Just means that one attendee cant be accessed in Outlook. Do you use an exchange account andhave insufficient rights to access some contact folder or GAL?

We can catch the error and only log a warning in next release.

You should investige why the user has no access to the contact folder and ask your exchange admin.
Next release will be scheduled in next days.
