Ex2016: Size of Mails older than n years over all Mailboxes

Copper Contributor

our Exchange 2016 databases are approximately 2.5TB.

Does anyone know how to generate a Size list of all mails by year over all Mailboxes?
Like this:


Year MailCount Mailsize in MB


Based on this data, we could consider moving all mails older than n years to a separate archive system. With this data, I would then have an argument for buying this software.


There is a blog post here for Exchange 2010.
Unfortunately, the customisation for Exchange 2016 is beyond my skill set



Maybe someone has a tip for me.

Best regards
