Process blocked sales and distribution documents from the SAPoffice inbox

Hi,

I know VKM1/VKM3 can be used to release order.

And SAP help shows we can process blocked sales and distribution documents from the SAPoffice inbox. Could anyone tell me how?

I can use output type KRML to send a mail to SAPoffice inbox, but don't know how to release blocked sales orders in the SAPoffice inbox.

Many Thanks

Jean
