Freebusy sync failling with java.lang.NullPointerException

Hi,

My zimbra users are able to see free/buzy infos from my exchange server (2010 SP1).
But the one still on the exchange server are not able to see the F/B from the Zimbra users.

It seems Zimbra is unable to push change in the Exchage Public Folders.

In the logfile /opt/zimbra/log/mail.log I can see the following :

Code:

The LegacyExchange is the same on Exchange and Zimbra.
The Foreign Principal is set to the Exchange Contact.


Do you have any hints where to search ?

Hi-

After banging my head against this exact wall for several weeks, we changed the setting for the zimbrafreebusyexchangeuserorg from

"o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)"

to

"EX:/o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)"

That fixed it.

I have tried you point, it is not fixing my problem. The problem should be somewhere else.


I have finally the required accounts for the NE support .... Hope they will find the problem.

Hi Anael,

Were you able to find a solution to the problem? If yes, then could you please share the solution? I'm stuck with this problem for the past couple of days.

Thanks,
Arun.

Hi,

Unfortunately, I wasn't able to be anything useful with the logs / NE support.

It is working on a fresh installation from Exchange but not in my current production environment.
Some users weren't able to see some calendar while the migration was rolling.


I have voted on some Exchange IIOP bugs/RFE do should do the same, perhaps with more votes someone will implements theses.
