Synchronize Zimbra and Exchange calendar

[kaltera]

Hi,

I'm trying to synchronize calendar from Zimbra to Exchange as I'm currently in Beta mode and my contacts are still using my Exchange account to have access to my free/busy information

Do you know if it can be done easily wit imapsync ?

I did not manage to make it work but I saw that it was possible to sync calendar from Exchange to Zimbra so the way back could be possible ?

Anyone already tried to do this ?

regards
