The University of Iowa email system recently moved to Microsoft’s Office 365 platform, which provides many modern features like 50 GB email quotas and improved mobile access. We continually review technology services for efficiency and functionality and an opportunity exists to consolidate anti-spam protection into the same Office 365 platform. We believe this will reduce costs for the University of Iowa and improve the technology.

Two changes will occur on Wednesday, June 21, 2017 at 9:00am:

  • The uiowa.edu domain mail exchanger record (MX record) will begin routing all University of Iowa email directly to Microsoft Office 365 which will then distribute to the appropriate system (e.g., Office 365, Healthcare, Gmail, etc.). 

  • Microsoft’s Office 365 anti-spam services (Exchange Online Protection (EOP)) will become the primary protection for all University of Iowa email accounts.  We will no longer be using Sophos.

Redirecting email flow and anti-spam protection to Office 365 allows the UI to decommission several servers and third-party license agreements. These changes, along with the staff effort required to maintain the systems, will save the UI money. The Office 365 systems can also handle greater email traffic load and provide a more robust service to campus.

Potential spam messages will automatically be moved into the Junk Email folder.

Consolidating anti-spam protection into Office 365 provides a greater level of integration with the email system. For instance, moving an email message into the Junk Email folder can automatically signal to Microsoft that the message is unwanted. If a large quantity of UI individuals identify a message as unwanted, Office 365 will begin identifying that message as spam.

Since we will no longer be using Sophos for anti-spam protection, potential spam messages will no longer be tagged with Spam?# so any rules to filter spam?# you had setup previously will need to be updated or removed.

Each anti-spam protection tool has the same goal of blocking undesirable messages while allowing all other email communication. However, each platform accomplishes that with slightly different rules, algorithms and processes. Office 365 will continue to block spam, but the type or quantity of messages in the Junk Email folder may differ.

You may see more messages in your Junk Email folder with this change.  We recommend checking it more often.  If you find messages in the Junk Email folder that you don't think should be, you mark them as Not Junk and they will be moved back to the Inbox.  This also automatically notifies Microsoft that the message isn't junk.   For information on how to mark messages as Junk or Not Junk, see How Do I Manage Junk Email and Spam?

You may also notice that some messages may get marked with the warning "This sender failed our fraud detection checks and may not be who they appear to be."   See Messages Flagged as "This sender failed our fraud detection checks and may not be who they appear to be" for more information.

  • Sending and receiving email will continue to function normally throughout this change.
  • Individual email users may notice a difference in the type or quantity of spam messages. If additional spam begins delivering to your Inbox, please verify that you have Automatic Junk email filtering enabled using the following instructions.
  • In the unlikely event of systemic issues, it will be possible to revert to the older systems temporarily.

If important messages routinely deliver to the Junk Email folder please contact the ITS Help Desk so we can adjust the system appropriately.

  • Verify that you have Automatic Junk email filtering enabled on your Office 365 account using the following instructions 

  • Rather than deleting spam messages, move the message into the Junk Email folder. This process can automatically signal to Microsoft that the message is unwanted.

  • Continue to report phishing scams using the following instructions.
