MsGraph - problem with downloading messages with attachments from the mailbox

Jaromin, Marcin 0 Reputation points

I have a question related to MsGraph result and I hope, you can help us.

We have one problem with downloading messages with attachments from the mailbox.

In this case, we have a mail file inside the email (as an attachment), instead of the correct eml file we have *.bin or *.dat binary file.


Do you have any idea how we can manage it?

I mean, get it without encryption

    Hello Jaromin Marcin,
    Thank you for reaching out.
    Could you please share the API you are using to download message with attachment?

    Is the email you are trying to download encrypted ?

    Please share us details information.
