At opening document in MS Project app I see message: "Project cannot recognize this file format. Do you want to open this file as text only?". It's very strange, because only yesterday file was valid. Obviously I need something like microsoft project recovery tool or effective guide.
hi Elsie, It would be hard to answer the question as MS project app is not a Koodo product and/or a Koodo devices. What I would try is to open the file in a laptop/destop and see if you can open it there.
