Technologies are described to increase a data limit for a user of a communication application by introducing additional archive mailboxes as the original archive fills up or subsequently added archive mailboxes fill up. Thus, a user's data limit may be effectively removed through the use of N additional archive mailboxes. The additional mailboxes may be integrated into the architecture of the communication application such that their use is transparent to the user and/or an administrator of the communication application or associated service. In other examples, additional mailboxes may be used to add to the capacity of the primary mailbox (cached) as well.
