I am not able to find the reason for this happening. Is there anyone who has any knowledge they can share on this topic?
We have done the following to try to fix the problem:
- restarted the Email router service
- disabled/enabled the profile in the Email router
- deleted the e-mails in question from the POP3 mailbox
- deleted an re-created the queue in CRM and re-loaded in E-mail router and restarted the service again
Any other ideas?
