Outlook 2007 Error "Either there is no default mail client...."

[briant97]

I receive this error when I open outlook I have uninstalled and reinstalled
office and it still comes up. Error message states "Either there is no
defaul mail client or the current mail client cannot fulfill the message
request. Please run Microsoft Office Outlook and set it as the default mail
client." I have set it in IE under programs to be mail client, I have went
into tools and options and other tab and set it there also and still receive
this message. Everything seems to work fine with it and my desktop search
works fine. I just get this annoying pop up everytime I open outlook. The
following is the only solution I have found to get rid of the error message.
However this solution causes desktop search to stop functioning. It remove
Outlook complete from the default programs list for email in Internet
Explorer Options. The only way to get it back is to reinstall office is to
uninstall office and reinstall. Once I do that then I continue to get the
error message but desktop search seems to function fine. If anyone could
give me some answers to who I get rid of this annoying error message that
would be great

The first thing would be to uninstall NIS, then reinstall NIS, if you must,
before reinstalling NIS *without* outlook integration

Sorry but I don't have NIS. That was just an example of the way that I have
been able to fix it. I have been able to remove the registry keys in that KB
article from symantec to fix it however desktop search quits functioning
correctly and I can no longer setup Outlook as my default email client when I
remove those keys.

I was able to get this working by renaming the registry key that is in the
following KB article.

For some reason symantec's knowledge base was able to help me with finding a
resolution. Even thought I don't have any symantec products installed.

The main reason you get that error message is that the install of Office
was not updating the Mapi32.dll. Extract the MSMAPI32.DLL from the
Outlook cab file from the install and rename it to MAPI32.dll. Backup
the current MAPI32.dll in the system32 directory and then copy the new
MAPI32.dll into the system32 directory.

This may happen for many reasons. The main reason is that you have
another application installed that uses the MAPI subsystem, i.e.
Blackberry Desktop Manager, Exchange System Manager, etc. The office
install doesn't seem to replace the dll if there is an older version
already there.

Or just run Microsoft Office Diagnostics (in the Microsoft Office Tools
folder). Nothing popped up as wrong, but when I restarted Outlook the
pop up was gone!
