We present a 154 pointing IRAM NOEMA mosaic of the CO(1-0) line emission inand around the nearby starburst galaxy M82. The observations, complemented byzero--spacing observations, reach a spatial resolution of $\sim$30 pc ($\sim1.9^{\prime\prime}$) at 5.0 km s$^{-1}$ spectral resolution, sufficient toresolve the molecular gas in the central starburst disk, the outflow, as wellas the tidal streamers. The resulting moment and peak brightness maps show astriking amount of structure. Using a clump decomposition algorithm, we analysethe physical properties (e.g., radii $R$, line widths $\sigma$, and masses $M$)of $\sim2000$ molecular clouds. To first order, the clouds' properties are verysimilar, irrespective of their environment. This also holds for the size-linewidth relations of the clouds. The distribution of clouds in the $\sigma^2/R$vs. column density $\Sigma$ space suggests that external pressure does not playa significant role in setting their physical parameters in the outflow and thestreamers. We find that the clouds in the streamers stay approximately constantin size ($R \sim 50$ pc) and mass ($M \sim 10^5$ M$_\odot$) and do not varywith their projected distance from M82's center. The clouds in the outflow, onthe other hand, appear to decrease in size and mass with distance towards theSouthern outflow. The reduction in the molecular gas luminosity could beindicative of cloud evaporation of embedded clouds in the hot outflow.
