AD/ADSI housekeeping due to Exchange/Office365 migration

My employer recently migrated from Exchange 2003 to Office365/hosted "cloud" Exchange.  We're an SMB, single forest/single domain.  My supervisor, the VP of Operations, knows enough about IT to be dangerous, as he tends to jump in head-first, and then I have to clean up the mess.

So, here's the story...this migration was done over a weekend, and from what I can ascertain, while they removed the server from the domain (AD, Server 2003 functional level), Exchange was NOT properly uninstalled before doing so.  Further complicating the mess, this machine was then completely re-formatted and re-purposed.

Now, everything email-wise is cloud-based; there are no systems here doing anything related to email-no SMTP, no relays, etc.  However, I have a lot of Exchange-related objects left behind, such as:

MS Exchange System Objects folder in ADUC
Exchange Enterprise Servers Security Group-Domain Local
Many entries referring to Exchange in ADSI (Schema:  CN=ms-exch-????)

Can I simply delete all entries and objects that specifically refer to Exchange and/or this particular machine?

Also, a minor issue:  I have several auto-created users (IUSR and IWAM) in ADUC that refer to this Exchange system and a few other non-existent systems; can I safely delete them?

Many thanks in advance!

If you no longer have Exchange in your environment, it is safe to remove the legacy items that Exchange once used. This also includes any Exchange Server (computer objects) as well.

Use the article below to remove legacy Exchange items from Active Directory. This also includes ADSIEdit.msc method.
