Hi, I am customizing Exchange provisioning using FIM. I have done with creating a mailbox .but it throws error"Invalid data" -ExchangeGuid when i try to open mailbox propeties of the user. In my sychronization rule i am populating the below values. HomeMDB mailnickname email MSEXCHSERVERNAME are attributes populated. Thanks in Advance Regards, Sridhar

I would start by reviewing this article: http://technet.microsoft.com/en-us/magazine/ff472471.aspx You need to flow: DN, mailNickname, homeMDB, and msExchHomeServerName (for 2010). Also, compare the format of the attributes you are populating with an account that works properly (perhaps one that was provisioned manually). While troubleshooting, hold in the AD connector space until you've reviewed the attributes to ensure that your rules are populating them correctly before exporting. Chris

Thanks Chris.. Error got resolved by enable the Exchange provisioining in AD management agent at Configure Extension. Regards, Sridhar
