MFA Enforcement Today + Teams Phone Updates Required

MFA enforcement for Microsoft 365 Admin Center is live today. Teams Direct Routing and Phone device updates are due this month. Plus Copilot Memory is coming in March.

🚨 MFA Enforcement for M365 Admin Center — EFFECTIVE TODAY

Starting February 9, 2026, Microsoft is fully enforcing MFA for all Microsoft 365 admin center sign-ins. This is not a drill — admins without MFA configured cannot access the admin center.

There are no more grace periods or exceptions. If any of your admin accounts aren't enrolled, they're locked out as of today. Verify immediately.

🚨 Teams Direct Routing Configuration Changes

Deadline: End of February 2026

Changes to SIP configuration requirements affect all organizations using Teams Direct Routing for voice. This is a compliance and functionality issue — missing the deadline could impact your telephony.

What to do:

• Validate Session Border Controller (SBC) configurations
• Coordinate with your telephony vendors immediately
• Test in a pilot environment before production changes

🚨 Teams Phone Recording Consent Update

Status: Requires device updates

Teams Phone Devices require an app update to enable Explicit Recording Consent. Without updating, devices may not properly enforce consent requirements — potentially a compliance risk.

🔥 The Bottom Line

Today is MFA day. If you haven't verified all your admin accounts have MFA enrolled, that's job one. Everything else can wait until that's confirmed.

The Teams Direct Routing changes and Phone device updates are your priority for the rest of February. Both have compliance implications — don't let them slip.

Copilot Memory in March is worth watching — better Graph integration means more useful AI assistance, but also worth reviewing your data governance before rollout.

Stay sharp. Stay secure.
