Hi.

I'm facing a issue where i'm trying ti figure out why moving users between 2 OU's will grey out the Sign button in outlook.

There is a valid signature and all i need to do is just move the OU and it works. 

So my questions is which policy / registry setting can control this? I know it probably can be more but i am hoping someone experienced the same and can point me somewhere. Been trying for days now myself and just cant work out which policy it is. 

Hi,

Would you please specify what "Sign" button in Outlook 2010? We'll appreciate it if you can provide a screenshot to help us understand the issue. You can share the screenshot regarding this issue to us by sending it to GBSD TN Office Information Collection  ibsofc@microsoft.com. (The email subject should be the thread link)

Thanks,
