We recently encountered an error with an online instance of Microsoft Dynamics CRM 2015 Update 1, where the web interface was hanging when trying to change the absolute URL of a SharePoint Site record. The progress spinner would say “Saving…” and would just keep spinning without a result or any error.
Microsoft support is still looking into this error. In the meantime our workaround was to write a little console application using the CRM SDK to change the value.
// var sdk = connect to crm...etc Entity update = new Entity("sharepointsite"); // guid of the sharepoint site you'd like to update update["sharepointsiteid"] = a.Id; // by setting this to true you'll set all other records to false update["isdefault"] = true; update["absoluteurl"] = "enter new absolute url here"; sdk.Update(update);
