Exchange Bugs and Queries

Question

Query::Can we retrieve the Exchange identity, name, or ID property using the Graph API? In mailbox permissions, it seems to be using the identity for different users.

BUGS:
In the Full Access permission in Exchange: adding a group with the same name causes an error while deleting

In "Send As" permissions, and after deleting a user, it stores the security identifier.

Answer 1

The Graph API does not expose any mailbox details currently, although you can use it to fetch the details of the corresponding user. As for the issue on the screenshots, this is easily avoidable if you use unique identifiers for your objects, and part of the reason why Microsoft introduced the changes detailed in this article: https://techcommunity.microsoft.com/t5/exchange-team-blog/change-in-naming-convention-of-user-s-name-parameter/ba-p/3284733

Looks like the devs failed to follow the best practices when implementing that one in the portal...
