Earlier this morning, Microsoft Outlook was experiencing performance issues. Users may have found their Outlook clients to run slow or crash repeatedly. As of 11:45am, Microsoft has applied a configuration update to resolve this issue, but impacted users may still need to take an extra step to fix their experience:

• Outlook client and app users should restart their client or app to apply changes. Outlook desktop client users may need to perform this action twice due to caching issues. 
• Outlook on the web users should refresh their sessions. If that does not mitigate the issue, users are encouraged to clear their browser cache and refresh their Outlook on the web session.

Users may notice Outlook using an increased amount of system resources, causing the client to freeze or crash. This may also be impacting the performance of Outlook web access (https://uomail.uoregon.edu) and Outlook mobile apps. Microsoft is working to restore service.

External mail delivery has returned to normal behavior. All queued messages have been delivered. Information Services staff are continuing to monitor and investigate the root cause to prevent recurrence.
