How To Fix Email Settings in Outlook 2016 / 2013 / 2010

If your email account has stopped working, an update or crash may have caused some settings to change. This guide will take you through the email settings so you can go through and fix everything up.
Before you start:
A) Make sure you have the correct email settings for your account. Click here for a guide on finding your correct email settings. Other than the username (Email Address) and password, all settings will be exactly the same for all email accounts on the same domain.

Step 1 - Click on FILE

Then click on the Account Settings option (click Account Settings, then click the next box named Account Settings)

 
Step 2 - (1) Select the account you want to fix, then (2) click Change

 
Step 3 -
(1) The Email Address and Username should both show the full email address
(2) Incoming and Outgoing mail server should be the same
(3) If your password is in there, keep it as it is. Come back to this and re-add the password if your email still fails after checking the other settings
(4) Make sure the "Require logon using Secure password" box is unticked
(5) Click More Settings

 
Step 4 - Make sure the "My outgoing server" box is ticked, and "use same settings as my incoming" is selected. Click on the Advanced tab one this is set.

 
Step 5 - Make sure the Server Port Number and Root folder path settings are the same as bellow. The port/encryption settings are universal (every email service in the world uses these same numbers). Click OK once that's done.

 
NOTE: On rare occasions, due to some network settings on your router/firewall/office network, the SSL settings above don't work. If you continue having problems, try these settings instead

 
Step 6 - Once that's done, click Next > Outlook will set your email.

 
If everything is correct, you'll see something like this.
