MX Record Migration Project

We have completed a 6-stage process to having our MX records directed to Microsoft which permitted the enabling of Exchange Online Protection (EOP) and other e-mail security features. Multiple steps were taken to ensure each functioned correctly before proceeding to the next. The following info outlines each step and when it occurred.

  • Stage 1: Updated routing of mail being sent to @utoronto.ca and @mail.utoronto.ca addresses
    All messages being sent to @utoronto.ca and @mail.utoronto.ca accounts have been routed directly through UTmail+ (O365) rather than through our on-prem infrastructure.
    This change occurred on Tuesday, July 16th, 2019.
  • Stage 2Updated routing of mail from UTMail+ to UTORmail
    All messages being sent from UTmail+ accounts to UTORmail accounts have been routed directly to UTORmail accounts.
    This change occurred on July 22nd, 2019.
  • Stage 3: Updated routing of mail from UTORexchange to UTORmail and external recipients
    All messages being sent from UTORexchange accounts to UTORmail accounts and external recipients have been routed through UTmail+ (O365).
    All messages from UTORexchange destined for external recipients are now scanned by Exchange Online Protection (EOP). Note that EOP may block senders who are sending bulk or suspected spam to external recipients.
    This change occurred on July 23rd, 2019.
  • Stage 4: Updated routing of mail from UTORmail and external recipients to UTORexchange
    All messages being sent from UTORmail accounts and external recipients accounts to UTORexchange have been routed through UTmail+ (O365).
    This change occurred on July 24th, 2019.
  • Stage 5: Updated recipient information in UTmail+
    Updates to recipient information allows for the direct routing of messages being sent from UTmail+ accounts to UTORmail accounts.
    This change occurred on Tuesday, July 25th, 2019.
  • Stage 6: Updated routing of mail from external senders to UTmail+
    All messages being sent from external accounts to UTmail+ accounts have been routed through UTmail+ (O365).
    This change occurred on July 31st, 2019.
    This final change included the activation of a number of new features through Exchange Online Protection (EOP) which is the primary filter for suspected spam (SCL of 5 and above), phishing, virus and unwanted bulk (BCL of 7 and above) emails.

    1. Advanced spoof filtering (suspected spoof emails are delivered to the junk folder)
    2. Bulk filtering (unwanted bulk emails are delivered to the junk folder)
    3. Phishing or potential viruses (suspected phishing emails or emails containing viruses are quarantined)
    4. Personalized allow and block lists (individuals now have the ability to personalize their own “white list” email addresses and block list email addresses or domains through Outlook or OWA
    5. Message reporting (allows individuals to report false positives or false negatives for messages that have been incorrectly marked as SPAM or non-SPAM)
    6. Blocking executable attachments (attachments are quarantined)
    7. Zero-hour auto purge (ZAP) (detects phishing messages or messages containing malware that have already been delivered to the Inbox, and then renders the malicious content harmless)
    8. TLS 1.2 encryption for external mail flow
    9. The ability to modify custom spam filter levels is longer be available.

    For details on how to use Message Reporting or personalizing an Allow and Block list, see Office 365 Tip #26 – Ensuring that email messages incorrectly marked as spam are received in the future as valid mail.

    If you run into any NDRs, please report it to the Information Commons Help Desk (416-978-HELP) or help.desk@utoronto.ca.
