I use Thunderbird on Mac OS 10.14 (Mojave), server is Orange. My account on Orange was referred as POP. I recently transformed it into IMAP ant it works OK. On the IMAP account, I created the same e-mail address than on the POP account, and I wish to keep it. Now, can I suppress the POP account without loosing my address ? In the Thunderbird help, it is said that : if I suppress the POP account, I will simultaneously loose my address. But it is the same as on the new IMAP ! What should I do ? Thanks for any help (in French, or in English).
