    If you need to use the same table name you can use an extension method:

    public static class StorageExtensions
    {
        public static bool SafeCreateIfNotExists(this CloudTable table, TableRequestOptions requestOptions = null, OperationContext operationContext = null)
        {
            do
            {
                try
                {
                    return table.CreateIfNotExists(requestOptions, operationContext);
                }
                catch (StorageException e)
                {
                    if ((e.RequestInformation.HttpStatusCode == 409) && (e.RequestInformation.ExtendedErrorInformation.ErrorCode.Equals(TableErrorCodeStrings.TableBeingDeleted)))
                        Thread.Sleep(1000);// The table is currently being deleted. Try again until it works.
                    else
                        throw;
                }
            } while (true);
        }
    }
    

    WARNING! Be careful when you use this approach, because it blocks the thread. And it can go to the dead loop if third-party service (Azure) keeps generating these errors. The reason for this could be table locking, subscription expiration, service unavailability, etc.
