Dear community, I am using Thunderbird with a rather big IMAP Email account on two different Windows-11-computers. All emails are available on the machines. When searching for certain terms, usually not all emails are found. I have for example ordered a new Ryzen CPU earlier this year and got an order confirmation with "Ryzen" in the email text. When searching for "Ryzen" this email is never found but one much older email containing "Ryzen" is. When doing the same exercise with Outlook with the same email account on the same machine, four correct hits are returned. The issue can be reproduced on both Windows-11-machines and my Android phone with Thunderbird for Android. I have already deleted global-messages-db.sqlite, but this did not solve the issue. What else could be the reason for this issue! Thanks a lot in advance! Claudius
