Select the messages you want to delete In the Thunderbird inbox, click on the first message you want to delete, then hold the Shift key and click on the last message in the group you wish to delete. This will select all messages in between.

I appreciate the response of AzZA, but I had already selected those groups of messages as they suggested. The messages do disappear from the inbox list, but the inbox tally remains the same. That is also true when I delete and then empty the trash. Either --the messages don't go the trash and/or --there is some less obvious place that also has to be emptied.

Any other ideas would be welcome. Carol Sibley
