Is it worth migrating from on-prem Exchange to Microsoft 365 right now?

by cntentertainment337 . Updated 7 months ago

Hi everyone,

Our small company (around 80 employees) is still running on an on-premises Exchange 2016 server. It’s been stable, but managing updates, security patches, and storage is getting more of a headache every year.

I’ve been considering migrating everything to Microsoft 365, but I’m a bit unsure if it’s the right move right now. Some concerns I have:

Cost: Subscriptions for 80 users add up quickly compared to our current setup.

Downtime during migration: We can’t afford major disruption since email is mission-critical for us.

Data security and compliance: A few clients require certain data residency rules — not sure if Microsoft 365 can guarantee this for us.

For those of you who’ve already made the jump from Exchange on-prem to Microsoft 365, how smooth was the transition? Was it worth it in terms of reduced admin workload and reliability?

Would love to hear real-world experiences before I pitch this to leadership.
