Outlook -- Email Not Being Received or Sent, or Sent to Junk Mail

If someone at Drexel CCI says they are not receiving any email, or that they are not able to send any email, or that all their email is going to the Junk mail folder, try the following:
Removing any pre-existing rules that the user has in place (example, RULE: Move "PHISHING:" to Junk).
Then have the user check their Junk/Spam/Trash/Deleted Items folders to see if their emails are there (unless they already know where their emails are).
Also, have the user check and make sure their email isn't being forwarded to some random address.
To delete rules:
     1. Ask the user to login to http://outlook.office.com .
     2. Click on the gear in the top-right corner.
     3. Click on "Mail" in the bottom-right corner, in the sliding menu.
     4. Under "Mail" in the "Automatic Processing" section, click on "Inbox and sweep rules."
     5. Use the check-boxes to select all of the rules. Then use the Trash icon to delete them.
To check forwarding:
     1. Ask the user to login to http://outlook.office.com (if they haven't already). 
     2. Click on the gear in the top-right corner.
     3. Click on "Mail" in the bottom-right corner, in the sliding menu.
     4. Under "Mail" in the "Automatic Processing" section, click on "Forwarding."
          (a) CCI faculty and staff will likely NOT have this option.
     5. If the address is a foreign one, delete it, then click the "stop forwarding" radio button.
Have the user check their Spam/Trash boxes to see if their mail is there. They may have to manually select and move any emails to their inbox if they find their emails there, unless you know of a tool or quick way to forward email from specific addresses in one fell swoop.
