Cannot recive e-mail: message registry error

[Cerry]

After backing up my hard-drive, when I switched on Outlook 2003 I received a
message that there was an error in the Registry for extension "Exchange
Extensions" syntax or format and informing me that I should check the
registry settings and compare this extension to other extensions in the same
registry.

I have no idea how to respond to the message.

The effect seems to be that I can now send but not receive e-mail. I am
told that error OX 800 CCOF is occuring.

Please help!

 

[FRUSTRATED TO THE BITTER END!!!]

have you double checked your settings for the receiving server address? it
might have gotten erased in the process that you were doing (accidentaly of
course) try double checking your server address, run a test and make sure
that it is correct. if it isn't then you will need to input the address again
for it into your outlook 2003.

hope that helps
