where has my toolbar gone and how do i get it back , on e-mails, i cannot see 'file' 'options' or anything. i now need to have read receipt on some emails i send but cannot find any toolbars? help
The top message in the inbox is automatically marked as read when Hotmail is opened. I would prefer all messages that I haven't clicked on to stay "unread", until I have actively selected them. Is there a setting to achieve this?

Every time I leave and come back to Outlook 2011 some of the messages "marked as read" become "marked as non read".
If I select them and do a click right to select "mark as read" nothing happens... I have to "select all" then click on "mark as non read" and select all again and click "mark as read" to get them "marked as non read" but often when I leave and come back to Outlook 2011 some of the messages "marked as read" become "marked as non read".
It's just terrificlyboring.
Thanks for your help.
