https://support.mozilla.org/en-US/kb/archived-messages recommends not archiving more that 2000 messages at a time but doesn't say what might happen if you do. This issue is worth reporting upstream to Mozilla (I haven't found anything relevant there yet). Your original report just said "large numbers of messages". Approximately how many? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1387439 Title: achiving large numbers of messages is slow and leaves context menu on- screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1387439/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
