It would be very useful if a Code Weaver representative could publish definitive instructions for installing Office 365.
Overall, considering this is a paid for emulation layer it's disappointing performance for one of the headline reasons for using crossover, I think it's time for a bit more effort to be put into stability of crossover. It would be great if all of O365 worked rather than just the basics of word and excel, even those two are prone to crashing. I first load outlook and add the email address attached to my O365 subscription, after that everything seems to work just fine, well, outlook is flaky as hell and will only work with exchange mailboxes, Word and Excel are fine, not used Access but it does load, publisher is a bit unstable so it can be frustrating to use, OneDrive doesn't work which kind of limits some of the core functions of O365. I downloaded the latest office installer from, I used the Install Windows Software button and made sure I updated the recipe and let it install all the dependencies it needed. The laptop I'm installing it on is a Dell XPS 15, Ubuntu 19.10, Linux 5.3.0-46-generic, GNOME 3.34.3, GPu1 Intel UHD Graphics 630, GPU2 NVIDIA NVIDIA Corporation Device 1f91 (on demand) CPU Intel i7-9750H (12) 4.500GHz.
