Service overview

McGill provides email services through Exchange Online, a cloud-based service that is part of McGill's Office 365 package from Microsoft. Students, faculty and staff members, as well as affiliates, have slightly different account settings and access privileges to their email. See table below.

Important: McGill Outlook email storage capacity reduction starting May 31st 2024


On May 31st, 2024, McGill’s Outlook email storage for all students will be reduced to 20GB to comply with Microsoft’s new Storage quota for its educational sector clients. The Outlook email storage provided to staff or faculty members will not be affected.

If you are a McGill student, please verify your current storage using the instructions in this article: How to check file storage usage in outlook.

If your current storage exceeds 20GB, start by emptying your mailbox’s deleted items. As a secondary step, go through your inbox and all its online storage folders and download any "big" attachments such as videos, PowerPoint presentations or images by saving them to another location using the Save as... option in the attachment drop-down menu and then by Removing them.

Please note: these options are only available on Outlook for PC, not on the online or Mac versions. If you only use these platforms, download the attachments then save/delete the email. (Don't forget to empty the deleted items folder after.)

If you plan on storing those files on OneDrive, be aware that OneDrive's storage will also be adjusted to 20GB starting May 31st. For more information: consult the IT Services announcement on the subject.


Important: Change to the recipient limits for your Non-2FA enabled McGill email 

In an effort to limit the impacts of unsolicited and fraudulent emails being sent in large numbers to the McGill community, McGill’s IT Infrastructure & Information Security has decided to limit the number of emails that can be sent from non-2FA (two-factor authentication) enabled email accounts.

This limit will be imposed on all such accounts as of October 3rd, 2023. From that date on, accounts that are NOT two-Factor Authentication (2FA) enabled (at this moment, mostly Alumni and Retirees’ accounts) will be restricted to sending messages to a maximum of 100 recipients per 24 hours. This limit is imposed on the number of recipients, regardless of the number of emails sent.

Important: McGill Active Directory managed distribution lists are not affected by this change. Such distribution lists are treated as 1 recipient.

Students who graduate, and employees who retire from McGill can keep their McGill email address and mailbox.

Students who leave McGill without graduating and employees who leave without retiring will lose their McGill email when their status changes. You will be notified approximately one month before your email account is deactivated.

How to request & access the service


Newly admitted students: You are given a McGill Email Address and mailbox automatically when you confirm your acceptance to McGill. Notification about your McGill Email Address is sent to the non-McGill email address you entered on your application form.

Re-admitted students: Your mailbox will be re-instated once you register for classes.

School of Continuing Studies students: Your mailbox will be created when you register for classes.

Faculty & staff

Upon employment at McGill, an email box is created automatically. Once your email box has been created, your McGill email address will be listed on Minerva via Personal Menu > Email Addresses. If there is no McGill email address listed, contact the IT Service Desk.

Best practices & policies

Your McGill Email Address is one of the official means of communication between the University and you; please ensure you check your McGill email regularly. Students, please see the University's policy on E-Mail Communication with Students.


TIP: Using email for mass communications

In Exchange Online (Office 365), for each message, you can send a single message to a maximum of 500 recipients, and you can send to a maximum of 10,000 recipients within a 24-hour period.

Each recipient listed in the To, Cc or Bcc fields is counted as a separate item, whereas an email sent to a group or LISTSERV is only counted as one item. If you need to send emails to large audiences, you may want to manage distribution lists via LISTSERV or email-enabled Active Directory groups in Exchange. See Email distribution lists.
