You may be able to change most of these settings before applying any exchange 2003 service pack. After applying Exchange 2003 SP2, return here to tweak any new options and features added with the service pack.
1. Open Exchange System Manager.
2. Right click the Exchange Organization and select Properties. On the General Tab, check the box to Display Administrative Groups, and clear the box next to Display Routing Groups. Click OK.
3. Under Global Settings, select Internet Message Format and in the second window right-click Default and select properties. Go to the Message Format Tab and Select the MIME and the Both radio buttons. On the Advanced Tab select only:
Exchange rich-text format:
Message text word wrap
Enable the following check boxes:
Click apply, Click OK to close default message format properties
4. Under Global Settings, right click Message Delivery and select Properties.
5. Under Global Settings, right click Mobile Services and select properties.
a. Under Exchange ActiveSync, check these boxes:
Under Outlook Mobile Access, check these boxes:
You should try clearing the box Enable unsupported devices (until you have users with mobile devices that requires this to be enabled).
There are additional items to consider when Exchange SP2 is installed. Return to this section if you want to enable mobile Device Security by enforcing complex passwords on device, etc.
Close Mobile Services Properties.
6. Add new mobile carriers to Mobile Services. Right click Mobile Services and select New and click Mobile Carrier. Under Name, insert a name for the new carrier, like Sprint PCS. Under SMTP domain insert @sprintpcs.com and click APPLY and click OK.
7. In Exchange System Manager, expand Recipients, Select Recipient Policies, and right-click Default Policy and select Properties. On the Email Addresses Policy Tab, insert the smtp addresses for Generating Mail Box Addresses of Recipients in the Organization. For example, click new and Select SMTP Address, and insert an address like @mx1.yourdomain.net or @yourdomain.net and click OK. There should already be an SMTP policy for @yourdomain.lan, as well as an X400 policy you should NOT edit. Make sure you check the box next to each new SMTP address to enable that policy.
Here, you can also SET AS PRIMARY the single SMTP address for outgoing mail from accounts within the organization. It is recommended that you use the registered Fully Qualified Domain Name that the organization will use on the internet (for example, use .com, .net, .org, .edu, etc. domain names, and not your .lan or your .local).
Answer Yes when the Alert box Asks whether you want to propogate those new SMTP policy changes by applying them to existing exchange email box accounts.
8. In Exchange System Manager, expand First Administrative Group, expand Servers, and right click your server name and left click properties. The Tab RPC-HTTP does not appear until Exchange 2003 Service Pack is Applied. At that time, if this is a one-box server, you will click the radio button next to RPC-HTTP back-end server. You may be able to set it as Not part of an Exchange managed RPC-HTTP topology. THIS NEEDS MORE STUDY. It works as an RPC proxy when RPC-HTTP back-end server is selected. Careful, not sure what if any is reversible here.
9. Under Servers, Protocols, SMTP, right click Default SMTP server and select properties.
10. In IIS, Default Website, Exchange Virtual Directory, Go to Properties, Directory security tab, Under Secure Communications section, click Edit button, and Check the boxes next to Require Secure Channel (SSL) and Require 128-bit encryption. Under client certificates, check Ignor client certificates - even though it all seems to work even if you check require client certificates (and no clients have certificates). Click OK, Click Apply, click OK to exit Exchange Virtual folder properties.
11. In IIS, Default website, RPC virtual directory, Properties, Directory Security Tab, clear the Enable anonymous access check box. Check the 2 boxes one next to integrated Windows Authentication and one next to Basic Authentication (password is sent in clear text). When queried by alert box, click yes to allowing passwords sent in clear text, and next to Default domain, type in the pre-windows 2000 secondary NT-type domain name (without a primary domain dot suffix). An example would be MSN, not MSN.com or MSN.lan. Click OK, click APPLY, Click OK to Exit RPC virtual directory properties.
12. Note, change nothing in RpcWithCert virtual directory.
13. Remember to restart the IIS Admin Service and its dependent services. Start, Run, Services.msc, Open, right click IIS Admin Service, and Left-Click RESTART, and also Click Yes when asked whether you also want to restart the listed dependent services.
