I am also experiencing this problem. It's only Thunderbird that has problems renaming or deleting (certain) folders; other mail clients handle these operations just fine. I filed a bug against Thunderbird for this back in April but haven't yet had any response: https://bugzilla.mozilla.org/show_bug.cgi?id=1628600 Regards, Tristan -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tristan Miller Free Software developer, ferret herder, logologist https://logological.org/ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
