They receive a lot of PDFs, Catalogues and Pictures.
At the same time it’s really important for them to have all the emails in their inbox.

I am sorry I can not provide them this feature as it would make their day.
And I also know that solutions that do cost a lot of money.

In the end, that feature along with others remain on my wish list.
As for performance increases I don’t really agree with you as the latest Exchange releases can work really well with SATA drives but they require a lot of RAM, it’s by design. You also get similar effect by stripping big attachments and keeping emails or stripping both attachments and emails.
I think there is potential for this feature, as is for separating Datastores one for important archive and the other for less important emails, maybe one for compliance as well (journaling).

Just my 2 cents.

Hope you don’t mind me picking up on a point about the lack of ‘attachment only’ archiving…

I’m sure there are scenarios where this is useful however the view we take is that messages are such a relatively small amount of data once you’ve removed the attachment that in most cases it makes sense to store them too.

You’d also miss out on the performance increases that come from having less entries in the Exchange database as these still need to be written for the messages. We like to archive off as much as possible so Exchange sees the biggest reduction in load we can manage.

Thanks again,

James
