Extending previous work by Meise and Vogt, we characterize those convolution operators, defined on the space $𝓔_{(ω)}(ℝ)$ of (ω)-quasianalytic functions of Beurling type of one variable, which admit a continuous linear right inverse. Also, we characterize those (ω)-ultradifferential operators which admit a continuous linear right inverse on $𝓔_{(ω)} [a, b]$ for each compact interval [a,b] and we show that this property is in fact weaker than the existence of a continuous linear right inverse on $𝓔_{(ω)}(ℝ)$.
