What’s the Real Size of Exchange Online Mailboxes?


The Office 365 Substrate uses Exchange Online mailboxes to store a lot of data that users never see.

How Exchange Online Processes Journal Reports for Protected Email

Office 365 tenants often want to journal email from Exchange Online mailboxes.
