Outlook: How to Add Grid Lines Between Emails in Office 365

Recently I updated Office 365 and the Outlook emails are displayed without any line separators between mail messages. It was looking like a total mess and managing emails was very difficult. Therefore, I added vertical lines in outlook message pane to fix the issue. This action will allow you to differentiate between emails more easily. See the below screenshot where the messages are without any line separators.


Microsoft Outlook is a personal information manager product from Microsoft, available as a part of the Microsoft Office suite.

Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note taking, journal, and web browsing.
