Unable to update Cryptopolicy object in Windows Azure Active Directory
Posted on 2014-04-03
We are in the process of moving our email to Office 365 using the Hybrid method. This has been up and running without any problems for a couple of months now. Two days ago I had to reboot the server that runs DIRSync and ever since then, every time there is a sync between our Active Directory and Azure we get the following error message.
"Unable to update this object in Windows Azure Active Directory, because the attribute [ProxyAddresses, Mail], is not valid. Update the value in your local directory services."
There are five errors all for a contact named Cryptopolicy. I have found five different contacts with this name in AD under "Program Data\Microsoft\ADFS\....." so I guess these are the objects in question. None of them have the ProxyAddresses or Mail attribute set.
Everything appears to be working OK but I am just wondering why for no apparent reason this error has started to appear and more importantly could it be caused by a more serious underlying problem.
many thanks for any information you may be able give on this.
