I recently installed the Samsung OneUI 7 update on my S23 Ultra. Everything else seems to be working fine, but if I attempt to open Word or Excel, they simply refuse to open. The animation of the button opening up starts and then it collapses back down again.

I tried clearing the cache on Word and it had no effect. Then I tried to restarting my phone. It had no effect. Next I tried uninstalling and reinstalling it. No effect.

Outlook and Family Safety still work. But Word, Excel, and OneNote all don't.

I fixed it. When I opened the Office Mobile app, it had a storage/access request prompt. After I dealt with that, I opened Word and Excel from that app.

Based on the app details, it appears that this Office Mobile app came from the Samsung Cloud store and might be a pre-installed app. I'm not sure if it's actually good for anything or if it's just an advertisement for Word, Excel, and PowerPoint. Either way, it seems to be the source of the issues I was experiencing.

    This is it. I stumbled upon this when looking at permissions. Scrolling though apps that had file access permissions, I saw Microsoft office in the list, despite it having been deleted. But this had a little blue lock icon on it. So I went into the secure folder, and apps list in settings, and there it was hiding. For some reason I can still see other old office apps in there and it won't let me uninstall them, but as long as the main office app is gone then it's sorted. Oh and fk Microsoft for not helping with this.

    Finally resolved this issue on my device, but I had a weird scenario with my office apps. Adding this here in case anyone might have the same scenario.

    PROBLEM

    After upgrading my Samsung S22 Ultra to OneUI 7 Android 15 update, my office apps won't open.

    Clicking on an office app (word, excel, etc.) an android permission splash screen appears and then quickly closes app.

    Attempted to install office mobile from the Samsung mobile store, but encountered the following error: "unable to install app because it conflicts with existing package"

    Checked settings -> apps and verified that office, m365 copilot was not installed

    I also attempted to install an office mobile app apk, but encountered the same error.

    CAUSE

    It turns out I had older versions of office apps installed as secure apps (this may have been due to an old work policy from a previous job??, but not certain)

    I was even able to run the office mobile app and other apps from the secure folder successfully.

    SOLUTION

    On device, went to Settings -> Apps -> Samsung App Settings -> Secure Folder -> Apps

    Uninstalled all office apps: Office mobile, word, excel, etc.

    After unisntalling from secure folder, I was able to install and run the Office mobile app enabling the permissions as per recommended forum answers.

    Was also able to successfully install and open other office apps.

    Also, no issues encountered after uninstalling office mobile and replacing it with microsoft co-pilot app.

    Hope this scenario can help someone.
