- This article is a Work in Progress, and may be unfinished or missing sections.
Note:
- These instructions assume that MS Exchange 2010 and Zimbra Collaboration Suite have been installed using the "DEFAULT" configurations. Modify wherever necessary according to your target system’s configurations/settings.
- MS Exchange 2010 System obtains Free/Busy information by using Availability Service instead of Public Folder which is used by Exchange 2003 (The Availability Service obtains the user’s Free/Busy information from its mailbox directly). However Zimbra Collaboration Suite’s interoperability with MS Exchange System is based on the “legacyExchangeDN” attribute which assumes that the Free/Busy information is published into the public folder using WebDAV. If your MS Exchange 2010 System does not have a Free/Busy folder then you can create a new one using the following Exchange 2010 Management Shell (EMS) Command:
[PS] C:\>New-Publicfolder -name "EX:/o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)" –path "\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY"
- You also need to ensure that the Exchange 2010 CAS server is forwarding WebDAV service requests to the backend Exchange 2010 Mailbox server.
I. Exchange Free/Busy Lookup from Zimbra
On the Exchange 2010 System:
1. Create service accounts on MS Exchange 2010. Name it "zimbra". 2. In the Administration console, select Global Settings in the navigation pane, and then the Free/Busy Interop tab. The Microsoft Exchange Settings page displays. 3. Set the following parameters:
- Microsoft Exchange Server URL: This is the Web interface to the Exchange.
- Microsoft Exchange Authorization Scheme: Select Basic or Form from the dropdown menu..
- Basic is authentication to Exchange via HTTP basic authentication.
- Form is authentication to Exchange as HTML form based authentication.
- Microsoft Exchange Server Type: Select WebDAV or EWS from the dropdown menu.
- WebDAV: Select for Exchange 2007
- EWS: Select for Exchange 2010
- Microsoft Exchange User Name and Password: This is the name of the account in Active Directory and password that has access to the public folders. These are used to authenticate against the Exchange server on REST and WebDAV interfaces.
- O and OU used in legacyExchangeDN attribute: Set at the global level this applies to all accounts talking to Exchange.
