Hi,
we use Dynamics CRM 2011 on-premise and Sharepoint 2013 online and since last week CRM integration with Sharepoint stopped working. When I want to set up "Document Management Settings" in CRM administration I got an error
"An error occured while loading the page. The url may not have been mapped in the Sharepoint server. Ask your system administrator to check the Configure alternate access mappings settings in Sharepoint central administration."
But we use Sharepoint online, so I can't configure it.
I think it is common issue after some Sharepoint update in last month, because I tested 2 instances of Sharepoint online with 4 instances of CRM on-premise (3 different versions of CRM 2011 and one last updated CRM 2013).
