The Microsoft Exchange server reported 0x80190194 the operation failed

First thing I think you need to check if you are having similar issues are

• Check application logs to see if anything pertains the same issue
• Find out what database the users is residing in ( problems user) and check the PF folder database ( is it pointing correct server )
• Offline address book , can you create another one and let it replicate and use this new one on this DB to see if this resolves the issue?
• Go to properties of OAB , make sure Version2, and Version 3 , enabled, public folder distribution enables and correct PF server is in there

If you are still having troubles

• Delete the files under ( C:\Program Files\Microsoft\Exchange Server\Client Access\OAB )
• Create new OAB
• Restart the Microsoft Exchange File Distribution service and make sure the OAB is got generated on the directory mentioned above.

You can also keep watching application logs, increase the diagnostic logon if necessary on the CAS servers.
