This behavior may occur if one of the following factors is true:
1. Excluded from AutoArchive - A specific item will not be archived when the property is set to exclude it from AutoArchive. You can find this option by opening this item and then choose File-> Properties-> option Do not AutoArchive this item.
2. Modified date or sent/received date
- By default, Archiving works based on the modified date of an item. The modified date of an item can be viewed by opening the item and then choose File-> Properties. The item will only be archived when the modified date of the item is older than the
date set for archiving. Actions that can cause the modified date to change are
reply
reply to all
forward
move to another folder
editing
saving
importing
In some cases (depending on the tools being used) scanning the item by for instance a virus scanner, anti-spam filter or synchronization software can also cause the modified date to be changed.
To change the Archive feature to function on the sent/received date of an item instead of on the modified date, you must install update:

3. Damaged archive.pst
- When the archive.pst file (or whatever the name of the pst-file is you archive to) has become corrupted it will not be possible for Outlook to archive to that file. You should then close Outlook and use the Inbox Repair Tool (scanpst.exe) to scan it for
errors or create a new one.
The location of scanpst.exe depends on the version of Outlook that you are using. You can find the location of and usage manual for scanpst.exe in the guide:

Thank you for your response.
I've already verified that "Do not Autoarchive" is NOT checked, so I don't believe that's my problem.
Also, as I've mentioned, I checked the modified dates of the items I want to archive and they all match the sent/receive date, so that doesn't appear to be the issue either.
As for scanpst, I did not check the existing archive file for damage, but I did create a brand new archive.pst to use instead and archving still fails to occur.
Any other suggestions?
