Latest Message<\/th>\nTitle: Users may be unable to access some Exchange Online archive mailboxes<\/p>\n

User impact: Users may be unable to access some Exchange Online archive mailboxes.<\/p>\n

More info: This issue occurs when routine mailbox database maintenance for archive mailboxes relocates the archive to a different portion of Active Directory infrastructure from the primary mailbox. Impact may persist both during the maintenance move and after the move. The problem impacts archive mailbox access through any Exchange Online connection method.<\/p>\n

Current status: As we progress with our root cause analysis and confirm the source for this event, we completed our fix validations and deployed our solutions. We’re projecting that deployments will be complete and impact to be remediated by the third week of October, and we expect a more detailed timeline to be available by our next scheduled communication update.<\/p>\n

Scope of impact: Any user attempting to access their Exchange Online archive mailbox may encounter this issue if their primary and archive mailboxes aren’t located on the same portion of Active Directory infrastructure.<\/p>\n
