One of five things causes a 403 – Unauthorized error, which usually occurs when sending a certificate or storage of outgoing documents.
1. "Put" verb is not added to the aspx extenstion in IIS config of the virtual directory
2. IIS worker process user account does not have rights to the certificate directory specified in the admin.aspx or the .net temp directory.
3. After an IIS reset, attempting to send the certificate or PDF file without testing the connection to the content server first before sending the certificate or PDF file. (Order of operation should be iisreset, then test connection via OAC0, then send the file.)
4. Certificate has not been created in SAP via t-code STRUST.
5. First thing a user does upon logging in is to try to send an outgoing document. There is a script that simulates a connection attempt which runs automatically when a user logs in to prevent this from happening.
