Hi, I do not see my Sent Folder in 4 of my 7 POP3 accounts. I have used Thunderbird for all my email accounts for ages. I was running 52.9.1 (32 bit) on an old Windows Vista Computer. I moved to a Windows 11 computer and installed Thunderbird 115.2.0 (64 bit). Importing did not work but I read the work around of copying the C:\Users\MYNAME\AppData\Roaming\Thunderbird Folder from the Vista Computer and pasting it into C:\Users\MYNAME\AppData\Roaming\ on the new computer. I also had to delete: cert8.db, key3.db, secmode.db (all obsolete), pkcs11.txt (did not exist), session.json, xulstore.json. Thunderbird came up with all my email accounts and I thought, all my emails. I thought I saw SENT email but now do not know for sure. I had to put in the passwords and my address books. I recently sent an email and noticed that there was no Sent Folder in 4 of the 5 accounts I have with my website provider. None of my old sent emails show in those accounts either. I have two Hotmail accounts set up as POP3 as well. They have both my old Sent emails and the ones I send now. All accounts are set to delete after 14 days, so any old emails are from the back up of the old computer. I went into Troubleshooting Information and under Application Basics, I opened the Profile Folder. I go to the MAIL folder and see folders for the different emails. I see a ‘Local Folder’ and then mail.mywebsite.com, mail.mywebsite-1.com, mail.mywebsite-2.com, mail.mywebsite-3.com folders for “my website” emails, and pop.mywebsite.com folder and pop-mail.com and pop-mail-1.com folders. They all have Sent files and Sent.msf files. The Sent files are of reasonable size like 100,000 kbs. The pop.mywebsite.com folder and pop-mail.com and pop-mail-1.com folders all display a Sent folder. The others do not even after I send an email but the sent and sent.msf file show the new date and time for the file, so I think they are updating. How do I get my Sent emails to show in Thunderbird? Thank you for suggestions.
