Hi, do you have a local installation of Microsoft Office? In other words, you create emails outside of your browser, in the Outlook program? In that case, you can use the old Email Link feature. As a test:

• If the classic Menu Bar is not displayed, tap the Alt key or F10 function key to activate it
• on the File menu, choose Email Link

If you haven't used this before, Firefox should display a list of different methods for sending email that have been set up. If Firefox automatically uses a method that doesn't work, you can check the setting here: Change the program used to open email links.

Unfortunately, it often does not work with webmail sites (other than Gmail) because the format in which Firefox sends the data is no longer supported by those sites. For those sites, you may need an extension to set up the connection, but I'm not sure which ones work with Office365. Does your mail site address start with: https://outlook.office365.com/owa/?
