  We present the time-resolved spectral analysis of the XMM-Newton data of NGC
1365, collected during one XMM-Newton observation, which caught this
"changing-look" AGN in a high flux state characterized also by a low column
density ($N_{\mathrm{H}}\sim 10^{22}$ cm $^{-2}$) of the X-ray absorber. During
this observation the low energy photoelectric cut-off is at about $\sim 1$ keV
and the primary continuum can be investigated with the XMM-Newton-RGS data,
which show strong spectral variability that can be explained as a variable low
$N_{\mathrm{H}}$, which decreased from $N_{\mathrm{H}} \sim10^{23}$ cm $^{-2}$
to $10^{22}$ cm $^{-2}$ in a 100 ks time-scale. The spectral analysis of the
last segment of the observation revealed the presence of several absorption
features that can be associated with an ionized (log $\xi \sim 2$ erg cm
s$^{-1}$) outflowing wind ($v_{\mathrm{out}} \sim 2000$ km s$^{-1}$). We
detected for the first time a possible P-Cygni profile of the Mg\,\textsc{xii}
Ly$\alpha$ line associated with this mildly ionized absorber indicative of a
wide angle outflowing wind. We suggest that this wind is a low ionization zone
of the highly ionized wind present in NGC 1365, which is responsible for the
iron K absorption lines and is located within the variable X-ray absorber. At
the end of the observation, we detected a strong absorption line at $E\sim
0.76$ keV most likely associated with a lower ionization zone of the absorber
(log $\xi \sim 0.2$ erg cm s$^{-1}$, $N_{\mathrm{H}} \sim 10^{22}$ cm $^{-2}$),
which suggests that the variable absorber in NGC 1365 could be a low ionization
zone of the disk wind.
