              @lettoknow,
I suggest you to please try using following sample code on your end to backup account on PST.
IEWSClient client = EWSClient.GetEWSClient("https://outlook.office365.com/ews/exchange.asmx",
    email, password);
client.ReconnectCount = 3;
var folderInfoCollection = client.ListSubFolders(client.GetMailboxInfo().RootUri);
client.Backup(folderInfoCollection, path + "output.pst", BackupOptions.Recursive);
