OAuth 2.0 Microsoft - Token error randomly

All,

In preparation for SMTP AUTH getting turned off next year, I have set up the OAuth 2.0 (Microsoft) setting in the four Canon MFP's we currently have.  One machine, a Canon iR-ADV 529, will scan to email fine for about one week, then stops.  Remoting in shows a "token error", so we have to disable and enable the OAuth 2.0 function again, re-authenticate using the User Code, and it works...for about a week.  The other three machines do not do this and work without issue.

I know refresh tokens are valid for 90 days.  Does the MFP communicate with Office 365 before the 90-day mark to get a new token automatically, or will this require us to remote in to do these every 90 days?

Reaching out to our service vendor, they state "Not much else out there other than to redo it when it happens. I'm beginning to think it isn't a reliable service, but we have no control over it. Scan to Folder is the other option you can do."...I'm working with the remote site to further troubleshoot, but outside of this one MFP, I am starting to think something on-site could be an issue.

Thanks for joining the conversation, rmarkwald!

While our forum community members are welcome to chime in, Canon does not provide direct support for imageRUNNER series products. Instead, your dealer will be able to help you!
