After the last firmware update, my HP Color LaserJet Pro MFP 3301 no longer scans to email successfully. Instead, in the due, I see an error with "Maximum attachment size exceeded".
After doing research, I have verified my mail server does not have any limits on size. I have reset the printer to factory defaults, restarted it, and tried reducing the scan size to the minimum, changed the file type, set maximum compression, and still the same error.
I did see in that I could set a maximum file size in the mail server section, but it was on unlimited. I have tried changing that and still the same error.
This used to work fine, until the last update. What is going on with this?

Figured it out. I needed to delete the email server and re-add it. Not sure why, but that fixed the problem. How stupid.
