PSTDisableGrowAllowAuthenticodeOverrides & PstDisableGrow with 2013

Hi

I'm getting the "a setting on your computer that controls the size of outlook data files" msg when opening outlook at a customer.

added the registry values

PSTDisableGrowAllowAuthenticodeOverrides

PstDisableGrow

both set on 1 under HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\PST as DWORDS

still not working.

Is there a different scenario for outlook 2013?

Thanks,

Sarah
