A permissions issue or a file format error, similar to the images below will be encountered when trying to open a document or file from Microsoft Word, Power Point or Excel.
This has been seen happening on multiple versions of macOS and Microsoft Office.
Typically, this is noticed when duplicate fonts are activated at the same time as fonts in your system folder. Microsoft typically installs its own fonts for use in its applications.
Please try the following steps:
- Quit all open Microsoft applications.
- Deactivate all fonts in your Connect Libraries (not the system fonts).
- Once completed, try opening the document(s) again.
Activating fonts at the same time will result in a short activation period. Please see Font will not activate or activates for a brief moment.
If the above step does not work, please try clearing your font cache. This can be a contributing factor when it has not been cleaned/cleared. In Connect, choose File > Clean Font Caches. This will purge your system font caches. Once complete, restart your Mac.
