I am trying to switch my active and working Thunderbird 116 for Mac from pop to imap. After entering name email and password in the "set up your existing email address" I recieve the green box message indicating "the following server settings were found". When clicking the blue "done" button at the bottom of the page i get the "unable to log in to the server" error message. The mail account continues to work properly with the pop settings. Are there any workarounds or solutions to this issue? Thanks!
