Subject line on some emails causing Error code 29

(0) ShareShare
ReportReport
Posted on by 55

Hello all,

We have Dynamics CRM on-prem v8.2 with exchange server side sync setup. We have 3 queues setup for our customer service department, we noticed that some emails aren't getting though to these queues and the trace record shows 'Error Code: 29', no detail in the text.

I have been testing with the emails that are failing and can see a lot of them appear to be RE: or FW:, I have played around with these and have managed to get the emails to be created in the system only if I change the subject of the email. I cant see what would be causing the subject to block these from being created, there is no correlation between any of the subjects.

Some notes:

- I've turned off Smart Matching to no affect

- The emails I've looked at, a previous email in that chain had already been created in CRM

Has anyone experienced this in the past or can see from above what could be causing it?

    Hi,

    Do you have any custom logic on email send?

    Did you notice since when this issue started, Any recent deployments or server patches, etc?

    Try restart async services, that may help
