Hi Kevin,

As you're on Exchange 2003, either will do. If it's Exchange 2000, you're stuck with the 6.0.x product.  If it's Exchange 2010, only SMSMSE 6.5 will work. 

I recommend examining the material about what's new in SMSMMSE 6.5 (Exchange Server 2010 Support / VMware and Hyper-V Virtualization Support / Enhanced installation error dialogue with web links / Quarantine Notification enhancements / 24% reduction in install package size / Customizable logging enables disk I/O reductions / Premium Antispam Enhancements with Memory and CPU throttling to reduce the impact to server / Fastpass expedites processing for good senders, improving throughput by up to 15% / Local Reputation collection adapts protection to local conditions). Full details can be found in the Release notes for Symantec Mail Security 6.5 for Microsoft Exchange

 If there is a feature there that you will require, use 6.5.  If not, stay with 6.0.10. 

Please let the forum know what you decide to do, and add any information that may be helpful to a future mail admin who is trying to make the same 6.0.10/6.5 decision!

Thanks and best regards,

Mick

Thanks Brett!  I will make sure that gets fixed.

I have a 64-bit Windows 2003 server running Ex2007.  SMSMSE 6.5 is installed and working fine.  There is absolutely no requirment to migrate to Windows Server 2008.

Thanks and best regards,

Hi Brett,

I really would not recommend having MS Outlook installed on a server OS.  Servers should not be used as a workstation for word processing, mail reading, etc- and definitely never to surf the Internet, as so many threats can infect a machine by drive-by these days. 

My quick test here verifies that SMSMSE won't install onto a server that has the MS Outlook mail client installed.  I don't know of any way around that, unfortunately, and it's probably getting into unsupported territory by trying to shoehorn it on there.

The best advice: uninstall MS Outlook and let the server act as a dedicated mail server.  If that same physical machine must absolutely also be used to access mail, then use the OWA (Oulook Web Access, the webmail that Exchange can serve up) or the lighter Outlook Express. 

Thanks and best regards,

Mick 

hello, don't know regarding 6.5, but the upgrade process from SMSMSE v5 to v6.0 is giving a little problem:
- be care of the advanced "auto-protect" options.
Normaly both are disabled by default, (as documentation told), but curiously, upgrading from 5.0 activate both, all the same was previously not in v.5:

• scan message bodies
• force rescan

If you are 20 mailboxes, no problems, if you are 2'000, can get a problem !!!
That's fun because, if install from scratch, both are deactivated !

Mark this if solve or help !
