If Account A shares their files with Account B and then Account A is deleted - what happens to the shared files? Can Account B still access and edit the shared files?
I have to disagree on that answer provided above. The document shared by Account A will get deleted permanently and removed from Account B within a few minutes.
Today I have tested this scenario by creating a folder in Account B and sharing it with Account A. Then using Account A I did create a new diagram in that shared folder which shared the document with Account B.
Then I deleted Account A and for approximately 5 minutes I was able to view that newly created document in Account B but eventually that diagram disappeared from Account B.
