I've started getting this message recently when trying to open a store in online mode.
Code: MAPI_E_FAILONEPROVIDER == 0x8004011D
Function CallOpenMsgStore( lpMAPISession, (ULONG_PTR)m_hWnd, lpEntryID, ulFlags, (LPMDB*)lppMAPIProp)
File MainDlg.cpp
Line 435

I think this may have something to do with 2-factor authentication they just enabled on our accounts.
