Messages returned by Microsoft Graph API have nil properties.

Question

We have been experiencing an odd issue for some of our accounts, and are looking for some assistance.

When scanning a folder for new messages (ie. the request looking like: /mailFolders/#{``folder_id`` }/messages/delta)

we get as a response a list of messages that sometimes do not have any properties (specifically createdDateTime, lastModifiedDateTime, isDraft, isRead, receivedDateTime are empty and the length of the subject and the email body are 0). We are also not able to retrieve the immutable ID through the translateExchangeIds function.

We are wondering why that could happen and how to troubleshoot further.

Thanks,
