Outlook 2010 not archiving subfolders

[tshaff09]

I'm running up againt this issue with subfolders of my inbox. Does "modified" date also include synchronize date on sub-folders? That's the only thing I can see being the issue in my case. I have a folder with old emails that are not touched, but synchronizing happens. Emails from the inbox archive fine, and the subfolder is created in the archive.pst, but none of the subfolder contents are archived.

If you right click on the folder in question->Properties->AutoArchive -> is it set to Archive or NOT to archive?

Thanks Steve.
Yes. Auto archive is on for the folder and its contents... very bizarre

My archives setting are looking at all mail older then 3 months...and it uses the received date..

Do you have mail in the folders in question older then your settings?

The emails in the subfolder are a couple years old, and not modified at all.
It's bizarre. Wondering if there is some exchange setting causing this? Another user had similar - folder structure was cretated in archive pst, but emails not moved in.
