OneDrive Stopped Working on Mac OS Ventura

I have 365 for Mac and I access OneDrive all day everyday via the App.

I have a 2017 iMac which has Ventura OS which is the latest I can update to.

OneDrive suddenly stopped working and I understand from other threads here that Microsoft have stopped supporting OneDrive on older Mac OS such as Ventura.

I understand from another thread that moving the 'broken' OneDrive application to Trash and downloading an 'older'? version of OneDrive will get me back up and running.

My question is, if Microsoft have stopped supporting OneDrive on my Mac and if I download an older version of OneDrive, will my files and data still be secure?

    Hi @SJan555

    Thank you for reaching out. 

    Regarding your concern, yes, your files and data in OneDrive remain fully secure. As far as I know, all files stored in OneDrive are protected by Microsoft’s server-side encryption and security measures. Using an older version of the desktop app does not affect the security of your cloud files. 

    However, please note that an older OneDrive app version will not receive future security updates or bug fixes. This means the app itself carries some additional risk over time compared to running the latest supported version on a newer macOS. 

    I recommend backing up your local OneDrive folder first as a precaution before making any changes. For the best long-term experience, I suggest using OneDrive through web browser, which is fully supported and secure. You can also access your files from other devices such as your phone or a newer computer. 

    I hope this helps. 

    Please feel free to correct me if I misunderstood your request. If you have any additional concerns, feel free to comment below. I would be more than happy to assist.
