I have created a Google WorkSpace account for retrieving and sending emails. Within the account, I have a main eMail address shown here as "main" for illustration. "[email protected]" I have several alias sub-accounts that take the form "[email protected]" I'm seeking to be able to retrieve mail Google places in my "inbox" and/or mail filtered so as only to appear in my "SubAccount" . I've followed instructions to set up account with incoming server "pop.gmail.com" with a user name of "[email protected]" outgoing server "[email protected] - smtp.gmail.com" I've also changed permissions to allow cookies as suggested by one web site. Thunderbird asked for various p/w and automatically filled in the eMail menu with "inbox" and "Trash", but when I ask "Get Messages" , Thunderbird says "Sending of password for user "[email protected]" did not succeed. Can Thunderbird be configured to retrieve mail from Google workspace accounts. I've been successful on getting it to retrieve eMails from a regular free gmail account. I've been careful to make sure I don't get them confused.
