Does the Microsoft Graph .NET client library (Microsoft Graph API) support filtering messages by body content and creation date?

[HorbachAnton]

I am using this library in my project to retrieve emails from my mailbox. However, when I try to filter messages from my mailbox by createdDateTime I get a "Bad Request" error. Here is my request:

private static IMailFolderMessagesCollectionPage GetMessages(string subject, int count) { return new graphServiceClient.Me.MailFolders.Inbox.Messages.Request().Filter($"subject eq '{subject}' and createdDateTime gt '{DateTime.Now.AddMinutes(-10)}'").Top(count).GetAsync().Result; }

Also, when I try to retrieve an email by its subject and body content - I can't get any message. Here is my request:

private static IMailFolderMessagesCollectionPage GetMessages(string subject, string bodyPart, int count) { return new graphServiceClient.Me.MailFolders.Inbox.Messages.Request().Filter($"subject eq '{subject}' and contains(body/content, '{bodyPart}')").Top(count).GetAsync().Result; }

Do the Microsoft Graph API and the library itself support filtering of emails(messages) by createdDateTime and body content?

Hey @HorbachAnton,
Thanks for raising this issue.

The filter operation is actually done on the API side and not really a function of the client library.

Any chance you have first tried constructing the desired query on Graph Explorer to confirm if you get similar results?

[HorbachAnton]

I've constructed the desired query on Graph Explorer and got the similar results. There are no messages in reply. My query.

https://graph.microsoft.com/v1.0/me/mailFolders('Inbox')/messages?$filter=subject eq '*****' and contains(body/content, '****')&$top=10

Do I understand correctly that a construct like 'contains(body/content, '****')' verifies that the body contains the object I specified? And the whole body of the object shouldn't just consist of it?

Hey @HorbachAnton,

As this functionality is not part of the client library, I have forwarded your question at the link below, so that the relevant API owners can help us understand if this is indeed expected behavior.

I will close this issue for now so that we may continue to follow this up from there.
