How many users can be added to a MS Dynamics 365 Team?

Question

Theoretically I'm sure there is probably no limit, but realistically I'm looking to understand how many users can be added into a MS Dynamics 365 Team. I'd like to understand what impact adding more than 8,000 users to a single team would have in terms of performance of the Dynamics application.

Why so many users in a team? We're looking at a potential requirement, which needs to secure 4 fields on an entity so that users can create those fields but not view the data in them. Short Answer: Field Level Security. However, we have a large user base ie. 8,000 users and once we create a field security profile, we need to assign that profile to 8,000 users. So an idea was to create a Team and assign the field security profile to the team. Then add 8000 users into that team.

So back to my original question. Is this a plausible solution and is there anything we're overlooking in going ahead with this. Would we face performance issues going forward? Is there a better/alternate solution to meet the requirement?

Answer 1

This 8k users + team + FLS scenario should not be a problem, as I remember from this performance benchmark (on online CRM 2016 update 1 though. ie v8.1), the testing was performed and gave better results with below configuration to prove statistically.

Field-level security was also enabled on custom attributes to reflect a realistic enterprise organization.

Based on customer research, each user of a specific role was assigned a realistic set of data. The data that the user would own was based on the user's role. Before the test, the total data in the test database included more than 656,549,587 business records with a total database size of 1.024 TB.

TeamMembership with 61,406 records.

A batch of 17,868 concurrent users performed create, update, and delete (CRUD) operations within Dynamics CRM Online.
