External Email Warning

OSU Enterprise IT has switched to the new Microsoft “First Contact Safety Tip” Banner for external emails, doing away with the former email banner below:

The new banner will be more intelligent, helping to identify spam by showing the full sending email address on most clients if you have not received correspondence from the address previously. It will also not show for external senders with whom you regularly correspond.

The new banner can be seen below:

If you believe this message is Spam or a Phishing Attempt, please forward the email to helpdesk@okstate.edu for further assistance.

  The difference between the current student and alumni license is current students have access to Online Microsoft Applications (Word, Excel, PowerPoint, OneDrive, etc.) and the Cowboy Mail email inbox while alumni only have access to the Cowboy Mail email inbox.
