Setting up Windows, and

Setting Postbox with Windows, and email accounts

  1. In Postbox, go to File > New > Mail Account.
  2. Enter your full name in the Your Name field.
  3. Enter your, or, or address in the Email Address field
  4. Enter description in the Description field (can be anything).
  5. Enter your email account password in the Password field.
  6. Click Continue.
  7. You are now back at the Account Settings screen. If Postbox automatically pulls POP settings when setting up Hotmail account, change them to IMAP with the following:

Incoming (IMAP) Server

  • User name: Your email address
  • Server address: (some customers report faster response times with
  • Port: 993
  • Encrypted Connection: SSL

Outgoing (SMTP) Server

  • Server address:
  • Port: 587
  • Authentication: Yes
  • Encrypted Connection: STARTTLS

Click Done.

Note: While we strongly recommend using IMAP, shall you need to setup your account over POP, please make sure to enable POP access on under Settings > Accounts > POP and IMAP. Hotmail accounts setup over POP in Postbox must have password of 16 characters or less. This is a limitation of the Hotmail service itself, even though you can use passwords longer than 16 characters when using Hotmail's webmail interface.

Two-Step Verification

If you are using Two-Step Verification, then you must generate an app password for Postbox. 

Go to the security settings for your Microsoft account at (you will be prompted to login).

Scroll down to the App passwords section (which will only appear if you are using Two-Step Verification), and click on "Create a new password."
