This message is associated with Microsoft 365 Roadmap ID 70751.
When this will happen
We will begin rolling this out in mid-March 2021and expect to complete rollout by late April 2021.
How this will affect your organization
When you type in the people picker, the autofill suggestions will come from Microsoft Graph. This makes it the people picker more personalized and relevant based on who you work with most often.
