How to Manage Incoming Mail Effectively
1. SPAM EMAILS
What To Do:
If you receive mail from a sender you recognize and you cannot unsubscribe, you can BLOCK them and move the mail to your JUNK folder
You are protected against spam under Canada’s anti-spam legislation (CASL). Learn about the legislation as well as how to protect yourself from spam and how to report it when necessary.
If you have not given permission to receive unwanted mail from a sender, you can also report them to the Canadian Radio-television and Telecommunications Commission.
2. PHISHING EMAILS
Phishing is a type of online attack in which an attacker — using both technological and psychological tactics — sends one or more individuals an unsolicited email, social media post, or instant message designed to trick the recipient into revealing sensitive information or downloading malware.
Phishing attacks can be generic or customized and can target both individuals and entire organizations. Attacks that target a specific individual or organization are commonly referred to as spear phishing attacks.
The main goal of a phishing attack is to get the individual to do something that compromises the security of their system and/or potentially their organization. To stop attackers from achieving this, when you receive a suspicious email:
- Be Careful of opening email attachments from unsolicited senders. Email attachments can contain malware.
- Be Careful of links. Fake websites or pages can install malware. Hover our mouse over links to see the destination URL.
- Be Careful of entering usernames, passwords, or other sensitive information on websites. Hackers can create fake yet identical login pages. If possible, navigate to the website manually.
- DO NOT reply to phishing emails with confidential information such as login credentials. No McMaster email address will ask for your credentials.
Phishing messages can range from very basic to highly sophisticated. Common “red flags” or indicators include:
- The suspicious sender or reply-to address: always treat messages from unknown or unfamiliar senders or accounts with extra caution.
- Unexpected message: messages from recognized senders that are unrelated to normal communications or job responsibilities can signal an account has been compromised or is fake.
- Suspicious attachment: messages with unexpected or unusual attachments can contain malware.
- Suspicious link: messages that encourage recipients to click and follow embedded hyperlinks may point to websites unrelated to the message and under the control of the attackers.
- Poor spelling: spelling and grammar errors may indicate a phishing attack since legitimate organizations typically avoid these mistakes in their communications.
What To Do:
If you think you have been phished or hacked, don’t be embarrassed. The best thing to do is report to the UTS Service Desk.
All suspicious messages must be reported to is-spam@mcmaster.ca and the message should be deleted from your inbox and your deleted folder. Reporting phishing attempts and suspicious messages helps keep the McMaster community safer.
Then, delete or move the emails to JUNK.

3. HARASSMENT EMAILS
McMaster Community Members who have experienced unwelcome comments or conduct by another person are encouraged, although not obliged, to make it known to the other person that their behaviour is unwelcome.
What To Do:
In situations where it is believed that addressing the other person could lead to an escalation of the comment or conduct or safety risks, this approach is not recommended. If the problem is not resolved, or if you feel you cannot respond directly to the other person, notify an appropriate Supervisor, or contact HR (staff) or Campus Police (staff and students).
Use a RULE to move the emails to Junk or keep them in a separate folder for investigation. Rules can also help filter out specific words/names that repeatedly come from different or hidden email addresses.
4. CREATING RULES
Rules allow you to move, flag, and respond to email messages automatically. You can also use rules to play sounds, move messages to folders, or display new item alerts.
The easiest and most common rule to create is one that allows you to move an item from a certain sender or with certain words in the subject line to another folder. You can create this rule directly from a message you’ve already received.
5. BLOCK SENDERS OR MARK EMAIL AS JUNK (AND OTHER OPTIONS)
6. HOW TO MANAGE JUNK MAIL
No one likes spam or junk email. The Outlook Junk Email Filter doesn’t stop the delivery of junk email messages, but does the next best thing—it moves suspected spam to the Junk Email folder.

Moving forward, McMaster University will look to take advantage of these advanced features.
A Focused Inbox separates your inbox into two tabs – Focused and Other. Your most important email messages are on the Focused tab while the rest remain easily accessible – but out of the way in the Other tab.

There are a number of ways that McMaster Mail (powered by Microsoft 365) works with Microsoft Teams for an enhanced calendaring experience. Check out the videos below to see the new meeting and scheduling functionality available to users after they migrate.
G-Suite FAQs
You will continue to work in Gmail and the GSuite until after exams and the semester ends. At that time, the only thing that changes is Gmail to Microsoft 365. You will continue to have access to your GSuite until well into 2022.
You will retain access to GSuite until well into 2022 to manually back up and save any data you wish to keep. After the specified decommissioning date, your McMaster GSuite account will be fully terminated and any remaining data will be deleted. You will receive notifications before this happens.
- Word > Google Docs (word processing)
- Excel > Google Sheets (spreadsheets)
- PowerPoint > Google Slides (presentations)
- Outlook Online > Gmail (email)
- One Note Online > Google Keep (notes)
- SharePoint > Google Sites (website building)
- Microsoft Teams > Google Meet (conference calling / chat messaging)
These are broad equivalents, in that their feature set is not exactly going to match the corresponding app.
All clubs created prior to 2022 have a McMaster G-suite account and are required to migrate any files you wish to keep to the clubs Microsoft Team prior to the decommission date.
Storage FAQs
Students will have 1 TB of storage on OneDrive.
The email migration itself will have no effect on your Google Drive data. However, you will have until spring 2022 to back up and save any Drive data. After spring 2022, all remaining data on your Google Drive will be deleted.
See instructions on How to Transfer Data from Google Drive to OneDrive for Active Students and How to Download your Google Drive Data for Active and Graduated Students.
Active students have 1TB of cloud storage in OneDrive. Moving your data would protect your most precious files and documents with OneDrive. You get 1 TB of cloud storage with a Microsoft 365 subscription and can backup and share your documents with friends and family across all your devices.?
You can move 1TB of data over to OneDrive or store your files on another cloud service or a specific device (hard drive, USB etc.)
Note: Repeat the process for each drive within your google drive, shared included
Note: MAC USERS: Your zip folder will automatically be unzipped and placed in the trash can leaving the unzipped folder in your Downloads.
