Description
                        
                        
                            The Secure Mail application is draining battery excessively for XenMobile managed devices
                         
                     
                    
                    
                    
                    
                        
                            
                                
Resolution
                            
                            
                                1) Define the XenMobile server as an STA over port 8443 within the NetScaler Gateway
2) In the MDX App Settings for Secure Mail, please configure the following:
- The first is “Background network services” – this should be the FQDN of your CAS/Exchange server with a colon and port. i.e. “cas.mycompany.com:443”
- The second is “Background services ticket expiration” – this specifies how long the STA ticket is good for in that STA ticket table for XenMobile
- The last is “Background network service gateway” – this should be the FQDN of your NS or AG VIP. i.e. “ag_vip.mycompany.com:443”
Problem Cause
STA configuration for Secure Mail supports long-lived connections and gives us better battery life compared to mVPN
