Microsoft Purview

Updated July 17, 2026: We have updated the timeline. Thank you for your patience. [Introduction] To help organizations better protect sensitive files in transit, we're introducing a public preview for extending Microsoft Purview Data Loss Prevention (DLP) policies to the network through integration with Entra Global Secure Access Internet Access. Through this integration, organizations can intercept and inspect file traffic at the network layer and enforce actions based on DLP policy conditions. It helps prevent sensitive files from being shared with untrusted cloud applications through browsers, apps, APIs, add-ins, and more—including generative AI platforms, cloud storage, and content-sharing services—while managing alerts and incidents through Purview and Microsoft Defender.This message is associated with Roadmap ID 522096.

Exchange Online

Updated July 15, 2026: We have updated the timeline. Thank you for your patience. [Introduction] Microsoft is retiring the -Credential parameter used when connecting to Exchange Online PowerShell. Starting with module versions released in December 2026 and later, the -Credential parameter will be removed from both Connect-ExchangeOnline and Connect-IppsSession cmdlets. Organizations using this parameter in automation scripts must migrate to a supported authentication method before that date. This change improves security by moving away from legacy authentication methods that do not support modern protections such as multifactor authentication (MFA). [When this will happen:] The -Credential parameter will be removed from Connect-ExchangeOnline and Connect-IppsSession cmdlets in Exchange Online PowerShell module versions released beginning end of year 2026 (previously July).
