This message can be triggered by flawed Add-Ins from Third Party manufacturers. Outlook Add-Ins from Third Party manufacturers can hinder communication between SimpleSYN and Outlook.

Known problems: You may receive this message if you have the Apple Mobile Device Support Add-In installed, which is automatically installed by iTunes. The Add-in may make the PST file unusable for other applications when Outlook is shut down. Then SimpleSYN will also no longer be able to access the PST file.

To avoid the problem do not close Outlook while SimpleSYN is running.

If you are not using iTunes to synchronize an iPhone/iPod with Outlook, you could also deactivate the Add-in in Outlook.
