Oe stars possibly form an extension to higher temperatures of the Bephenomenon, but it is still unclear whether these stars have disks. X-rayspectra could provide hints for interactions of the star with a putativesurrounding disk. We obtained XMM-Newton observations of two Oe stars, HD45314and HD60848. Spectra and light curves were extracted and analysed. Opticalspectra were also obtained to support the X-ray observations. We find that bothstars display very different X-ray properties. Whilst HD60848 has an X-rayspectrum and emission level typical for its spectral type, HD45314 displays avery hard X-ray emission, dominated by a thermal plasma with kT ~ 21 keV.Furthermore, HD45314 displays count rate variations by a factor 2 on timescalesof ~ 1000s and a high log(L_X/L_bol) = -6.10 +/- 0.03. The X-ray properties ofHD45314 indicate that this star is a new member of the class of gamma Casanalogs, the first one among the original category of Oe stars.
