How to View Gmail Messages in Reverse Chronological Order
When you sort messages by date in Gmail, you see the last page of messages first, but the messages are still listed from newest to oldest. If a folder has only one page of messages, look at the bottom of the screen to see the oldest conversation. If a folder has multiple pages of messages, use this workaround:
In the upper-right corner, just above your messages, there’s a number that shows how many emails are in the current folder. Hover the mouse over the email counter until a small menu drops down and choose Oldest. You’re taken to the last page of emails in that folder; the oldest message is listed at the bottom. To move back to a previous screen to see newer messages, use the back arrow next to the email count. If you want to read your Gmail messages in the default order, select the email counter and choose Newest from the drop-down menu.
