Configure Thunderbird for 0ffice365
Account and MFA ready?
Before connecting to Thunderbird to Office365, you need to have your MFA token/app configured.
If you use an app or SMS, then you can set it up directly at Microsoft. Note that when you select the app and use "Use verification code", then you can also use 3rd party OTP apps.
For all the options check out the internal knowledge base article
Software Installed?
The package thunderbird needs to be installed before starting.
Import PSI TLS Interception CA Certificate
Inside the PSI network access to E-Mail services using IMAP is protected by automatic malware scanning.
You get the certificate in a zip file and unpack it.
Open Thunderbird. If this is your first account, it will show a account setup assisant which you can exit or close.
Then open the hamburger menu at the top left and select "Settings".
There type certificate into the search box at the top left. Then press below the "Manage Certificates..." button.
Here click on "Import..." and then select the previously downloaded and unpacked file "cert_PSI_FW_SSL_Scanner_TRUST.crt".
Now tick the checkbox "Trust this CA to identify websites" and confirm this and the previous dialog with "OK". Finally close the "Settings" tab.
Configure Your Mail Account
To add a new account open the hamburger menu on the top left. There choose "New" -> "Existing Mail Account...".
Here please enter first the full name (as it should be shown in outgoing emails) and your email address. As no password is used yet remove the "Remember password" tick and go on by clicking the small "Configure manually" link, which opens more options below:
For "INCOMING SERVER" set the "Hostname" to outlook.office365.com, the "Port" to 993 and select SSL/TLS in the "Connection security" dropdown if that does not happen automatically. For "Authentication method" select OAuth2.
For "OUTGOING SERVER" set the "Hostname" to smtp.office365.com, the "Port" to 587 and select STARTTLS in the "Connection security" dropdown. For "Authentication method" select OAuth2 and then finish by clicking on "Done".
This is followed by a Microsoft login page where you need to enter your normal PSI AD/Windows password, maybe asking for second factor authentification (Authenticator app or token code).
With successful authentication you then close the "Account Setup" tab and enjoy the inbox or use one of the direct links for further configuration tuning, for some of them see the next two chapters.
Use O365 Default Folders
Thunderbird and O365 use by default different folders for sent and deleted messages.
Via the hamburger menu at the top right open the "Account Settings" window.
Folder for Deleted Messages
Then select for your account "Server Settings" and there select the "Deleted Items" entry in the dropdown menu "When I delete a message: Move it to this folder:".
This only needs to be done once, because after Thunderbird has marked the folders once on the server any other Thunderbird instance connecting to it will automatically use the correct folder.
Folder for Sent Messages
O365 seams to automatically put on server side a copy into the "Sent Items" folder, so Thunderbird does not need to do so. Go to "Copies & Folders" of your account and untick below "When sending messages, automatically:" the "Place a copy in:" option.
Best you send now a test message and check if you get a copy in "Sent Items".
