Flank Speed (DoD Microsoft 365) — Quick Help for CRL Users
What is Flank Speed?
Flank Speed is the DoD/Navy Microsoft 365 environment used for email, Teams meetings, and collaboration. If you work with Navy/DoD partners, you may need to join their Teams meetings using your DoD account (separate from your CRL Teams sign-in).
Join a DoD Teams meeting (recommended)
-
Open Microsoft Edge and start an InPrivate window (or use another browser’s private mode).
-
When prompted, sign in with your DoD account.
-
Open the meeting link and select “Continue on this browser” to join in Teams on the web.
Why use InPrivate / Private browsing?
Private browsing keeps your DoD sign-in separate from your CRL sign-in and helps prevent account conflicts (for example, being signed into the wrong tenant).
Access DoD M365 apps (web)
If you have DoD access and a CAC/PIV, you may be able to reach DoD Microsoft 365 services here:
