I followed the documentation on setting up exchange 2013 and SharePoint 2013 for task synchronization. When I try to sync the tasks to outlook, i get an error telling me that the user mailbox on exchange may not support task synchronization. when i look in the ULS logs in sharepoint i see the following error:
An operation failed because the following certificate has validation errors: Subject Name: CN=localhost.localdomain Issuer Name: CN=localhost.localdomain Thumbprint: 5D64E20B424D4A613288024734CAD805A1BD7B0E Errors: SSL policy errors have been encountered. Error code '0x6'..
Problem is i don't know what certificate this is reffering to. Has anyone seen this issue before or can give me any advise on tracking down this certificate? the cn=localhost cn=localdomain is confusing to me.
