Changing Archive to sent/received date
To change the Archive feature to function on the sent/received date of an item instead of on the modified date, you must have the following updates installed;
- Outlook 2007
Version 12.0.6550.5003 (January 2011) or later. - Outlook 2010
Version 14.0.5138.5000 (April 2011) or later (like Service Pack 1) - Outlook 2013 / 2016 / 2019 / Microsoft 365
No update needed.
When you meet the minimal requirements, you can enable the option via the Registry;
Key for Outlook 2007:HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Preferences
Key for Outlook 2010:HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences
Key for Outlook 2013:HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences
Key for Outlook 2016, Outlook 2019 and Microsoft 365HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences
Value name: ArchiveIgnoreLastModifiedTime
Value type: REG_DWORD

E-mail messages will now be archived based on their Received date, Calendar items based on their scheduled date and Task items based on their Completed date. For more information about the new and old behavior for archiving see; How to change the criteria that Outlook 2010 and Outlook 2013 use to archive different item types.
Via a Registry edit you can archive based on the Received date instead of the Modified date.
