When clicking on the Add to Method icon in Outlook on a sent mail I get the following message:
 
"Value cannot be null. Parameter name: uniString" with the only option a white x in the top right or OK. both behave the same.
 
After up updating to SP1 for Office 2010 I got a "serious" error with Method Outlook Integration. Asking if I want to remove it from Outlook enabled Addin's. At the time I selected No.
 
I have since done an uninstall from the control panel, a remove from Outlook 2010 32bit Add-ins and a reinstall and restart.
 
Nothing is working.
 
Thanks for your help.
