Hello, let me tell you that I have a few hundred email filters defined, and they (almost all) work fine. There are three filters that cause problems, and it looks like the problem sticks to the sender. Let me expand: FAZ, REWE, and Campact cause problems. Two out of three emails from these senders can't be moved to the target folders. I get a pop-up messeage telling me that I have to repair the folder. I do so, and a few days later the same problem comes up. Just for these three senders. I searched all folders for filters for these three and removed all filters I could find. Then I created a new folder as a child to the inbox folder, and a new folder inside of this folder to hold emails from FAZ. I defined a new filter rule, as the old ones were removed. Worked for a few emails, and, voila, the message pop-up came again, telling me there are problems moving the email over to the (new) target folder. Let me repeat: all other filters work fine, just emails from these three senders cause problems. Any idea where I could have a look, a switch to check? One last information/idea: all three have different email addresses they send from, I will check the ones that do not work, maybe there is a clue. I am using POP3/SMTP, not IMAP. Hoping for a tipp, a clue, an idea - Georg
