Microsoft Exchange was recently configured so that a banner message appears on all emails originating outside of U-M when they include an attachment or web link. This change was in response to the significant number of increasingly sophisticated email scams across Michigan Medicine.
Based on feedback received from the Michigan Medicine community, the following changes will be made on Thursday, November 8:
- Reduce the current banner message from 23 words to four words:
External Email -- Use Caution
- Add more space between the banner message and the beginning of the email text.
“We hope this banner message helps employees better identify valid emails vs. fraudulent emails that appear to be sent from an internal source,” said Jack Kufahl, Michigan Medicine chief information security officer. “We will continue to review the email banner, and make any necessary adjustments, on a quarterly basis.”
