Hello. I am using 2 email accounts in Office365 and I am using Thinderbird. I can send emails from one email account which is on the Office365, but can´t send any emails from another Office365 account in Thinderbird. Settings of the SMTP server are just the same for both. I don´t understand the reason. It worked perfectly until this new update of Thinderbird. Could anybody help with a quick solution? Thank you. Katarina

Do you have 2 smtp servers defined in Account Settings, with the same settings except for User Name (email address), and is account 1 sending on smtp 1, and account 2 sending on smtp 2? Select the account in the left pane of Account Settings and look at Outgoing Server (SMTP) in the right pane to see if the User Names match.
