We need folder.bind similar method in Graph SDK using C#.

Below method works with Outlook Exchange services but for O365 user its not working.

var msgRootFId = new EWS.FolderId(EWS.WellKnownFolderName.MsgFolderRoot, new EWS.Mailbox(SMTPAddress)); msgRoot = EWS.Folder.Bind(service, msgRootFId, EWS.BasePropertySet.IdOnly);

    The equivalent graph SDK method would be 

     var msgRoot= .Users[SMTPAddress].MailFolders["MsgfolderRoot"].Request().GetAsync().GetAwaiter().GetResult();

    That should return the graph folder class. When you say something doesn't work you should always include any errors you receive as that will tell anybody looking at the problem what is going wrong. Eg the following would fail if you where using Delegate permission to access a Shared mailbox but didn't have the Mail.Read.Shared permissions

    var msgRootFId = new EWS.FolderId(EWS.WellKnownFolderName.MsgFolderRoot, new EWS.Mailbox(SMTPAddress));
    for this replacement is var msgRoot= .Users[SMTPAddress].MailFolders["MsgfolderRoot"].Request().GetAsync().GetAwaiter().GetResult();

    That's not correct all that line does in EWS is creates a FolderId object to be used in the next call which isn't' needed in Graph, it doesn't make any requests to EWS

    msgRoot = EWS.Folder.Bind(service, msgRootFId, EWS.BasePropertySet.IdOnly); what is method in Graph SDK?

    Folder Bind makes a GetFolder Request in EWS that returns the folder and with the property set your using it would only just return the id so 

     var msgRoot= .Users[SMTPAddress].MailFolders["MsgfolderRoot"].Request().GetAsync().GetAwaiter().GetResult();

    Does exactly the same thing in the Graph eg it make a REST get and returns the MsgFolderRoot for that mailbox, if you want to limit it to just the Id then 

    var msgRoot= .Users[SMTPAddress].MailFolders["MsgfolderRoot"].Request().Select("id")..GetAsync().GetAwaiter().GetResult();

    The Id's you get back will be different in that one is the EWSId for the Mailbox and the other is the RestId
