I am seeing this same problem. I have bought crossover because it does seem solid with Office 2007 - yes I am still using that version! However, I have been looking to upgrade to Office 2016 and ideally running under Linux and avoiding having to fire up a Windows VM. However, I have had very little luck so far.
My installation: Linux Mint 18.3 MATE Edition (all up-to-date).
Installed into default script Office 2016 bottle using the ODT and making sure that all the linux libraries suggested in "Tips and Trick" were installed. Performance Enhanced Graphics selected and finally IE8 was installed.
Two main problems:
- cannot sign in to Office 365 account as the password window is always blank.
- when running Word in trial mode, all documents are reported as corrupt.
Also seems to be unstable and regularly locks up the X Server requiring a reset. Indeed, the last crash (with PowerPoint) was so bad that it took an fsck and a Raid resync before normal service was restored. I don't really want to try again.
My experience is that Office 2016 does not work with crossover linux. Maybe the problem is installation, in which case there is really a need to get the standard installation script working.
