Which of the following are editions of Microsoft Exchange Server?

Microsoft Exchange Server has two primary editions: Standard and Enterprise. The Standard edition is designed for smaller organizations or those with fewer requirements, while the Enterprise edition offers more extensive features, capacity, and scalability options suitable for larger organizations with more demanding needs.

The Standard edition supports fewer mailbox databases and has limitations on overall storage capacity, whereas the Enterprise edition can support a larger number of databases and allows for more extensive infrastructure, which is crucial for enterprises handling a high volume of emails and user needs. This distinction between the editions allows organizations to select an appropriate version based on their specific operational requirements and growth potential.

The other options—Basic and Premium, Home and Professional, and Lite and Full—do not represent actual editions of Microsoft Exchange Server, and therefore, they are not relevant to the question being asked.
