I cannot add the cloud storage (iCloud Drive (Mac), Dropbox, Google Drive) to Places in the Microsoft Office 2013 apps (Word, Excel, Access, Powerpoint).
The warning message similar to this appears:
Sorry, we're having server problems, so we can't add iCloud Drive (Mac) now. Please try again later.
Parallels Desktop Developmenat Team is aware of the issue and is now working on fixing this issue.
Restart Micrsoft Office 2013 and try to add the cloud storage again.
