Monitoring
Microsoft has notified us that the restriction on sending email to external recipients has been lifted; however, given the size of our email system, it could take until 2pm for all accounts to return to normal.

Barring any unexpected issues, this is the last update we will send regarding this outage.
If you have any questions, please contact the IT Service Desk.

Identified
Outgoing mail to non-OHIO recipients continues to be rejected. Microsoft has confirmed that this is related to spam being sent from a number of OHIO student accounts. We are in the process of disabling those accounts. Once all of the affected accounts have been disabled and the volume of spam drops to acceptable levels, Microsoft will restore the ability to send to external recipients.
Cause of the Outage
A password database from the Chegg educational technology company was recently published online. Because a number of OHIO students re-used their OHIO passwords when they created an account with Chegg, those students' accounts were taken over by hackers and repurposed to send spam.
This does not represent a breach of any OHIO online systems, but it does have two inconvenient consequences:
1. The affected users' accounts have been locked, and they will need to reset their password before they will be
able login to any OHIO online services.
2. Due to the volume of spam coming from the affected accounts, Microsoft has temporarily restricted Ohio
University from sending mail to non-OHIO recipients.
We will post an update every two hours. If you have any questions, please contact the IT Service Desk.
