Mac OS 26.7 and M365 Office Applications- upload block errors only on Office applications.

Thank you appreciate your response and some light at the end of the tunnel or the unexpected cliff. Sincerely appreciate the hope.

But if out of 860k only 180k are being selected to sync is this a problem i am facing with only Office applications and not PDFs or screenshots - every thing goes up but MS Word and Excel and those also go up sometimes or behave in some sporadic manner. The climb to 860K did not happen overnight and its been working till September 19th when it expressed this Upload blocked error in Word and Excel - working on till 18th with maybe a maximum of 20 file increase and then it got allergic reactions.

Lastly, how do i sign up for Insiders ring users- i am ready for ring: "OneDrive sync on macOS will increase its item limit from 300,000 to 1 million per device, starting with a Public Preview in mid-October 2026 for Insiders ring users."

The device is a M4 Max Pro with 128 gb ram and 16 cores and 2tb hard drive- i suspect my ammunition is sufficient. 

Cheers and again you are my rock star for the day! I had already set up a meeting with Box.com for this afternoon and i am excited to say in the ring of M365 with your response. 

Are there any rewards for you i can present.
