How to get all messages in Outlook using Microsoft Graph API?

Question

2

I have a question about Microsoft Graph API for C# code. Is it possible to get all messages which I have in Outlook?

I found a good article, but I'm still not getting an answer to my question. The article: https://stackoverflow.com/questions/64455925/get-all-email-message-using-microsoft-graph-api-in-c-sharp

I found a good video about how to connect to Microsoft Graph: https://www.youtube.com/watch?v=acnFrkBL1kE&ab_channel=Microsoft365Developer

I have still the same question. I can get 1000 emails for call. Is there any way to get all messages from my Outlook? They should be from all my folders.

My new code for call 1000 messages:

public async Task<(IEnumerable<Message> Messages, string NextLink)> GetUserMessagesPage(  
        string nextPageLink = null, int top = 1000)  
    {  
        IUserMessagesCollectionPage pagedMessages;  
  
        if(nextPageLink == null)  
        {  
                pagedMessages = await _graphServiceClient.Me.Messages.Request().Select(msg => new  
                {  
                    msg.Subject,  
                    msg.BodyPreview,  
                    msg.ReceivedDateTime  
                }).OrderBy("receivedDateTime desc").Top(1000).GetAsync();  
        }  
        else  
        {  
            var messagesCollectionRequest = new UserMessagesCollectionRequest(nextPageLink, _graphServiceClient, null);  
            pagedMessages = await messagesCollectionRequest.GetAsync();  
        }  
        return (Messages: pagedMessages, NextLink: GetNextLink(pagedMessages));  
    }
