I wonder if somebody can point us in the right direction.
We have Exchange 2003 and a mixture of Outlook 2003 and Outlook 2010 clients. Yesterday, we experienced an error by two Outlook 2010 clients which is shown as Msg.png in the attached zip file.
It would appear that if Allow is chosen, the message clears and the user is able to use Outlook successfully. However, if Outlook is closed and re-opened, the message reappears regardless of whether "Don't ask again" is checked or not.
If Cancel is chosen, the message disappears temporarily, but appears again at random intervals making Outlook 2010 unusable.
Now today, we have had another Outlook 2010 client exhibit the same problem.
All Outlook 2010 clients were installed using "Manually configure settings for Exchange Server" as auto-configuration is not available with Exchange 2003.
Any ideas how we can prevent this message from appearing and, perhaps more importantly, why it is suddenly occurring in the first place? Will we start getting this message on more and more users machines?
Any help would be appreciated.
