The last step in a security upgrade for the UOmail system has been rescheduled for July 6.

The change may temporarily interrupt email access for some University of Oregon community members.

Information Services will be making a systemwide change to the cloud-hosted UOmail service that will require email programs to use a newer, more secure way of checking UOmail login credentials. The university is making this switch to “modern authentication” ahead of a worldwide Microsoft deadline in October for everyone who uses Exchange Online, the platform behind UOmail.

The systemwide change was originally made June 27. However, unexpected problems prompted staff to undo it within a few hours.

"Our staff members have identified and resolved the bugs that interfered with our first attempt," said Patrick Chinn, associate chief information officer for customer experience.

After the July 6 change, some students and employees may receive an automated email message with the subject line “Your email access has been blocked.”

More information about how to respond to that message is available in Around the O.

Anyone seeking help with email can contact the IT staff members who support their unit or the Technology Service Desk or submit a ticket through the email and calendar help page of the UO Service Portal.
