Thunderbird is changing the sender when I try to send emails

Hi, I've had two different gmail accounts for many years, and both are being accessed via Thunderbird. Both are set up to work with OAuth2, and I have OAuth2 settings in Outgoing Server settings. I've been able to receive and send emails with both accounts until this morning.

Starting this morning, every time I try to send an email from one of the accounts (the one starting with 'ce'), it changes the 'sender' to my other gmail account (the one starting with 'mc'). This is causing any emails sent to email lists where I'm registered with the 'ce' account to reject my emails, because the sender shows up as the 'mc' account.

I've tested the effect by using the gmail web access page (Chrome, Win7) and sending emails to an email address with a different provider, and the sender field does not get changed.

Any ideas on how to cure this problem?

Many thanks,

Charlie

I have the same sort of issue. I can send emails from my phone or the gmail server with no issues. But if I send from Thunderbird (on my laptop), no matter which account I try to send from, the sending email address is being changed. This appears to have something to do with the outgoing smtp settings. When I change any of them, that change (sending address) is applied to all the accounts. Can't seem to locate how to set each account to use it's own independent address. Used Thunderbird for years with multiple gmail accounts, but never had this issue until recently.
