Hi. I'm using Outlook 2013/Office 365 on Windows 7. I like to answer emails while working offline so that I'm not distracted by incoming emails. Problem is, when I go back online, some of them leave the outbox and some don't. When I click the Send button, some go to the outbox with a date in the Sent column. Those will leave when I go back online. Some go with None in the Sent column. Those will not. Please advise. Thanks in advance.
