I am unable to add new accounts to my outlook 2010 or even a data file, basically anything through the account settings.

On attempting to do so I receive the following:

'There was an error locating one of the items needed to complete this operation. It may have been deleted.'

I have done an install of all office items and then reinstalled, installed all patches but still the same.

Has anyone seen this before an any advice on how to resolve the issue?
