Behind the Scenes: Storage of Attachments in Exchange Online

1. Stored Within Your Mailbox on Microsoft’s Servers

Mailbox Database: In Exchange Online, attachments are stored as part of your mailbox, which resides on Microsoft’s secure servers in the cloud.

Emails and Attachments Together: Each email, along with its attachments, is stored as an item within your mailbox database.
