We've been having issues scanning to email recently from our Sharp Multifunction Printers "network timeout errors". I just happened to find the answer on youtube of all places. It seems that Office 365 changed their logins to only accept the latest TLS1.2 connections. Something to keep in mind if your having email issues with devices that are not updated frequently. I've had to call support for a firmware update of our printers.

Hello Any help will be greatly appreciated, the admin department are breathing down my neck about this. We have set up a scan to email on a canon printer using an office 365 SMTP server, when the scanned document is sent; the printer says authentication error. When i test the SMTP connection in the canon admin console i get this: SMTP authentication (SMTP AUTH) error. Check that [user Name], [Password], and the other settings for [sMTP Authentication (SMTP AUTH)] in Authentication/Encryption Settings are correct. Please help Thank you

Hi All, Our scan to email for all printers has suddenly stopped working along with notifications that we receive from various systems. From what I have figured out it seems to be a problem with SMTP in O365. We are using Kyocera printers for the most part and when I use the very helpful SMTP test connection feature it comes back that the connection is OK. However when we send a scan to email it just simply never arrives at the mailbox. I can't see it in a message trace either. Everything I have tried has not helped at all so far. We do have a domain that also uses Gmail so I tried changing SMTP setting to Gmail and sending to a gmail account and it all works perfectly. However if I try to send a scan using the Gmail SMTP settings to an O365 account it still never arrives. I have checked our spam filtering in O365 to see if it is getting stuck there but I can't see anything there. In Gmail I did have to turn on use less secure apps setting to get it to work but is there a similar setting in O365 somewhere that could be stopping them coming through. I had assumed that if there is a similar setting that when I run the SMTP connection test in the printer it would have failed? If anyone has had a similar issue or know of a fix I would be forever grateful! Cheers

Hi, We use the PaperCut scan to email functions on a fleet of Sharp copiers, and its worked great for years. Recently scans and emails from PaperCut have started getting blocked by SpamHaus XBL list l can manually allow the external IP in this XBL list, but it then gets blocked again after a few days. I manually allowed to get it to work again, then looked at an sent email header. I think the cause is the HELO=printserver.domain.local rather than being the external Public IP that's being used. This is what is described as the issue in the XBL IP lookup. I've contacted PaperCut support but they suggested it's a network config problem. I've tried making a few changes to the PaperCut config - We use Office 365 and I remember it being a pain to set up in the first place but has been working for years. I have no access to the network config of the external IP addresses as that's at our ISP. I can't find any way of setting the HELO in the email config of PaperCut Does anyone have any ideas, how to permanently resolve so scanned emails work again without me often having to keep modifying a SpamHaus list?
