Using OL2002 with all the updates.

Deleted a recurring diary entry and at the time got a message which I closed
(cannot remember what it said). All recurring entries now gone from Diary
BUT diary still thinks there is something present at each time (if I book a
new appt. it tells me I have a conflict even though nothing is there). Also ,
the day in question is in bold on the calender as if an item is present
(although nothing is there).

More seriously , when I try to open address book or hit to or cc buttons in
new mail I get "the messaging interface has returned an unknown error". "If
the problem persists please restart outlook"

If I go to file, data file management and settings I get following error.
"an unknown error occurred, error code 0x80040605

Any ideas? I have had to switch to an alternative mail program for now...

Have already tried repairing pst. creating new profile etc.

We also have this problem - if you remove Critical Update 921594 fixes the
problem

Description of the security update for Outlook 2002: January 9, 2007

INTRODUCTION
Microsoft has released security bulletin MS07-003. The security bulletin
contains all the relevant information about the security update for
Microsoft Outlook 2002.

Looks like Microsoft should be involved on this one

This problem persist due to the exceeded the built-in .pst size limit. You can work around this problem by allowing upgrade to large tables. If the problem persists then use the Inbox Repair Tool and create a new pst File. If problem also is not solved then you can take help of pst repair software. The pst repair software is easy to use and provides robust and powerful recovery. In demo version you can preview 5 e-mails, 20% of contacts and calendar entries from which you can evaluated the efficiency & recovery capability of software.

The problem with this issue is the mapi profile is getting corupted. Under Control Panel Mail icon click and rebuild a new Outlook profile. Once you rebuild a new profile you will be able to connect to the exchange server again and build a new copy of your mail profile. Ergo you will be able to down load a fresh copy of your address booki. This was a difficult one to solve but I proved it in 3 different enviornments so I know it is correct. Enjoy the sollution and vote yes on proposition 8

Thank you glad I could used my 27 years of experience and help all that wish it.

Once this is done you will be able to create new emails and replies because the profile Outlook will be able to authenticate with the proper msmapi32.dll in commonfiles under program files.
