A bug in Outlook desktop’s implementation of the MAPI over HTTP protocol allows users whose mailboxes are on hold to remove attachments from messages. The removal is not captured by the copy-on-write feature of Exchange Online Native Data Protection, which potentially compromises the ability of Data Governance managers or eDiscovery investigators to recover information needed for compliance purposes.

Microsoft Plans to Disable SMTP Authenticated Submissions in Exchange Online

Exploring the Office 365 Substrate

The Office 365 Substrate is a poorly understood part of Microsoft’s Cloud Office system. The substrate is a critical part of enabling services that run across different applications like Exchange Online, SharePoint Online, Teams, and so on.

Tracking Anonymous Access to SharePoint and OneDrive Documents

Cloudy attachments are an excellent way of sharing documents through email without attaching files. Behind the scenes, an anonymous link to the document is sent to recipients, who can then use the link to open, edit, or download the document (depending on the assigned permission).
