The answer is that the user’s mailbox is still on-premises and not migrated to Exchange Online. This is the most likely cause because Microsoft Teams relies entirely on Exchange Online for scheduling functionality, including private meeting creation; even when the Teams meeting policy “Allow private meeting scheduling” is set to ‘On’, the Teams desktop client cannot communicate with an on-premises Exchange server to process the meeting request, so the “Meeting creation is disabled by your IT administrator” error persists. On the Microsoft 365 Administrator MS-102 exam, this scenario tests your understanding of the dependency between Teams and Exchange Online, often appearing as a trap where candidates focus only on Teams admin center policies while overlooking the mailbox location. A common memory tip is “Teams talks to Exchange Online, not on-premises—if the mailbox is on-prem, meetings are gone.”
MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are a Microsoft 365 administrator. Users report that they cannot create Microsoft Teams meetings using the Teams desktop client. They receive an error: 'Meeting creation is disabled by your IT administrator.' You need to enable meeting creation. You check the Teams admin center and find that meeting policies are set to 'Off' for 'Allow private meeting scheduling'. However, after changing it to 'On', users still get the error. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: OAuth is used for authentication but not directly related to the policy enforcement.
B
The global meeting policy is overriding the user-level policy.
Why wrong: The error indicates the policy is disabled; changing the user policy should work unless overridden, but the error persists, suggesting a deeper issue.
C
The user's mailbox is still on-premises and not migrated to Exchange Online.
Teams meeting scheduling relies on Exchange Online mailbox; if mailbox is on-premises, the Teams policy cannot be enforced.
D
The user does not have a Microsoft Teams license assigned.
Why wrong: License is required for Teams, but meeting creation policy is separate.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user's mailbox is still on-premises and not migrated to Exchange Online.
The error persists because the user's mailbox is still on-premises and not migrated to Exchange Online. Microsoft Teams relies on Exchange Online for scheduling features, including private meeting creation. Even with the meeting policy set to 'On', if the mailbox is on-premises, the Teams client cannot communicate with Exchange Online to create the meeting, resulting in the error.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume changing the meeting policy in the Teams admin center is sufficient, overlooking the critical dependency on Exchange Online for Teams calendar features, which is a common misconfiguration in hybrid environments.
Detailed technical explanation
How to think about this question
Teams meeting creation requires the user's mailbox to be hosted in Exchange Online because the Teams client uses Exchange Web Services (EWS) or REST APIs to create calendar items. When the mailbox is on-premises, these APIs are not available, and Teams falls back to a limited functionality mode. This is a common scenario in hybrid deployments where mailbox migration is incomplete, and it highlights the dependency between Teams and Exchange Online for scheduling features.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
