SBS Exchange 2003 mail sitting in Outbox...

We are running Small Business Server 2003, with SQL and Exchange installed.  Exchange was running fine for approx. two weeks then suddenly stopped sending receiving mail.

Users can now no longer send externel or internal mail to each other.  They just sit in their outbox forever. Running Outlook 2000, with all service packs and office updates installed.

Looked in the Event Log and now see an error that I had not seen before.    It says:  Initialization of external interface SMTP failed;  Error ecVersionMismatch-MAPI_E_VERSION  When I click on the more information link it talks about checking the latest service pack is installed, which it is.  Then starts on about msExchMaxThreads and msExchMinimumThreads values are set correctly.  Thought this must refer to a registry setting but couldn't find any?  Where do I find this setting and what are the correct values?  It says the default values are 100 and 10.

Or if any other things could be stopping the mail would appreciate knowing.

Some other things you might need to know:
Connected to internet via ADSL router/firewall, which is our DHCP server.

Any further help much appreciated.

Thanks,

Neil.

Please copy/past the entire Event log message, including event id. And the event id just prior to the error you are getting.

The event log gives the following:
Initialization of external interface SMTP failed; Error ecVersionMismatch-MAPI_E_VERSION. with Event ID of
9542.

The event ID prior is 100
Microsoft Exchange OLEDB has successfully started.

I'm a bit lost with this.

Okay, what's the symbol for being really stupid?  

Decided to reinstall Service Pack 1.  Went to the folder I'd extracted the files to and saw a seperate ADC folder, which had a i386 folder in, with a setup.exe file.  As I hadn't run that the first time ran that, then ran the update.exe from the other folder and hey it all now works.  I just don't remember anything saying there was a need to run the setup file?  Guess I missed something.

Anyway appreciate all the help here.

Thanks,

Neil.
