I use Axigen 10.3.1.5
How can I look and sort the writing inside the user’s mailbox by date.
I need to find the date of the oldest mail.
And I want to do it from the admin panel
If I understand your question correctly.
You are asking how to sort emails by date on webmail? Oldest to Newest or Vice versa.
The option is located on your status bar, its the same bar where you can see your details of your total number of emails.
This cannot be done on Admin panel as I know.
