"archive.pst cannot be opened" when archiving

[RichardS]

Error while archiving folder "Top of Personal Folders" in store "Personal
Folders". The file C:\Users\....\AppData\Local\Microsoft\Outlook\archive.pst
cannot be opened

That usually happens when the file is either oversized (around 2GB for ANSI
formatted pst-files) or when the pst-file holds errors.
