Exchange - Repeated IDs

Hi! I'm quite new on Power BI and I just found a weird problem that I'm not really sure what is causing it.

We are interested in monitoring data from an specific e-mail account in order to know (through some rules and filters) if a task has been done correctly or not. If the task has not been completed, we want to provide the direct link to the specific e-mail from where we get the information.

The fact is, when we load data from Exchange, appears a field called "Id" (through which we get the direct link to the message), which it is supposed to be unique, but it is not:

Even though you cannot see the entire ID, some of them are the same.

Due to sometimes the ID is repeated, we obtain the same link for different messages (which of course redirect to the same message).

We attatch here some example where you can see the same ID and a different message:

We covered some information due to privacy

Does anybody knows why is this happening? Is this problem caused by Power BI or by Exchange? Any solution for this?

More details:

- We receive around 200 emails per day and almost all at the same time (between 1:00 to 9:00 am)

- If the id is repeated, is repeated only two times and usually in the same day (difference between them about 3-4 hours usually)

- Apparently there is no relation among the messages with the same Id

Thanks.
