I have an older iMac (27 inch late 2015), with a 3.2 quad-core Intel i5 with 8 Gb memory, running macOS Monterey Version 12.7.6.- the system tells me that this is up-to-date
However, my Microsoft auto-update notice indicates that I need to upgrade to MacOS 13.0 or later for Excel, One Note, Outlook, PowerPoint and Word.
I appreciate any advice on what needs to occur.

iMac 27″, macOS 12.7
macOS 12 Monterey is the highest that a Late 2015 27" iMac can run.
If you need to run a later macOS version, then you need a newer or new Mac.

To use any app that requires macOS 13, 14 or 15 you will need a newer computer.
Microsoft Support – Upgrade macOS to continue receiving Microsoft 365 and Office for Mac updates
"If you’re on an unsupported version of macOS, your Office apps will still work but you would no longer receive any updates including security updates. For example, if you’re on macOS Monterey, but later you don’t update your macOS to a supported version when macOS Monterey is no longer supported, you won’t receive any updates of any kind."
Note that Monterey is good enough to run current versions of LibreOffice – which I believe will run even on Catalina.
Also, please consider replacing your 2015 Mac. It is now obsolete and considered vintage. The problem you are experiencing is just the first software incompatibility issue you are experiencing. Unfortunately the longer you continue to use the computer the more software issues you will begin experiencing.
Disable auto-updates, they are n/a to your Mac.
How can I update my iMac to allow Microsoft Upgrades?
