We investigate the properties an exotic symbol class of pseudodifferential operators, Sjostrand's class, with methods of time-frequency analysis (phase space analysis). Compared to the classical treatment, the time-frequency approach leads to striklingly simple proofs of Sjostrand's fundamental results and to far-reaching generalizations
