Sorting Messages

You can sort the message list by any of the column headings, including the Read/Unread column. When you click on a column heading, your messages are sorted by that factor first in ascending order. Click again and the messages are sorted by that factor in descending order.
Note: The default sort factor is arrival time (Received) and date is always the secondary sort factor. Although these two sort factors are similar, arrival time reflects different system time zone settings. It also reflects the time in which a message first appears in a message list. For example, if you move a message from one folder to another, the moved message will have a more recent arrival time compared to all the other messages in the target folder—even if the message was originally received before the others messages in the target folder.

Once you do a sort, the Up arrow (ascending order) or Down arrow (descending order) appear.

The sort options are as follows:

To sort messages:

Click on the column heading of the column you want to sort.
The messages are sorted in ascending order by that sort option first, followed by arrival time and then date. Also, a sort icon appears next to the column heading.

Click again to reverse the sort order.
