MicrosoftI'm attempting to use this method to create a username and password to send messages from an older copier, since the ability to use SMTP AUTH is gone with Security Defaults, and the service as a whole is done in 2025. The obvious issue I saw, and have run into, is that the username and password lengths are insanely long for an older device to accept. Is there a method that I can use to reduce the length of these two fields? Otherwise, this solution is no good for users of old machines. Thanks for the excellent tutorial!
(Password is 32 max, Username is 64 max on my Canon Copier/Printer/Fax)
Hi Dave, can you please check below post. There will be a private preview soon to fix this.
