Personally, I prefer using a Quick Step for this scenario. To add the Mark Complete command to the Tags section on the Home tab itself see: Adding commands to the Home or Message tab of the Ribbon Quick Step Mark as Complete, Mark as Read and Move to folder
From the list that shows up, right click on the Mark Complete action and choose: Add to Quick Access Toolbar. To add the command to the QAT, click on the Follow Up button that is shown in the Tags group on the Home tab. To save yourself a click, you can also add the Mark Complete action to the Quick Access Toolbar (QAT) or Ribbon. Click on the Flag icon again to mark it as completed. This flag is shown when you hover on a message. To quickly mark a message as completed, you can click on the Flag icon that is shown in the message list. Nevertheless, when this information is important to you, you can consider flagging a message as "Mark Complete" which will add a date-stamp when the message was flagged as completed. No, this information isn’t stored somewhere.
Is this information registered somewhere in Outlook or in a log file? However, I'd like to know when I read a message that someone else has sent to me.įor instance, this would be especially useful to me for informational messages which did not require me to reply but are important enough to know when I’ve actually read it. I know I can request a Read Receipt to find out when someone read a message that I sent.
