Nagios2759671) # - MS-ASProtocolVersion: 12.0 (Exchange 2007 RTM) # 14.0 (Exchange 2010) # 12.1 (Exchange 2007 SP1) # 12.0 (Exchange 2007 RTM) # # Parameters: # $1 - domain name # $2 - username # $3 - password (Note: avoid using of special character e.g.: escalation mark!) # $4 - DeviceID - A unique id for the device that is synchronizing (you gen retrieve that information from owa (Outlook web access)) # or using power shell: # Get-ActiveSyncDevice -Identity "user" # Get-ActiveSyncDevice -Mailbox "domainuser" # $5 - DeviceType - An id for the device/model you are using, or the ActiveSync client.
