Outlook 2010 Synchronisation

  rts2 18:04 15 Jan 2011

I have just started to use Microsoft Outlook 2010 on my new Windows 7 computer. (The Computer was built to my spec by Arbico Computers here in the UK). I have Microsoft Office 2010 Home and Business Edition on my machine. When Outlook loads I get the following error message:- "Outlook Synchronization is not a valid Office Add-In"
Once I click "OK" to acknowlege the message, Outlook appears to work happily and sends and receives e-mail messages from my ISP, which is Orange in the UK.
What does this message mean please and how can I stop it appearing each time?

Thanks John for your suggested link. Although it related to Outlook 2000 it did enable me to disable the add-in. But relief was only temporary, because the next time I opened Outlook 2010 the error message was back - and so clearly was the rouge add-in.

Any other suggestions for eliminating this problem would be much appreciated

Try running MS Office Diagnostics to see if there isa problem with the installation.

Thanks Woolwell for the suggestion.

Have gone through the Outlook Trust Centre and confirm that the option

"Download a file periodically that helps determine system problems" .... is already ticked.

Is that what you meant by MS Office Diagnostics?

Just realised that office diagnostics has been removed for 2010 version. But you can still repair click here

Thanks Woolwell for your continuing interest.

Took up your suggestion about letting MS Office repair itself. Software went through the routine successfully, but when I loaded Outlook again, I got the same error message about Sychronisation!

Quite a persisent little add-in this one!

I don't run 2010 but what is your anti-virus? Wondering if it is an e-mail scan.

Is there anything obvious in the trust center list of add-ins? Or indeed anything that shouldn't be there?
