Microsoft Exchange Login

You should usually be able to log in via Exchange using your email address and password. If you have two-factor authentication enabled on your account, you'll need to generate an app password, and you can use Microsoft's instructions for how to do that. If you see an error message, you should try one of the following things.

Specifying a username

If your email address (eg. is not the same as the username you use to log on to Windows, try entering your Windows username in the ‘Exchange username’ box. It may look like an email address or be in a DOMAIN\username format, eg.NYLANAUTS\tony:

If this box is left empty, your email address will be used.


Specifying an Exchange server

N1 auto-detects most Exchange server names, but sometimes you will need to enter the server details manually.

If you have access to Outlook Web App for your email, the server name you see when logged in is the correct one. For example, this Office365 user sees when logged in:

If you're in doubt, ask your Exchange server administrator about the exact domain name of your company server.


Connection issues

If you are sure the details are correct but login is failing, this may be due to connection issues. Please make sure you have not entered a server name that requires VPN access.


Extra help

Sometimes the username and server details are all correct, but syncing an account still fails. This is rare and we recommend you contact support with a detailed description of the issue you are experiencing.
