Can't download attachments using the MS CRM 2011 Outlook client

Question

Hello,
I am trying to Open/Save Attachment (from Notes in Meeting Entity) in MS CRM 2011 for Outlook Client. Once I click on attachement nothing happen.
Both CRM Server (On-Premise) and Outlook client are UR13. Its ADFS deployment.
I've tried solution here:

But didn't helped.
From log files I can't get any answer:
I can download file using direct link in web browser. Also there isn't problem when downloading from CRM web app.

Thx for response Daniel.
Attachements are stored directly in CRM DB (in Annotation table).
I have also tried fiddler. And it looks response was OK (200). I think its problem with CRM for outlook client.
