Hello @Jacek Gulgowski
Thanks for reaching out!
Based on my research, there is no MS graph documentation which can tell upper/lower limits for Relevance score values. However, the score can be negative too.
As Relevance is determined by the user’s communication and collaboration patterns and business relationships. People can be local contacts or from an organization’s directory, and people from recent communications. So, you can compare the relevance score for the same email address in different moments in time. Higher the score, higher is the relevancy.
As mentioned previously, higher the score means more relevancy. So, abc@test .com is more relevant to User B when compared with User A.
Relevance is determined by the user’s communication and collaboration patterns and business relationships.
