Recently, a few of our older Lenovo All-in-One workstations have been struggling to connect to Office 365 resources. This issue seemed to pop up right after a recent update, and I didn't see any login attempts in the sign-in logs, making me suspect the problem might be local. So far, the only solution we've found is to reimage these machines, which is quite time-consuming for our team since we have a lot of these workstations used by accountants and receptionists. Has anyone else encountered similar issues? If so, what solutions worked for you?

I found a thread about this on Reddit, and surprisingly, one of the comments actually worked for me. It might be worth checking out. Here's the link: https://www.reddit.com/r/Office365/comments/wsbf7f/comment/mzmbdgd
You might want to check the proxy settings in Internet Explorer. Try toggling the "automatically detect" proxy checkbox in the LAN settings and reboot your machines. This small change helped some users I know.
It sounds like you could try the online repair option. Office has a method that removes the key assigned to the user account, and it could fix this without needing a full reimage. Give that a shot and see how it goes!
Resetting Internet Explorer to its default settings can solve a lot of these types of issues, especially when users can't authenticate with Outlook or Teams. I run this command frequently: RunDll32.exe InetCpl.cpl,ResetIEtoDefaults. It doesn't delete personal settings either, so it's pretty safe to do.
Thanks for the suggestion! But I actually tried that repair option, and it didn’t help. The only thing that's worked is reimaging, unfortunately.
