MacMail Email Information for Retirees

The Microsoft Outlook Web Application (OWA) and Microsoft Outlook are the email applications supported by McMaster for MacMail. Other email client software such as Thunderbird and Apple Mail should work, but they may not handle all the features of MacMail and are not officially supported by the University.  

Note: Although Outlook Web App (OWA) is the recommended way to access MacMail, importing Contact information from other email applications is not supported by OWA.  You will have access to the McMaster ‘Global Address Book’ with OWA, which contains all McMaster people who use a email address.   You will have to add non-McMaster Contact information to OWA manually.   For this reason, users with extensive ‘address books’ may wish  to use a different email application (e.g. Microsoft Outlook, Thunderbird, Apple Mail) to access their MacMail accounts.

Ways to Access MacMail

a)  Outlook Web App (OWA)(for your PC, Mac or mobile device)

                  Recommended - works from any location via a web browser

Easily access MacMail from anywhere using Microsoft Outlook Web App (OWA) via a web browser such as Internet Explorer, Firefox, Safari or Chrome.

  1. Using a web browser such as Internet Explorer, Firefox, Safari, or Chrome

Notes about using Chrome to access OWA:  

  • To use the Chrome browser, you will need to install the free Silverlight Plugin(see for download and instructions)
  • With recent versions of Chrome, some features of OWA such as the Global Address Book will not work even with Silverlight installed. Chrome users may wish to use another browser for some or all of their Webmail access

b)  Microsoft Outlook Email Application (for your PC or Mac)

Outlook 2010 and Outlook 2013 are the versions supported by McMaster.   Please note that Outlook 2007 will only support one email account when configured for Microsoft Exchange.

NOTE:  Screen locations and choices may differ from samples given, depending on manufacturer and operating system version.


d)  Thunderbird Email Application (for your PC or Mac)

Choose POP or IMAP

POP downloads emails from the MacMail inbox to your Thunderbird Inbox on your local computer and deletes them from the MacMail server after 14 days.

IMAP accesses your emails on the MacMail server without downloading them to your local computer.  Emails remain on the MacMail server until you delete them.

Notes on using Thunder bird:

  • If you use Thunderbird for MacMail be aware there is no access to the Global Address List or Calendar. If you require access to these features, you will have to use OWA (the Outlook Web App)or the Microsoft Outlook Email Application.
  • Thunderbird users will need to use VPN (Virtual Private Network) to access MacMail from outside the McMaster network.Without it, you will be able to receive mail, but will not be able to send mail.Installation and configuration information for VPN can be found at
  • If you are using IMAP, you may find that not all of your mail folders are visible. To fix this, in the Thunderbird Menu select Tools|Account Settings |Server Settings |Advanced.In the IMAP area, uncheck ‘Show only subscribed folders’
  • If you want Thunderbird to put your sent mail in 'Sent Items', which is the folder your mobile device and OWAuse, after configuring Thunderbird:
  • On the Thunderbird Menu Bar, select File | Subscribe.     Scroll down, select the Sent Items folder, then click Subscribe, then click OK.
  • In the Thunderbird Menu select Tools | Account Settings | Copies & Folders.    In the 'When sending messages, automatically’ area, select Other.  In the drop-down list, select your user name, select the 'Sent Items' folder, then click OK. 


e)  OS X Apple Mail Application (for your Mac)

Email Forwarding

  • If you forward your emails from UnivMail to a non-McMaster account, you have options.
    • Option 1: Set a rule in MacMail to forward your email to your non-McMaster account. See Webmail: How to setup a rule
    • Option 2: Send an email to with your MAC ID and non-McMaster email address, with a request that your non-McMaster email address be linked to your McMaster email address. With this option, you will not have a MacMail account that you can use directly. Instead, emails sent to your McMaster email address will be redirected to the non-McMaster email you provide.


  • If you think you have forgotten your MAC ID, use the ‘Verify my MAC ID’ tool.  Alternatively, contact the UTS Service Desk.
