Last year I bought an office licence through work and bought a laptop which came with a trial of office preinstalled. I tried activating the trial with my bought license but no dice. I tried uninstalling the trial, didn’t work. I ended up calling MS support and they remotes into the laptop, with my authorisation, cleaned up the trial with a special removal tool and got me up and running.

Now ok the problem was caused by them in the first place, but support was easy up contact, I didn’t wait long and they fixed the problem.

Corporations use a lot of fancy tech like Citrix, VDIs, remote application management software, securuty software, etc. They can often end up with weird problems with software compatibility and need vendor support.
