MS Exchange integration

I'm looking at the Exchange integration to replace what what we developed locally. We are gathering more logs than the new integration gathers, but I'm not an Exchange SME, so I don't know what the SME's will miss.

Logs we gathered by aren't by the new integration:

  1. Hub connectivity
  2. Frontend smtpsend
  3. Hub smtpreceive

We didn't gather httpproxy, it will be new. We don't gather pop/imap, but they say we don't use it.

Has anyone looked at these other logs? Thanks
