This topic was originally in the Windows forum, but it was suggested to repost it here due to the open source nature of the question:




I'm looking for Calendar software for my Windows 8 PC, for a while I considered Thunderbird because it has the Lightning extension which is iCal compatible (for moving my iCal data from my old Macbook). Unfortunately it looks like Mozilla won't be supporting Thunderbird much in the future:




Open source software is preferred, so can anyone recommend a iCal compatible open source calendar program running on Windows 8?

Sun contributed to Lightning to some extent with a view to bringing it to Open Office.

Libre Office is now the preferred community fork, and discussion has occurred on bringing Lightning over to Libre Office. Therefore Imho continuing to use Lightning is not a bad bet.

Kontact (with KDE-PIM) might be the next largest project with the longest history. There is no official build for Windows but It is available for Windows from an informal maintainer. Another option would be running a VM for it.

Mozilla is saying Thunderbird/Lightning will get a new home and is laying the ground work for a transition:

Options are:

Document Foundation - home of Libre Office
Free Software Conservancy - home of Busybox, git
Mozilla - new dedicated team

Mozilla has a director in common with Document Foundation. If the time is right to move closer to Libre Office that would be amazing.

All in all it is a very safe move to continue using Thunderbird/Lightning along with the other 10-25 million users : ).

So I've been using Thunderbird recently on both my Win 10 PC and Macbook Pro and its working fine, I've been using Lightning on my Win 10 PC and just tried to use it on my Macbook Pro. All my calendar events are on the Win 10 Lightning, but when I started up Lightning on the MBP it wasn't showing any of the calendar events.


Does this mean the MBP Lightning needs to be synced with the Win 10 Lightning? There is a button on the Calendar Toolbar named Synchronize, clicking that on both machines doesn't do anything.


Both machines are downloading mail via Thunderbird with no problems so it doesn't appear to be a password issue with the Gmail server - Thunderbird is set up with POP3 and apparently IMAP is better for syncing but again this a calendar issue and not a email issue... any help here would be appreciated, thanks

I moved this to "Desktop Computing" because this is a Linux question either. Open Source doesn't always mean Linux - and this is really about desktop computing since it's not specifically a Windows thing...
