Office 365 Email

...because email is a must.

Let's face it, the world is dependent on email for communication.  William & Mary is no exception.  We have relied on Microsoft as a email service since 2010.  In 2017, we transitioned our onsite Exchange servers to Microsoft Office 365, which is a Cloud service.  Here's what you need to get started with Microsoft Office 365 Email.

Client Installation

Outlook desktop clients are available for both PC's and Macs. 

  • PCs on the W&M leasing program - An Outlook client will be installed for you before you receive the computer.  
  • Macs or PCs outside of the leasing program - Contact the Technology Support Center for Outlook installation.
Online Access to Outlook

You can access your W&M email online several ways.  Here are some options:

Mobile Settings

Want to set-up email on your phone?  Here's the settings you need:

  • Description of Mailbox: Exchange 
  • Server Name: outlook.office365.com
  • Username: Enter your W&M Username
  • Password: Enter your password for your W&M Username

Many of the Office 365 services have apps available for smartphones - including email!  Find them in your iPhone App Store or Google Play store. Microsoft recommends all Apple devices to use Outlook for iOS.  Sign in with your W&M email address and you will be directed to the W&M authentication site.

Apple Devices  -  If a devices is running iOS 10.x and using ‘Outlook for iOS’ Microsoft is going to stop mail and calendar from syncing.  It is recommended for all apple devices running iOS 10.x be upgraded.

IMAP Settings

IMAP clients will need to be reconfigured with the following settings:

  • Server name:  outlook.office365.com
  • Port: 993
  • Encryption method: TLS


  • Server name: smtp.office365.com
  • Port number: 587
  • Encryption method: Start TLS

MacMail version 10.12 (Sierra) works with Office 365.  Instructions for Setting Up MacMail 10.12

Note: In testing we have found that earlier versions of MacMail have problems loading emails and viewing shared Calendars.  If you do not want to upgrade to 10.12, we recommend using the Outlook client or Outlook webmail (outlook.wm.edu) instead.
