Portal Issue - Attachment extension failed whitelist policy

(0) ShareShare
ReportReport
Posted on by 2,822

Hello everyone,

We're using D365 CRM Online with Dynamics Portal online. Challenge what we're facing is on the attachment of the files?

If we're attaching any images or pdf then all works fine. But, if we attach *.doc, *.xls or *.xml files as attachment, then we're getting exception 'Attachment extension failed whitelist policy'.

We verified at Admin - System Settings - Set blocked file extensions for attachments and .doc, .xls or .xml is not part of it. If we manually add these extension files in D365 records it get attached perfectly.
Your input is appreciated. Thanks.

Following is the configuration:

    Hi Zohaib

    I noticed you also posted your question in the PowerUsers group, I am just linking here as you marked the solution there: powerusers.microsoft.com/.../666661

    we are trying to push people more to that forum for Portal related questions, so I guess if you have any further questions you don't really need to post it here
