Getting Involved

The OpenChange project welcomes anyone who would like to become involved in the project. We particularly need people with an interest in (in alphabetically order, not priority):
  • bug triage
  • development / coding in C, C++, Python or Perl (and possibly other languages depending on your development goals)
  • documentation / proof reading
  • system administration (especially with Exchange servers, although other mail / calendaring / task based tools and general sysadmin support would also be useful)
  • testing and bug reporting
To become involved, we suggest you start by:
  1. joining the main mailing list (see subscription information and the archive of previous posts to the mailing list for more information)
  2. Register on the tracker and post your questions in the Forums.
  3. and if possible, also join the IRC channel we use - #openchange on Freenode (server: irc.freenode.net, channel: #openchange).

Your next stage is then to set up a development environment (either from scratch, or starting with a pre-build appliance). Guides on how to do this are provided below. If you have trouble, please ask questions on the IRC channel (preferred) or on the mailing list.

We have an incomplete list of tasks (including bugs to fix and features to implement) on the issue tracker. Please let us know what you are working on before getting too far into it, to prevent any issues coming up at merge time, and also to allow us to provide guidance / suggestions where appropriate.

Thanks for your interest in OpenChange!

ExchangeRPC Investigation

The OpenChange project scope includes both implementing the "as documented" protocols from Microsoft, and also investigating and verifying the protocol (and its documentation). See Protocol Information.

Fast Transfer

We have an implementation of the "Fast Transfer" operations described in MS-OXCFXICS. See Fast Transfer for more details.

Project infrastructure

The OpenChange project has a strong commitment to appropriate infrastructure. A description of some of it is available in OpenChange Project Infrastructure.
