Hi, Can you please have a look at the following problem: I decided to re-index my mails. after I realized that the search results did structurally not contain any messages from 2026. I deleted the global-messages-db.sqlite. However, this did not lead to the desired result. After processing some folders, I can see in Activity Manager that the indexing stands still after having processed about 20% of the "Sent Mail" folder of a gmail account. I waited more than 12 hours, but the number of indexed messages did not increase. The file size of the global-messages-db.sqlite at this moment is only 2.3 KB, while the original database was more that 300 MB large. I already tried the following without success: # restarted TB # deleted the database for the second time # restarted my PC # repaired said "Sent Mail" folder I am running Thunderbird 140.9.0esr on Windows 11. Many thanks in advance for your replies. Thomas
