My new email address through Network Solutions works fine on my phone and my desktop via webmail, but I cannot connect it to Outlook on my desktop computer despite days of trying and searching forums and talking to customer support. Initially I connected it to my computer as a POP, but the problem is that it doesn't sync across my devices. So I deleted the account and tried to set it up as IMAP via Outlook 2016, and it failed. The problem with my phone and webmail is that I only see a limited number of emails. I need to have access at all times to all my emails. If I install Thunderbird on my Windows 7, will I potentially face the same problems trying to set it up as IMAP? I don't want POP because it doesn't sync, I need my emails to sync across all devices. I am not a techie, but trying to understand all the terms that I can.
