Need help setting this up?
If you'd rather not deal with the technical side, we can fully set up and manage your Microsoft 365 for you — including email, DNS, and ongoing support.
1. Open Mozilla Thunderbird.
2. On the left side of the Top menu, Click on the "Write" option.
If you have multiple email accounts, click on your account and a drop-down menu will open. Then select the appropriate email and enter the email account of the person you want to send an email to in the "To" field.
In subject field, enter the subject of your email, enter your message in the message box, and then click on "Send".
