Exchange Online Mailbox Plans are templates used to define the default settings, such as storage quotas and feature sets, for new mailboxes. These plans ensure consistency across the organization by automatically applying the correct configurations based on the assigned license.
"While most admins use default plans, knowing that these govern the size and capabilities of the mailbox is key for capacity planning."

🎯 How does Exchange Online Mailbox Plans appear on the MS-102 Exam?
You may be asked to identify the mechanism that automatically assigns a 50GB or 100GB storage limit to a user based on their assigned Microsoft 365 license.
A scenario might describe a user who can receive but not send emails due to storage limits; you will need to relate this to the 'Prohibit Send' quota in the mailbox plan.
Expect questions where you must determine how to ensure all new users in a specific department receive identical mailbox settings and feature sets upon provisioning.
❓ Frequently Asked Questions
What is the difference between a Microsoft 365 license and a mailbox plan?
A license is the legal entitlement that grants a user access to the service, whereas the mailbox plan is the technical template that defines the actual storage limits and features provided by that license.
Can I manually override a mailbox plan for a single user?
While plans provide the default template at creation, administrators can manually modify the storage quotas for individual mailboxes using the Exchange Admin Center or PowerShell to meet specific user needs.
