Webmail powered by Microsoft Outlook

SLAC IT recommends using SLAC Webmail, powered by Microsoft Outlook. This is the only fully supported email application at SLAC. This requires no setup, is robust in features, is easy to access, and avoids issues with basic and modern authentication. You will not have to worry about patching or installing the latest updates as this is centrally managed. You will always have the most up to date version.

NOTE: If you are new user and have not reset your password, please do so at the SLAC Active Directory (Windows) Password Reset website or SLAC ADFS Password Reset website.

For SLAC Employees/Interns, and Stanford users with fully-sponsored SUNet IDs, who still want to use the desktop Outlook application - you will need to download the entire Office365 suite.

Downloading the Microsoft Office365 Suite

Windows and macOS

• Sign in to webmail using the instructions above, then visit aka.ms/office-install
• Click the "Install Office" button:

macOS (Outlook application only)

• Download from Microsoft Outlook from the Apple App Store
  

Thunderbird

Thunderbird can be configured for use with your SLAC Office365 email using the OWL plugin. Please see KB0011877 for details on installation.

Apple Mail App (iOS [iPhone, iPad] and MacOS [MacBook, iMac])

The Mail app on Apple devices can be configured for use with your SLAC Office365 email. Please see KB0011897 for details on installation.

SMTP, IMAP, POP Protocols

On July 3, 2019, the SLAC Cybersecurity team issued a Memorandum indicating that mail access would be restricted to a few mail applications. In summary, SLAC currently restricts access of SMTP, IMAP, and POP email protocols with SLAC email accounts so that traffic can only originate from the SLAC network. Consequently, those who use these protocols from outside of SLAC are now required to log into VPN first. More information on Thunderbird-specific configurations and general restrictions can be found here.

Basic and Modern Authentication Protocols

Beginning October 1, 2022, Microsoft will enforce modern authentication when you access your SLAC Office365 email. Email clients that use the legacy authentication beyond October will stop working. If you set up your SLAC Office365 email using one of the above methods, your email access uses modern authentication. For more details, please see KB0011889.
