Two copies of Tbird on same PC?
I have three email accounts. One arrives on desktop via Tbird, the other two by Outlook. There are three different servers--local ISP, Gmail, and Outlook 365 (GoDaddy email). At least in Outlook I have to set a default server, and if I send from the other account without changing the server designation, the email either does not arrive or is dumped in spam. I am assuming the same is true for servers in Tbird. Can I use a second copy of Tbird somehow, or must I find a third email client? (Windows Mail will not work for this.) Thanks.

You can run a single copy of TB with multiple accounts in a single profile, but it's necessary to align each account with an smtp server that has the same User Name. Failure to send is often a result of not setting up the accounts in this way:

It's also possible to have accounts in TB and other mail clients, or on multiple devices, as long as the accounts are IMAP everywhere.
