I'm trying to archive emails in Outlook 2007. I set up Auto archive to archive anything older then X amount of months but it didn't archive anything. After a little Googling I discovered that the date that counts is the Modified date, not the Sent or Received dates. I reset the amount of months taking into account the modified date of the emails but it still isn't being archived.
What other setting/issues do I need to check for?
I had this problem, and the solution in my case was that the default Autoarchive setting MUST be turned on:
Outlook > Tools > Options > Other > Autoarchive
[x] Run Autoarchive every [n] days
[x] Archive or delete old items
Set a high value (e.g. 99 Months), and a well-known destination PST to reduce the chance that Outlook may move items unexpectedly. Then Outlook will process/respect your individual folders' Autoarchive settings.
This is a change from Outlook 2003, where the global option was not necessary and Outlook would still autoarchive based on individual folders' settings.
There is an article about this issue and it suggests checking the following:
