For Exchange 2019, it recommends 128GB RAM?

I will have roughly 200 mailboxes on a Hyper-V VM. How much RAM will I actually need?

I am currently running Exchange 2016 that is using about 15GB RAM.

For Skype 2019, what non-subscription alternatives are there for voicemail as Exchange 2019 will not have unified messaging?

For Skype 2019, how high is CPU usage as far as needing 8 cores? My current processor has 4 cores. This too will be in a Hyper-V VM running with a Skype Edge VM.

How much RAM does Skype 2019 actually use? There probably won't be too many user on at one time.

Thanks

    Hi @Susan Dodds ,

    In fact, Exchange Server storage sizing includes the Exchange Server storage sizing includes estimating the storage space to accommodate databases, content indexes, transaction logs, growth factors, and unexpected overhead growth, so we have no accurate way to calculate it. As a workaround, you can try to use the following link’s calculator to calculate it:
