At 3:15 PM on May 7, 2015, I received Verizon's email announcing changes to Verizon's email incoming and outgoing servers, and warnings that after June 9,2015, I would not be able to access Verizon's email unless I made the prescribed changes. As no information was conveyed as to when it would be appropriate to make these changes, I assumed (bad idea) that it should be as soon as possible. Fearing the worst, I dove in and made the changes as described in the email, and, true to form, my email no longer worked. Fortunately, I had the foresight to make note of the previous settings and could restore my email service. Then I went to the suggested links in the email to get more information on changing these settings, and, to my surprize, the handler that I use (Mozilla Thunderbird) was not included in the list of mail handlers. I find it hard to believe that Thunderbird is so infrequently used that it doesn't rate notice by Verizon's programmers.
So, please tell me when it is safe to make these changes, and, while you're at it, try to include Thunderbird on your list of change aids. Thanks.
