Here is how I find TPG email address CAN be configured in MS Outook 2010 with SECURE settings for POP mail - it really works. Have been using this successfully for several years! (I do not reember from where I originally obtained the information some years ago, and cannot thus far find it online - and I cannot find it so far in anything TPG have published online).   Here is how to get the job done with secure settings - it works with me on 3 computers, so I expect it should work for anyone): *In Outlook, select to add a new Account. *Put information into 1st screen, then ensure to select "Manually configure server settings...etc" (Do NOT try to let Outlook find the settings online - I have NEVER had success with auto set-up.) *USER NAME - the first part only@ of your TPG email address, i.e. all BEFORE the @ sign (NOTE: the full TPG email address will NOT work when I configure Outlook, but info above does work!) *POP =  mail.tpg.com.au   - and - SSL = 995 *SMTP= mail.tpg.com.au - and - TLS = 587 *Outgoing Server - Put tick in box beside "My outgoin server (SMTP) requireds authentication."  (which in turn will automatically put a "dot" in the cirlcle immediately below where is says, to the right of it, "Use same settings as my incoming mail server" - and should that not happen, then select "Use same settings as my incoming mail server". *When configuration is completed, click OK. *Then click on "Test Account Settings" to confirm the account will send and receive. *Logon Info - Put dot in circle beside "Use same settings as my incoming mail server"   (This has proved to me again that "all things computer" need to be accurate - the slightest deviation from what works means that it will not work.)     Kudos to: @Chazo   Looking forward for more knowledge that you'll share with our Community. :) I can confirm that the above settings actually work on Outlook 2016 and 2019 with a few modifications as per the attached screenshot. You can access these settings after you disable office365 simplified account creation (Microsoft article here: https://support.microsoft.com/en-us/help/3189194/how-to-disable-simplified-account-creation-in-outlook)   After so many tries, this finally did the trick and the outgoing mail server connects!
