Hello,

We're receiving the following error when attempting to associate an e-mail with a customer record when that e-mail contains an attachment. In this case, the attachment is a Word document (.DOCX). I have confirmed that the extension does not appear in the blocked extension list for attachments (Settings -> Administration -> System Settings -> General) and that the size of the attachment is less than the maximum file size allowed for attachments (Settings -> Administration -> System Settings -> E-mail). The attachment is around 100KB and our attachment file size limit is set to 32MB. We're using on-premise CRM 2016 with server-side synchronization. Any insights would be greatly appreciated.

"The message was saved as a Microsoft Dynamics CRM email record, but not all the attachments could be saved with it. An attachment cannot be saved if it is blocked or if its file type is invalid."

Hello,

Can you verify that your max file attachment size is set for 32MB? It is under System Settings->Email (see screenshot). The entry you should have there for 32MB is 32000. I know I've come across this where people mistake the value for MB when in fact it is for KB.

Please verify.

Were you able to resolve this issue? We're seeing the same error on some incoming case emails in 365 on prem since updating to 8.2.2 last week.

Hi Guys,

Did any of you manage to sort out this issue? It's happening on our On-prem CRM as well.

We still have an open ticket with MSFT about it. In the meantime, we figured out that the emails that had attachments stripped were addressed to both a queue/case-creation email address AND a CRM User. We set the Incoming Email for the Users to *Microsoft Dynamics 365 for Outlook* instead of *Server-Side Sync or Email Router,* and we haven't missing any attachments since then, but it halts User ability to track emails, so is not a good or permanent solution.

Hi,

In our case, we found the issue to be permissions Access Rights: Create Access for the entity Activities for the owner of the received email.
