SOGo Outlook Free/Busy information

Development
1

Hi,

I’ve been wanting SOGo’s free/busy info to show up in Outlook for a long time. I finally wrote something.

It requires sogo-tool to get every users calendars, libical to generate freebusy info. I borrowed code from Citadel to get libical to generate the free busy info for me.

It’s a single C++ file. Simply compile with g++ and link with libical.

I have it running under NethServer and generating new freebusy files every 15 minutes, then scp’ing the final files to a web server where Outlook can find them. Certain things are hardcoded into the source:

const string SOURCE_DIRECTORY = "/root/sogo/" ;  // location of sogo-tool backup files
const string VFB_DIRECTORY = "/root/vfb/" ;      // location of final freebusy files
const string DOMAIN = "xxxx.com" ;           // domain for ORGANIZER information

Is anyone interested? What should I do with the source?

Gerald

Excellent work!

I think you could propose an upstream patch :wink:

And how would I go about doing that?

That’s the right place:

Hello Gerald,

was this code disseminated somewhere? There is some issue currently with free-busy on sogo and repeated events and it would be nice to have a look at your code to see if it could be used instead.

The code is nowhere, as far as I know. I basically run a script from crontab that runs sogo-tool backup
into a known directory, and then I run my code. The script and code
(with makefile) are attached. You will need libical installed.
I run this code once an hour, and Outlook is happy with what it
generates (uploaded to a web site for Outlook to access).
There’s no license attached to the source.

Hello Gerald,

Thank you very much for your willingness to help!

Unfortunately it seems that Discourse stripped the email attachments…

Cheers

Hmmm. Ok, I’ll put the file somewhere else and post here when it’s available.
