For more information, see Overview of auto-expanding archiving. Additional storage space is added incrementally until the archive storage capacity reaches 1.5 TB. When auto-expanding archiving is turned on, additional storage is automatically added when the 100 GB storage capacity is reached. Storage limits Featureġ Each user initially receives 100 GB of storage in the archive mailbox. Microsoft reserves the right to deny additional archive storage space in instances where a user's archive mailbox is used to store archive data for other users or in other cases of inappropriate use. A user's archive mailbox is intended for just that user. Using journaling, transport rules, or auto-forwarding rules to copy messages to an Exchange Online mailbox for the purposes of archiving is not permitted. Administrators can reduce maximum mailbox sizes per user or globally. The amount of mailbox storage available is determined by the mailbox type and the user's subscription license.
