Hi everyone,

Is there any user limit in Microsoft 365 Exchange Online (plan1/plan2)? In case of other license plans I found those information easily for example M365 Business Basic/Standard/Premium has 300 users limit, and O365 Enterprise E1 up to E5 has no limitation. But in case of Exchange Online I can't find anything. In links below are a tons of very detailed information but nothing about what I'm looking for.

Microsoft Exchange Online: A Microsoft email and calendaring hosted service.Management: The act or process of organizing, handling, directing or controlling something.
