Memories, memories ... I set up and administered a Lotus Notes server in the early/mid 1990's. My main job was Finance Manager, so Lotus Notes admin was just a hobby.
A bit later, Lotus Notes was made THE standard of the multinational company and "my server" was moved to the IT department.
Contrary to most of commenters, I liked Lotus Notes, and was running it on OS/2 (more nostalgia). I never liked Microsoft or any of their products. Nowadays, as retiree, I'm in the Apple ecosystem spiced with some Linux and Raspberry Pi.
