We have been using Zimbra Collaboration Suite, with the Zimbra web interface as well as Thunderbird, in our office for over a year. Ever since the Zimbra server was installed, we have had a problem with the Drafts folder not correctly reflecting unread status or, sometime, content number. This happens with everyone's account.
Everything I read says it can be fixed by expunging (compacting) folders in T'bird but this isn't working for us after repeated trials. Is there any other way to correct the problem?
