Microsoft office isn't working on my Mac anymore
I have tried to open Microsoft Word on my Mac for the past week and it won't let me login. My product key is also claimed to be invalid. It is already downloaded on my computer and has been for about 3 months now. It just started doing this. The error code is 0x80048823. How do I fix this? I have already tried restarting my computer. Microsoft Office is not working at all. It comes up as if I'm a new user saying enter product key, sign in to existing acct, or 30 free-trial. I try signing in and that's when it gives me an error code. I tried entering my product key to reinstall it maybe? That's when it said product key invalid. I need them to work ASAP! I am a college student and this is extremely inconvenient.
