I have an old BlackBerry Bold 9780 that has been working well. However, just yesterday I started receiving an error "Cannot access local folders" when trying to use BB Desktop to sync with Microsoft Outlook 2016. I uninstalled and reinstalled the BlackBerry Desktop Software 7.1, but the problem continues. There are no errors when using Outlook or with other aspects of syncing in BB Desktop.
I am running 64-bit Windows 10 on my desktop computer. I have had no problems syncing in the past until yesterday. To my knowledge nothing has changed.
A Google search for the error message returns questions posted on several different forums, but there is no clear solution given.
