Diagnostic Steps
Resolution in Edit in Office or Edit Document feature opens a blank document in Microsoft Office has already been attempted.
Cause
SSL is configured on the Confluence server. Confluence uses WebDAV to provide the Edit in Office functionality. WebDAV requires the client to send a certificate. If the client does not have a certificate, the server and the client can negotiate for other authentication mechanisms. See https://support.microsoft.com/en-us/kb/954809 for more details.
Resolution
Import Confluence's certificate following Microsoft's KB: Import or export certificates and private keys.
