Are these POP or IMAP accounts?
What is the purpose of the archive?

The purpose of the archive is to reduce the size of mailbox on the Exchange server, which is approaching its maximum allowed size of 2GB. When it reaches this size it will be impossible to send or receive mails.
This is an Exchange account.

I am not sure if you are using IMAP or a restricted version of MAPI.
Make sure the server has not replicated your local archive or is linked to it in any way - you would not want it to be trashed when you eventually delete the messages from the server - perhaps keep a zipped copy elsewhere for safety.
If you are unable to find a more global 'remove deleted messages from server' in Preferences you could consider:
1 - web access to delete archived emails
2 - accessing the server with POP (at least temporarily) as POP has well understood methods of deleting from server. However:
1 - Make sure POP does not delete more than required
2 - POP only communicates with the server's Inbox so will only download or delete Inbox messages.
In the longer term you could consider moving away from Exchange mail servers.
