The integration works fine most of the time: from the CRM 2011 On Premise interface i am able to create folders in SharePoint Online and upload my documents to those folders.
After a while though, instead of proposing to create a new folder in SharePoint Online to store the documents for new records we create in CRM, we are greeted with a different window asking to create a folder in SharePoint and then enter the url in CRM.
When I check the document management settings the site location says "validation failed" but when I rerun the configuration-wizard everything works again like before.
- The url for SharePoint was not deleted
- The system still knew for which entitities in CRM document management in SharePoint was activated before
I have no idea what could be causing it, any helpful suggestions would be appreciated.
