Hi there, I have got a strange issue. To me it seems as if Thunderbird has Merged or actually lost a two e-mails. When looking at the Folder window (the window where alle the e-mails in a folder are listed) an e-mail with the subject "Referat fra vores møde i går" is listed. But, when I open this e-mail, Thunderbird "findes" a different e-mail, with a different subject and no content!!! I have tried to highlight this issue in using the red pencel in the attached screenshut. The serversettings for Thunderbird is server type: IMAP Mail Server, and I can actually find my lost mail (the "Referat fra vores møde i går" e-mail) i the mirrored folder on the IMAP server. What kind of further information can I provide to verify if this issue, actually is a problem? Kind Regards Steen Vemmelund
