Presence messages are managed for one or more members of a pre-defined group of e-mail users. An unavailability time period, during which a pre-defined group of e-mail users will be unavailable in the future, is established. A notice, which notifies the pre-defined group of e-mail users that an unavailability control instruction will be sent in the future to participating members of the group of e-mail users, is transmitted to the group of e-mail users. An acceptance signal, identifying the participating members, is received, indicating which members of the group of e-mail users agree to permit the unavailability control instruction to be received and implemented on their participating computers in the future. The unavailability control instruction is then transmitted to the participating computers at an initiation of the unavailability time period, in order to auto-generate an appropriate presence message for the participating members. |
