The event was due to be held in Cannes in the south of France from March 10-13.
It has now been rescheduled for June 2-5.
Paul Zilk, chief executive of organiser Reed MIDEM said: “The well-being of our clients and staff is our priority. Given the evolving context, the best course of action is to postpone MIPIM to June.
“This is not a decision we have taken lightly. We believe these new dates will provide the international MIPIM community with the opportunity to achieve their business objectives.
“We are grateful to our clients for their support and constructive input during this challenging period, and we look forward to talking with them in the coming days about MIPIM in June.”
The move follows a series of drop-outs from big name property firms and a ban by the French government on all indoor gatherings of more than 5,000 people.
