Hello ... I know of 4 Windows 7 computers running Windows Live Mail 2011 that all have the same problem. There is no option to turn Auto complete on and off . On 3 of the computers (one of which is mine) when you start to type in the address the Auto complete will bring up the addresses that start with whatever letters you type. On one Auto complete is not working at all. On all 4 when you go to tools/options/mail/send there is No option to check Auto complete on and off. 3 of the computers have been running Live Mail for quit sometime but the one that it is not working on is a brand new computer with a brand new Win7 Pro COA and a new install of Windows Live Mail via Windows Essentials. I found this post from Jan 2012 to be of no help ... http://answers.microsoft.com/en-us/windows/forum/windows_other-networking/how-do-i-disable-autocomplete-in-windows-live-mail/8753a3b2-5aad-4069-be5e-77e6d8b9ba4a?msgId=4f8b25ea-bf82-489b-9e23-e903df51fdbc . On 02/06/2012 it was BlownOff/ Answered by Brian Tillman [MVP-Outlook] . I found nothing about it on the ... All WIndows Live Mail questions belong here: http://windowslivehelp.com/product.aspx?productid=15 page after searching everything I could think of. I am not the only one with this problem. I called 1 800 936 5700 and Microsoft has a fix, but only if I pay them $99.00 will they give it to me. This is a Live Mail problem and no one should have to pay for the fix. The problem has been around for sometime but the Jan 2012 Question was blown off and not answered because it was posted in the wrong place. I will wait and see if the fix comes in response to this question. What happened to the Auto complete option in Windows Live mail ? If the answer can not be found here what answer would I be charged $99.00 for ?   If this question is in the wrong place I would like to know where it is supposed to go as I got here from the Windows Essentials Help page.

The same question from Jan. 2012 was also blown off from here too http://windows.microsoft.com/en-US/windows/answers?tId=8753a3b2-5aad-4069-be5e-77e6d8b9ba4a
