Information and procedures for the migration of Exchange servers to OGo.
TODO: More general info, maintainers wanted, contributors wanted!

We currently need people with Exchange experience who can fill this section. Required are all kinds of information on extracting Exchange data into plain text or structured files.

Exchange and OpenGroupware.org do not map to each other one to one. Exchange has features which OGo doesn't include by default and the reverse.

Specifically a large group of people use Exchange only for sending and receiving emails, not for calendaring, contact management or task management.
So to fully replace Exchange you also need an email server like Cyrus or Courier.

The "problematic" versions of Exchange are all versions up to Exchange 5.5. Exchange 5.5 isn't built upon the "WebStore" technology used in Exchange 2000 and 2003 and has no open protocols to access the storage.
So dumping information from Exchange 2000 is relatively easy by using the WebDAV protocol while Exchange 5.5 and below are hard because we need to collect information on MAPI based export tools.

We'll setup a mailing list on demand.

Notes:

Export as CSV: Outlook can export any folder data (be it in Exchange 5.5, or locally) as CSV and in a multitude of other formats. In the case of Contacts you can import such CSV files using WebUI. In all other cases you can use the XML-RPC API to import CSV files in a bulk way.
CSV Importer Example

Copy using ZideLook: If you have a ZideLook copy you can just drag-and-drop or copy-and-paste contacts, tasks or appointments from a local or Exchange folder into a ZideStore folder.
That way you can also clean up your folder structure during the migration.
