Outlook: a GUI to manage PST content

[Skysnake]

This assumes implementation of the OutlookEX UDF.

I have PSTs which are becoming unmanageable 

The idea is to make a simple GUI (Listview) which can combine non-Outlook data and include emails based on criteria.  Manage them in the GUI (delete / reply etc) and update to Outlook.

So the issue would be to manage the items in the GUI while using the PST as a database.

Ideas on how to do this? What would the key be?

Each item is identified by a key property named EntryID: https://docs.microsoft.com/de-de/office/vba/api/outlook.mailitem.entryid
