[SOLVED] Could not setup free/busy interop with Exchange

[rdronov]

Hi all,

I would like to ask your help with Zimbra - Exchange interoperability.

My configuration is:
- one Zimbra 6.0.5 Server (NE),
- one Microsoft Active Directory domain example.com,
- one Exchange 2003 Org,
- common SMTP-domain - @example.com for both Zimbra and Exchange.

I've searched all available documentation and I've made all requirements from here: Free Busy Interop for Exchange - Zimbra :: Wiki.

There is an issue with free/busy availability of Zimbra users from Outlook client which is connected to Exchange server.

The other question is how to control and push free/busy info to Zimbra and to Exchange (because there is a time gap between calendar event creation in Outlook and it's availability for Zimbra users in Appointment->Schedule).

Regards,
Roman

After some research I've found that:
- users with Zimbra mailboxes could view availability of Exchange 2003/2007 users (I have second test bench with Zimba and Exchange 2007),
- Exchange 2003/2007 users could not view availability of Zimbra users.

It looks like misconfiguration or software bug.

My step by step setup is:

1. create service account with mailbox in AD domain - zimbrafb@testorg.local;
2. give zimbrafb@testorg.local client permissions 'Owner' for Free/Busy public folder 'EX:/o=TESTORG/ou=First Administrative Group';
3. check that IIS logging is enabled on Exchange server, enable log4j.logger.zimbra.com=DEBUG;
4. create contact with mail address for every Zimbra mailbox (in fact all my users are in Active Directory, and for access to mailboxes in Zimbra server users use AD authentication);
5. setup F/B Interop in Zimbra Global Settings

zimbra@zs01:~$ zmprov gacf | grep zimbraFreebusyExchange
zimbraFreebusyExchangeAuthPassword: *******
zimbraFreebusyExchangeAuthScheme: basic
zimbraFreebusyExchangeAuthUsername: zimbrafb@testorg.local
zimbraFreebusyExchangeCachedInterval: 60d
zimbraFreebusyExchangeCachedIntervalStart: 7d
zimbraFreebusyExchangeURL: http://ex01.testorg.local
zimbraFreebusyExchangeUserOrg: /o=TESTORG/ou=First Administrative Group

6. setup F/B Interop in Zimbra Domain Settings

zimbra@zs01:~$ zmprov gd testorg.local | grep zimbraFreebusyExchange
zimbraFreebusyExchangeAuthPassword: *******
zimbraFreebusyExchangeAuthScheme: basic
zimbraFreebusyExchangeAuthUsername: zimbrafb@testorg.local
zimbraFreebusyExchangeCachedInterval: 60d
zimbraFreebusyExchangeCachedIntervalStart: 7d
zimbraFreebusyExchangeURL: http://ex01.testorg.local
zimbraFreebusyExchangeUserOrg: /o=TESTORG/ou=First Administrative Group

7. add Foreign Principals for Zimbra accounts

zimbra@zs01:~$ zmprov ga s.marshak@testorg.local zimbraForeignPrincipal
# name s.marshak@testorg.local
zimbraForeignPrincipal: ad:s.marshakZimbra

8. then I make an appointment from user s.marshak@testorg.local to some users in Exchange (for example, o.fomina@testorg.local)
9. there is IIS log (time in GMT format)

It looks like everything should be OK. As I understand logs - some info writes into F/B folder. However, Exchange users could not see Zimbra users availability yet.
I appreciate any help from community and developers to resolve an issue.

At the end, I've found a solution and it is very funny.

Regards to 'Zimbra Web Client User Guide. Release 6.0' (page 107), you should check option 'Exclude this calendar when reporting free/busy times.' for your calendar. If it is enabled, external users (Exchange users) could not see free/busy information from your calendar.

I wish that information helps other people save their time setting up Zimbra/Exchange interoperability.
