Thunderbird 5 and Lightning for Enterprise Calendaring and Email
I have used Thunderbird for at least 8 yrs and used Mozilla Mail built into Mozilla/Netscape before that. When the company started using Zimbra for email, IM, calendaring, Lightning never quite worked correctly. With v5 of Thunderbird, the integration to Zimbra with Lightning is working well. After using it about 2 months, I haven’t seen any failures – even on complex calendar settings.
Thunderbird v5 + Lightning Installation Steps
These instructions are for Ubuntu, but probably work with other distros too.
sudo add-apt-repository ppa:mozillateam/thunderbird-stable sudo apt-get update sudo apt-get install thunderbird xul-ext-lightning
