Current setup:
1x Server 2012 R2 RDS (with activated UserProfileDisks )
1x MSI Office Professional 2016 Plus
Issue:
Can't open MS attachments in Outlook.
Word documents give me the error message saying: "Can't preview this file because it's password protected"
Excel documents give me the error message saying: "Can't preview this file because it's damaged"
Workaround:
f you have "Store all user settings and data on the user profile disk" activated then the preview pane in outlook 2013/2016 doesn't work.
If we change to the later one " Store only the following folders on the user profile disk" then the issue goes away.
But this "workaround" creates other issues, as AppData isn't saved with this setup
We can't be the only ones having this issue.
I've even tried to reinstall the Server 2012R2 with RDS without any success.
