What to do when your username is not your email address in Microsoft Outlook
My username on iMAP email accounts isn’t my email address, but for some very annoying reason Microsoft Outlook 2016 & Outlook 365 insists it should be!
If you’re having the same issue follow these (hopefully) simple steps to help you manually setup your iMAP account with your own username.
Step 3 – find Outlook Mail
In the top right hand corner search Control Panel for mail, and click Mail.
Step 5 – Email Accounts
Click New… and you will then see Auto Account Setup. If you know all your iMap account settings, use Manual setup.
