An SSD crash had forced me to rebild my Sys from scratch. In course of this exercise I too updated Thunderbird and mananged to reconnect my old prfile file.
Now TB won't download e-mail from web.de any more. Not unless I go through ... see my Moz_TB_01.png - which in Turn will trigger an error message ... see my Moz_TB_02.png
If I click create excemption for this rule he will download the e-mail, but (even though selected) this excemption is not stored as default / automatic.
Apparently the issue is driven by a Security-Certificate (or other provider specific informations) which are not correct or not handled correct.
Does this mean I should download the Certificate ?? Where to store it ?? how to register it with TB ??
Any help / advise appreciated
