Imperial does not yet support the new version of Outlook for Windows. Guidance and further information will follow when it falls under support.

Check which version of Outlook I have.

We recommend that all members of the college use Outlook to access their emails. Outlook can be accessed from the web, or a client can be installed on your desktop/laptop, Mac, iOS or Android device. Outlook is pre-installed on College devices for easy access to your emails. 

For better security, we recommend you use Multi-Factor Authentication (MFA)

Note: Thunderbird v78 or higher supports MFA. iOS 11, iPadOS 13.1 and macOS 10.14 and above native mail client supports MFA. Some older email clients don't support MFA. Please check the vendor's website to see if they support modern authentication - some are able to with if you set up an App Password.

Please be aware that while we will endeavour to support Thunderbird, it is not a core college service and therefore we cannot guarantee stable use.

Steps for fixing known errors

If after clicking Done, your email does not appear, please try:

  • In the Tools menu, you will find Options. In options, there is a button called Attachments.
  • Please locate the association for the file type and delete it.
  • Next time you ask Thunderbird to open a file of that type it will ask you what to do with the file. You will need to select the correct application. You can also click Save and have Thunderbird remember exactly what to do with that file type.

If the attachments are being removed from emails then please try the following:

  • Currently there is an add-on that allows the attachment to be displayed, which comes directly from Mozilla

If you want to sync your contact, task and calendar information with Thunderbird then you can try using a TbSync add-on. Download the add on from Mozilla.
