CRM cannot retrieve some E-Mails from the Exchange Server (Server-Side-Sync)

I had this issue before (see: https://community.dynamics.com/crm/f/117/t/306079) but now it is different. The CRM did not retrieve sometimes E-Mails that are waiting in our Exchange mailbox. First we thought only SMIME E-Mails are a problem, but now it also happens for E-Mails that are IPM.Note.

Here is the error we found in the log.

I did a test and simulated this E-Mail with the .Net SmtpClient. This E-Mail was retrieved by the CRM. See EWS-Editor:

crm_2D00_missing_2D00_emails.png

(from top to bottom)

  1. A E-Mail from the customer that was not retrieved before (5)
  2. SmtpClient Test with same sender address as the customer has.
  3. E-Mail from the same domain but send by his colleague.
  4. Same as 3.
  5. Missing E-Mail, sender like in 1.

If I could simulate the problem I could enable the verbose trace. But it only happens sometimes and I have no clue why it does happen. We already updated CRM to the latest version 8.2.5.0004 in the hope that this would fix the issue.

    Ok, I made some mistake. The E-Mail that could not be synchronized by the CRM was received before we did our update. I just asked if my colleagues can give me a newer example. Maybe the update fixed it already.
