usually the person who created the group but others can be assigned this role as well. It's recommended that groups should have at least two owners, in case one of them is unavailable.

Select the tab that corresponds with your version of outlook for instructions on adding and removing members, including guest members.
