You can report spam/phishing in a couple different ways - via email to Microsoft or using the Junk Email Reporting feature. We suggest using the Junk Email report option available in both Outlook Web Access (OWA) and in Outlook desktop.
To report a message in OWA, right-click the message and select the appropriate option (see screenshot below).
You can also click the message, and select the appropriate option from the menu at the top of your screen (screenshot below).
To report a message in Outlook, open the message, select the "Report Message" in the upper right, then select the appropriate option.
If you are unable to use one of the methods above, you may also report the message directly to Microsoft via email.
Start typing "REPORT..." into your address bar, and select the desired address (screenshot below).
To report a message as legitimate and help ensure delivery in the future, select the "report as not junk" option when available. This will help train the spam filter.
