Maximum Number of Mail Contacts can we create in a Exchange online
I would like to inquire about the supported limit for creating Mail Contacts in an Exchange Online environment under a Microsoft 365 tenant licensed with the Business Basic plan.
Specifically, we need to know:
- What is the maximum number of Mail Contact objects that can be created in the tenant?
2. Are there any technical or service limitations tied to the Business Basic plan regarding Mail Contact creation?
3. Would creating a large number (e.g., 5,000 to 10,000) of Mail Contacts have any impact on tenant performance or directory synchronization?
4. Do these limits vary based on tenant type, region, or licensing tier?

I don't believe there is a maximum number of contacts that Microsoft publish
