In version 5.0.44, moving mails from one account to another the dates are updated (the mail will have date/hour given when moved)... It should mantain the original date.
You seem to have CSS turned off.
Please don't fill out this field.
This is not a bug. The faster internal date column is selected by default in the grid. You can switch the columns so it reads the date from the headers in the mail. But some mail servers sort faster on the internal date.
Tryed by switch columns... the date has changed such as in the other way...
With Outlook I can do this operation without problems.
