This article will explain how to flag an Infoitem in 123-mail webmail. Flagging items allows you to categorize them on an arbitrary manner, rather than by any of the other values present. You can decide which colour flag represents what, and then use the flags to mark up your items. For example, you could use one colour flag to mark all of your work related items, and another colour to mark your personal items.
Login to the 123-mail webmail.
Click on the InfoStore icon on the main toolbar.
Click on the Flags tab.
Select the relevant item and then click on the Flag you wish to assign to it. You can use the Shift or Control button on your keyboard to select multiple items, allowing you to assign them a flag in bulk.
The Infoitem will now be flagged. You can click on the area of the header bag above the flag icons to order your items by flag colour.
