In Thunderbird, select Tools > Account Settings > Account Actions > Add Mail Account
Enter your Name as you wish it to appear
Email address (firstname.lastname@example.org)
Password (This is your IT Services password)
Thunderbird will then try and be clever and discover the server settings..... it will fail!
You can then manually change the settings
Incoming: IMAP outlook.office365.com port:993 SSL/TLS Normal password
Outgoing: SMTP smtp.office365.com port:587 STARTTLS Normal password
Username: email@example.com (This is your IT Services username)
When you have added the information select the Re-test button, when it is happy with the settings the Create Account button will be made available.
The basic setup is now complete.
There are some additional settings which allow for a better integration with the email system and will add sent and deleted email to the correct folders on the server, therefore if you use another client the information is retained in the same location.
Before we can continue we need to show all of the email folders.
Right mouse click on your new WBS email account and select Settings - Server Settings - Advanced
Untick Show only subscribed folders
When you select okay all of your folders should appear in the left hand column
Right mouse click on your new WBS email account and select Settings - Sever Settings
Select the "When I delete a message:" and tick "Move it to this folder" then select Deleted Items
While you are in the Account Settings menu select Copies & Folders, under "When sending messages, automatically:" click the other radio button and select Sent Items from the @wbs account
Thunderbird is now setup.
