In 1536, Olav fled Steinvikholm Castle to Nidarholm Abbey on Munkholmen ( Norwegian, "Monk's Isle" ), a small island just outside Trondheim, and spent the winter there.

In the following spring, on 3 May 1537, Mary of Austria, the Governor of the Netherlands at that time, agreed to a truce of three years with Christian III.
 One of the paragraphs of the agreement specifically referred to Olav Engelbrektsson, allowing him the possibility of emigration to any country of his choice with his personal belongings.
If he was already in captivity, he was to be freed immediately.
But, by then, he had already been in the Habsburg Netherlands for two days.

The Archbishop had waited as long as he could to leave Norway.
 His last act as the Archbishop of Nidaros was the consecration of Sigmundur Eyjólfsson of Iceland as the Bishop of Skálholt on Palm Sunday, 25 March 1537, in the ruins of the Cathedral of Nidaros.
 A week later, on Easter Sunday, 1 April 1537, the Archbishop left Nidaros with 60 followers.
 He took the archives of the Archdiocese, including the Register paa Sancta Oluffa Ioerdher, with him.
but he left behind St. Olav's shrine and other valuables.
 However, he was saddled (possibly unfairly) with the reputation of having looted the Nidaros Cathedral.
 After his death, his archives went to the Louis V, the Elector of the Palatinate, in Heidelberg and later to the Bavarian Royal Archives in Munich but in 1830 they were returned to Norway.

On 1 May 1537, the Archbishop and his entourage arrived at Enkhuizen, a port of the Duchy of Burgundy, to a hearty welcome.
 They were assigned to Lierre (now Lier, Belgium) in the Duchy of Brabant, where he died on 6 February 1538.
He is buried under the high altar of the Church of Saint Gommaire in Lierre.
 His grave is marked by a plaque, unveiled on 21 May 2003 by Queen Sonja of Norway on her official visit to Belgium and made by a resident of Trondheim, Marit Wiklund.
