Scan to Email had been working with a CompuServe "from" account. CompuServe required me to change to an application password. I couldn't get it to pass the Scan to Email setup test. I got "Incorrect credentials". After a number of tries, I switched the "Outgoing Email Settings" to what I was using for Email Alerts. Same account, server, port, options. Email alerts work. Scan to Email setup test fails with the same setup information. It still gives "Incorrect credentials". What's going wrong?
