Not sure about this but since we migrated to exchange 2010 we are getting this sync issue all the time. I checked around the Eforms Registry folder and the subfolder both have the default permission for Reviewer. But when I try to Get-PublicFolderClientPermission “\NON_IPM_SUBTREE\EFORMS REGISTRY” I get an error that No existing 'PublicFolderEntry' matches the following Identity: 'NON_IPM_SUBTREE\EFORMS REGISTRY'. I checked outlook and the org. library form that we have used is there and working. Just want to address the error - assuming this is the problem. Any ideas? 15:03:21 Synchronizing Forms 15:03:21 Downloading from server 'exchange.mydomain.com' 15:03:21 Error synchronizing folder 15:03:21 [80004005-501-4B9-560] 15:03:21 The client operation failed. 15:03:21 Microsoft Exchange Information Store 15:03:21 For more information on this failure, click the URL below: 15:03:21 http://www.microsoft.com/support/prodredirect/outlook2000_us.asp?err=80004005-501-4b9-560 15:03:21 Done 15:03:26 Microsoft Exchange offline address book 15:03:26 Download successful

An issue many have. As far as I know, still no fix in sight: http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/e2ca3480-0855-4822-bc42-3747a4bd1b1d/
