My PC crashed last week and had to be reset. In attempting to restore Thunderbird, I am attempting to set it up as if it was a new account. Default address (Swisscows) and Gmail address set up flawlessly; however, 2nd Swisscows account results in an error message: "Incoming server already exists." I am assuming this refers to either the default address or the pre-crash incarnation of Thunderbird. Either way, I am unable to set up the 2nd Swisscows address--which just happens to be the address I use for work. I would appreciate any guidance. (BTW, I did not have my Thunderbird backed up to another file.) Thanks.
