Probleme bei Umstellung von POP auf IMAP
Subject: Thunderbird 152 – IMAP Junk messages are not automatically moved to Spam (T-Online IMAP) I am using Thunderbird 152 on Windows 11 with a Deutsche Telekom (T-Online) IMAP account. Problem When I manually mark a message as Junk (toolbar button, context menu or Junk column), the message briefly disappears from the Inbox and immediately reappears. It is marked as Junk, but it is not moved to the Spam folder. If I disable the option "Move new junk messages to:", the message remains in the Inbox and is marked as Junk, without the brief disappearance. Manual Move to → Spam always works correctly. Environment • Windows 11 • Thunderbird 152 • T-Online IMAP • ESET Internet Security • Only one Spam folder exists on the T-Online server. Troubleshooting already performed • Created a completely new IMAP account. • Verified Junk settings. • Verified the Spam folder path: imap://...@secureimap.t-online.de/Spam • Manual move to Spam works correctly. • Rebuilt the folder cache. • Recreated folderTree/folder cache files. • Performed IMAP resynchronization. • Tested with ESET mail protection enabled and disabled (no change). • Checked profile configuration. • Verified that the IMAP server directory setting does not change the behaviour. Additional observation The profile contains two IMAP cache directories: • secureimap.t-online.de • secureimap.t-online-1.de The current IMAP directory does not contain local Spam/Junk cache files, while the old "-1" directory still contains: • Spam • Spam.msf • Junk • Junk.msf Thunderbird also displays a greyed-out, inaccessible Spam/Junk folder which cannot be selected, subscribed or removed. Question Is this a known issue in Thunderbird 152 related to IMAP Junk handling or old IMAP cache migration after changing an account from POP to IMAP? If not, which log or additional information would help identify the cause?
PS: The POP account worked correctly before the migration to IMAP. The problem started only after switching from POP to IMAP. Rudolf.weinzierl-landshut@t-online.de

Hello there Rudolf weinzierl landshut.
Yes, I read your message. These issues often happen if the connection with the server is poor at the moment you try to connect. Yes it is a known issue in version 152.0 .
Repair folder 'I think you have damaged folders, so you can try to repair them. Just right-click the damaged folder, select Properties, and click the 'Repair Folder' button.
Temporary disable the antivirus software Temporarily disabling the antivirus is a good way to troubleshoot. If the described issues disappear, try adding the software to your exclusion list
Troubles with the connection to the server might cause those famous phantom or ghost folders. It also causes the greyed-out data.
Tip If you are using antivirus software, it might lock the email database as Thunderbird tries to move items, resulting in failed moves.
Text Resubscribe to the IMAP Folder (Un-hides Ghost Folders)If a folder is greyed out, it often means the mail client has lost sync with the email server.
Right-click the name of your email account in the left folder pane. Select Subscribe>Click the Refresh button. Look for your Junk/Spam folder, make sure its checkbox is checked, and click OK
Cause Switching from POP to IMAP. Having trouble with the server connection.
