Microsoft uses a lot of propriatary protocols in their products, which makes it sometimes hard to work together in projects. This document describes how to integrate the Open Source e-mail and calendering application Thunderbird with the Office365 product. For the e-mail part we can use the standard IMAP and SMTP protocols. For calendering however we have to rely on a Add-on written for Thunderbird.

IMAP

• Server Name: outlook.office365.com
• Port: 993
• User Name: your e-mail address
• Connection security: SSL/TLS
• Authentication method: Normal password

SMTP

• Server Name: smtp.office365.com
• Port: 587
• Connection security: STARTTLS
• Authentication method: Normal password
• User Name: your e-mail address

Add the following add-ons to thunderbird:

• TbSync
• Provider for Exchange ActiveSync

After installation select in the Thunderbird menu, Add-ons.

and then TbSync

From the drop-down menu Account actions select Add new account and select Exchange ActiveSync.

In the new panel select Office 365.

The account name is something you can choose yourself, the e-mail is the address belonging to the account you want to add.

Tick the boxes you want to synchronize
