I can only pick one from EMC, maybe there is a pwer shell CMD to enable both auth at same time?TIABoGot it:Set-OutlookAnywhere -Identity:"CAS01\Rpc (Default Web Site)" -ClientAuthenticationMethod:NTLM,Basic

Permissions are specificto virtual directories.You're correct, though -- you have to use a cmdlet to set bothauthentication scheme becasue the UI only lets you select one.Use "help *virtual*" to find the correct cmdlet.---Rich MatheisenE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

Hi, You can use Set-OutlookAnywhere command with IISAuthenticationMethods switch to enable both NTLM and Basic authentication. Thanks,Mike
