Exchange 2010 no ExchangeOAB Folder

imccoy asked
I have migrated from Exchange 2003 to 2010 and I am using Public Folders. I followed instructions in the deployment wizard, but it's not working. I get the following error in the Windows App. event log:

Log Name:      Application

Process MSExchangeFDS.exe (PID=1884). Could not find directory \\EXCH-SVR\ExchangeOAB\123a886d-006a-4f1b-9cb5-795fcd9143a6. This is normal if it has never been generated. Otherwise, make sure this directory and share has read permission for "Exchange Servers" group.

I checked the folders, and there is noe Exchange OAB folder, there is a ClientAccess\OAB folder, but no files are in it. 'Enable Web-based distribution' and 'Enable Public Folder distribution' are checked. Will manually creating the ExchangeOAB folder and setting permissions work? Are there instructions to do this?
Watch Question

I got the folder populated. Here's how. On Exchange 2010 server I went into \Exchange Server and created a folder ExchangeOAB with a new share with the following permissions:

Share Permissions:
•Administrators – Owner
•System – Owner
•Exchange Servers – Reader

NTFS Permissions:
•Administrators – Full Control
•System – Full Control
•Exchange Servers – Read

After that I started the Microsoft Exchange System Attendant service, and then updated the OAB again.

I guess I need to wait for the ClientAccess\OAB folder to populate.
