I just uninstalled and reinstalled Thunderbird and recreated 5 accounts - 2 Hotmail and 3 Gmail. Two of the Gmail accounts work fine however one does not. It has two issues:

1) I get the following error when trying to send an email from it: Sending of the message failed. The message could not be sent using Outgoing server (SMTP) smtp.gmail.com for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again.

2) it only has an inbox folder - no other folders associated with it

This is all the same when running TB in safe mode.

Thanks for the reply. I'm not sure I totally understand -

All the Gmail accounts (2 working and 1 not) were setup by Thunderbird and have smtp.gmail.com for the outgoing server and all the parameters I've looked at in all 3 accounts are the same except the User name and email address.

I noticed an additional related issue - when I click on get messages, a message appears in the lower right hand corner of the screen saying "The current operation on "Inbox" did not succeed. The mail server for account (the one that doesn't work) responded: Unknown command .......)"

Something really squirrel y is going on. I first checked in Gmail if the account was a POP acct. I found it was indicated for both POP and IMAP so I unchecked POP and the account was able to send. So, I did that for all the Gmail accts. then all but a different one could send. It seemed I'd fix one and another would quit working.

I then insured they all were pointing to a different Outgoing Server as you said. That also would work for a while then another random account would quit. I then changed them all to use the Default Outgoing Server and they all are now able to send messages. However, two of them still do not have any folders but Inbox and they both receive the "Inbox error" above when I Get Messages.

I am on TB 52.2.1

Any more ideas?

Thanks again!
