I have Mozilla Thunderbird email Client on my HP W10 Computer and just have so many that I want to Save on to an External Hard Drive/Back Up on to Google Drive and so on. I do not know how to do this Process and I tried my Local Service Provider/Verizon Tech Support and they cannot help as thy said they are not Familiar with this Product. Is there anyone even for a Fee/Paid Support that can be of help to me on this? Kindly Reply to me with more Information as I Really Do Not Want To Loose All Those Emails. Yours Very Truly/Thank You, Louis Zarowin Brooklyn, N. Y. 11210 917-608-6173/800-486-9113 louiszarowin@webtv.net
