I am setting up three email addresses in a new Windows10 system. The first attempt (IMAP) worked ok be following instructions in my Krystal hosting account. When setting up the second address, I got the incoming mail port number wrong but outlook still added the address in the left column. Because I didn't spot my mistake, I tried a few times which failed until I realised my mistake. However I now have several copies of the same email address in the left column. When I click 'file' then 'account settings' I have the option to delete the working address but the incorrect ones stay in the left hand column. Anyone know what I'm doing wrong? If I could, I'd totally uninstall outlook and start again but I can't even do that.
