mac os x outlook changekey is required for this operation

I tried a few quick rm filename -r and rmdir filename commands to no avail.

However, this fix didnt work for the Volumes folder, just every other folder.

Tried: - PRAMSMB reset also no effect.

Delete commands in terminal also in recovery mode - no effect.

The solution: - Backup to time machine exclude that particular files parent dir.

Reboot in recovery, using disk utility, erase the problem drive completely, - Restore from Time machine.

However, upon later inspection, I realized I was using the command rm drivename -r, instead of rm -r drivename.

No need to force quit and after relaunching, things were normal.

Although I have occasionally encountered strange Finder issues that required a reboot for the situation to resolve.) At least when I encountered this bizarre behavior (on my start-up drive, with documents in my Downloads directory, quitting and re-launching the Finder app did, indeed, resolve the situation.

But the answer could be improved to just right-click Finder and hit relaunch.

I opened Activity Monitor, selected Finder in the list, and chose Force Quit.

When I clicked Finder again in the Dock to start it anew, I could delete files.

Then open your Trash, select all the item ( Cmd A ), drag everything to the Terminal window, then press Return.
