Whether the 8.5 Domino Server supports the lower version Lotus Notes like 6.5.x\7.0.x\8.0.x …?
Subject: Compatibility…
Sorry wrong response
Subject: yes!
Yes! Note that newer features in the Notes server may not function in the older clients. For this reason, a user with a Notes 7 client should have the Notes 7 mail template rather than the Notes 8.5 mail template.
Subject: Yes
