Rt Revd Michael Perham was told by police last month he will face no action after being questioned about two claims of indecent assault.
He's due to retire officially on 21 November but has not been involved in any duties since the allegations were made.
The Bishop of Tewkesbury has taken over the running of the diocese and said the cancellation was sad: "I know this will be the cause of huge frustration and deep disappointment."
Rt Rev Martyn Snow added: "Church House, Westminster has confirmed to me the process is still ongoing and there is a formal timetable for this process as it must be completed with fairness to all.
"The diocese must therefore await the conclusion of that process."
Bishop Michael has always denied the allegations of historical sex offences made in August.
