Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I am having the very same problem. It is the most frustrating thing. My IT people have had absolutely no luck in finding the solution to this problem. They've even spoken with the people at Microsoft Office and they were told to re-install my Office program. This in itself was a nightmare because I lost all of my personal settings and had to start all over again. But even after all that, it STILL didn't fix the problem. But what's worse is that now I'm getting another error message in addition to the out of memory message. The new message is "Sorry, something went wrong and Word was unable to start. (24)"
So, I too am looking for ANY help in getting this problem resolved.
