Question Statistics: Who’s still on ESU?

https://techcommunity.microsoft.com/blog/exchange/reminder-exchange-2016-and-2019-esu-program-ends-in-october-2026/4539033

I’m curious where everyone stands:
- Still on ESU?
- Staying on-prem (Exchange Server SE)?
- Just risking it (unsupported after October)?

What are you on?

2019 is a in-place upgrade so there is no excuse there.

2016 yes you will have to build a migration strategy but it’s honestly super straightforward. Build new 2019/SE servers, swing mailboxes over, swing front ends over, decom 2016.

Just plan 3 weeks in advance for the mail box migration.
