For a number of months now some of our users receive the Microsoft 'Server Busy' Switch to.. Retry error when opening Outlook 2007. The full message states 'This action cannot be completed because "" program is not responding. Choose "Switch to" and correct the problem..
Our environment is as follows:
Server 2008 OS
Outlook 2007 mail client
Hosted desktop on Citrix XenApp 5
There is never any entries in the event viewer logs relating to this prompt. When the user clicks 'Retry', it usually goes away however it is obviously annoying and sometimes requires the user to click 'Retry' a number of times before it disappears.
I understand this prompt occurs when an application is open and tries to make a network connection before a network connection has been established. This is not the case for us as the users have logged in to a Citrix sesssion before Outlook is open, and hence a network connection has obviously already been made. It seems to happen to different users at different times, some with and without additional PST files in their profiles..
Any idea's on the cause of this and how to fix it? Is it purely a network issue with Outlook being slow to connect to Exchange?
