It has come to our attention that the Activity Feed solution is temporarily unavailable for download from the Microsoft Marketplace (the link for the download had been: http://pinpoint.microsoft.com/en-us/applications/microsoft-dynamics-crm-activity-feeds-12884926310).

Fortunately, we had downloaded a recent copy of this for a client deployment.  If you need a copy of the file, please contact us (click here) and request the file and we will email it to you.  To install it:

1. Be sure you are running UR6 or later (we have tested it on UR8)
2. Import the .cab file into CRM as a solution

It is provided without warranty, but we have installed it in a test environment and it works without an issue.  If you become aware of the download becoming available again, please reply to this post so we can update it accordingly. 

Thanks!

UPDATE 6/11/2012: The solution is now available from the Microsoft Marketplace again.  You can now visit the above link to download it directly.  Cheers!
