Question

I have the following functions to get messages using Graph API

var client = new GraphServiceClient(authenticationProvider);
var messages = await client.Users["useer@domain.com"].Messages
     .Request()
     .GetAsync();

Answer 1

Found the answer after googling and trial error.

IUserMessagesCollectionPage msgs = await _client.Users[user@domain.com].Messages.Request()
                .Filter("put your filter here")
                .GetAsync();
            List<Message> messages = new List<Message>();
            messages.AddRange(msgs.CurrentPage);
            while (msgs.NextPageRequest != null)
            {
                await msgs.NextPageRequest.GetAsync();
                messages.AddRange(msgs.CurrentPage);
            }

I think you should refer to this document :

Depending on the page size and mailbox data, getting messages from a mailbox can incur multiple requests. The default page size is 10 messages. To get the next page of messages, simply apply the entire URL returned in @odata.nextLink to the next get-messages request. This URL includes any query parameters you may have specified in the initial request.

You can do it with .Top():

var client = new GraphServiceClient(authenticationProvider);
var messages = await client.Users["user@domain.com"].Messages
     .Request()
     .Top(100)
     .GetAsync();
