Closed Unassigned: Mfcmapi error when trying to access public folders [16878]

I created a public folder, but when using MFCmapi and I try to access the public folder using the administrator account I get the following error:

Error:
Code: MAPI_E_FAILONEPROVIDER == 0x8004011D
Function CallOpenMsgStore( lpMAPISession, (ULONG_PTR)m_hWnd, lpEntryID, ulFlags, (LPMDB*)lppMAPIProp)
File MainDlg.cpp
Line 437

I can access the public folder in OWA, but seems my backup software won't let me backup using document level backup and I suspect this is the reason why.

Any way I can get the 0x8004011D error resolved?

Thanks
