We're having an issue on some (not all) Email accounts. When configured to mobile (Android or iOS), it will not sync. On OWA and Outlook are working fine. Tested with Microsoft Connectivity Analyzer, shows, "Attempting the FolderSync command on the Exchange ActiveSync session. The test of the FolderSync command failed.".
One email account reported the same when trying to setup to the new mobile phone. The weird thing happened is from his old phone, email account is configured and working well till now. Incoming/Outgoing is working well (old phone). When I check with Connectivity Analyzer, same issue I got, FolderSync command failed. Viewed on Exchange, Manage Mobile Phone, no device listed like other has.
Some email accounts (like mine and other I knew) are working fine with mobile, OWA and Outlook. Also tested with Microsoft Connectivity Analyzer, "Attempting the FolderSync command on the Exchange ActiveSync session. The FolderSync command completed successfully."
We have Exchange 2010 (Exchange Server 2010 Microsoft Corporation Version: 14.03.0382.000) on Windows Server 2008 R2 Enterprise SP1.
Anyone can help us here? What might be the caused of the problem? Please note that I have checked the inherent permission under Security Tab on AD. And for the Virtual Directory on IIS? I doubt if there's an issue cause not all having the same.
