Microsoft recently pushed a security update to Office 365 that expands the list of file types that are blocked as attachments. Information Technology Services has learned that this update may result in a small percentage of employees being unable to open attachments containing these file types.
If you experience a problem with attachments from known and trusted senders, please contact the ITS Service Desk at 304.293.4444. We will create a ticket, then have a support specialist contact you for additional details to find a solution that meets your needs.
