Current status of USPTO systems
M365 Outlook service has been restored.
Users that come online will notice an initial delay in retrieving email, but that is likely to be minimal since no one was able to connect or send email during this outage.
If, after restoration of email, a user experiences an additional Outlook problem, please use the IT Service Portal to report the issue.
