Dear Sam Simon
I have tried to install the Update Rollup 23 for Exchange Server 2007 SP3  as u recommend but it gives me error message as attached , I see it is related to OS installed as i have Windows server 2003 on this mail server , how I can solve this case .
I hate to be THAT GUY but why is the company still on Windows 2003 and Exchange 2007, which both have been end of life for some time?

2003 and EXCH2007 is very very obsolete, as MidnightOne says. The escape route is freakin easy - look for either O365 og a migration to Exch2013.
Other than that - in regards to ciphers, Ivan's got your back.

Unfortunately now I am responsible for this site , i know all versions is obsolete and now i am working to upgrade it server 2016 and exchange 2013 with fortimail , but for now i need to find a solution till get the required hardware
Back up the system and exchange DBs now if you haven't already. I highly recommend two different media (e.g. tape, USB/SATA attached disk) for this before proceeding.

Is the Windows 2003 OS itself fully patched? If it's not, patch the OS until there's nothing left to install. Reboots will be necessary.

Next, you'll need to get your hand on Exchange 2007 SP 3; this can be found at - once that's installed, you should be able to install the update rollups.
