EWS client including Public folders support has been released as part of Rebex Secure Mail version 2016 R1.
For more details see our blogpost.
Hi, here is a new beta build with the Public Folders support. It is accessible as a EwsFolder, so basically
Ews.GetFolderId(EwsSpecialFolder.PublicFoldersRoot) are start points to go. Please note that you have to have correct access rights on your Exchange server to access the Public Folders.
Please note that since we are still working on the EWS support in Rebex Secure Mail component, the API is slightly changed from the build published on our labs page. Search support is also added in this build, but not fully tested. If you have licence to Rebex Secure Mail and want to use non-trial version of this beta build, please let us know on firstname.lastname@example.org .
