“Send to” Function not working properly in SharePoint 2010?
I recently had an issue with a new install of SharePoint 2010. A user was trying to send/copy documents between libraries on the site, and the “send to” function was not available, it was grayed-out. After a little research, I found that there is an add-on in Internet Explorer that can cause problems with the “send to” feature of SharePoint. To fix this problem, go to “Manage Add-ons” in the Internet Explorer tools menu. Change the view to “show all add-ons”, and disable “STSUpld CopyCtl Class”. Your “send to” should now work without a problem.
