Source: Koen Roos blogMicrosoft CRM 2011 beta is available. I was curious about the SharePoint integration in CRM 2011. Unfortunately, the Sharepoint solution delivered with the beta release wasn''t working (I was getting errors "Could not load file or assembly ''Microsoft.Crm.SharePoint.CrmGridFeature'' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key", a reply from Microsoft CRM Support is added, saying there are some unsigned bits - http://social.microsoft.com/Forums/en-US/crm2011beta/thread/8d195290-6bfa-4d4b-a1a9-ad21bb296ad2), hope they will post an update soon!
The SharePoint solution is required to have CRM creating Sharepoint folders automatically when adding a new record. However, it is possible to add Sharepoint locations manually to a record too. Some screenshots:
