    Hello Ida Reynolds,

    I understand how concerning it is when Publisher suddenly prevents you from accessing files you still need. The previous answer already covers the main file-location, Safe Mode, add-in, and Office repair checks, so the following information will help narrow down the exact cause.

    As one additional check, please confirm the versions of Publisher and Windows:

    1. In Publisher, select File > Account > About Publisher and note the full product name and version.
    2. Press Windows key + R, enter winver, and press Enter to check the Windows version.
    3. Install any pending Office and Windows updates, restart the computer, and test the file again.

    Please also confirm:

    • Does Publisher open normally to a blank publication?
    • Can you create, save, close, and reopen a new .pub file?
    • When you open an affected file, does Publisher freeze, close unexpectedly, or display an error?
    • If an error appears, what is the complete message or error code?
    • Does this affect every .pub file or only files stored on the external drive?
    • Under File > Account, does the licence show Microsoft 365 or a perpetual version such as Publisher 2021?

    These details will help distinguish a damaged-file issue from a compatibility, installation, licensing, or Publisher access issue.

    Please share the results and the exact error message, if one appears, and we will help you determine the most appropriate next step.

    Please also note that Microsoft Publisher reached the end of its lifecycle in October 2026. Microsoft 365 subscribers may no longer be able to access Publisher on or shortly after October 1, 2026 as the removal update rolls out.

    Support for perpetual versions of Publisher ended on October 13, 2026. A perpetual version may continue to run, but it is no longer supported or receiving ongoing fixes. Therefore, the licence and Publisher version shown under File > Account are especially important in this case.

    I hope this helps. Please feel free to reply if you need further assistance. I'll be happy to help.

    Copy one affected .pub file from the external drive to the computer’s Documents folder, test that local copy normally, and then test the same copy in Publisher Safe Mode to separate a storage problem from a Publisher problem.

    1. Test the file locally

    1. Open File Explorer and locate an affected .pub file.
    2. Copy—do not move—the file to Documents.
    3. Disconnect the external drive using Safely Remove Hardware if applicable.
    4. Start Publisher normally and select File > Open > Browse, then open the copied file.

    Interpret the result:

    • The local copy opens normally: the external drive, USB connection, or its file system is the likely problem area. Try another USB port or another computer. If Windows reports the drive as corrupt, avoid saving new data to it until the files have been recovered; writing to it can overwrite recoverable data.^1^
    • The local copy still makes Publisher stop responding: continue with Safe Mode.

    Copying rather than moving protects the original. USB disconnection while a file is open can contribute to file corruption.^2^

    2. Test Publisher in Safe Mode

    1. Press Windows key + R.
    2. Enter:
    mspub /safe
    1. Press Enter.
    2. Confirm that Publisher’s title bar shows Safe Mode.
    3. Open the same copy in Documents.

    Microsoft documents this command specifically for starting Publisher without normal add-ins and startup customizations.^3^

    If it opens in Safe Mode

    An add-in or another setting disabled by Safe Mode is likely interfering:

    1. While still in Safe Mode, select File > Options > Add-Ins.
    2. At the bottom, select COM Add-ins under Manage, then select Go.
    3. Clear one add-in and select OK.
    4. Close Publisher and start it normally.
    5. Test the same local file.
    6. If Publisher freezes again, reopen it with mspub /safe, disable the next add-in, and repeat.

    Leave the problematic add-in disabled, remove it if unnecessary, or obtain an updated version from its publisher.^3^

    If it does not open in Safe Mode

    The problem is not likely to be an add-in. Repair Office next.

    3. Repair the Office installation

    Repairing Publisher repairs the entire Office suite.

    • Windows 11: Right-click Start > Installed apps. Find Microsoft 365, Office, or standalone Publisher, select … > Modify.
    • Windows 10: Right-click Start > Apps and Features. Select the Office product, then Modify.

    Run Quick Repair first. If Publisher remains unresponsive, return to the same location and run Online Repair, which is more thorough. Restart Windows afterward and retest the local file.^4^

    If only particular files fail

    Try an affected file on another computer that has Publisher. A similar Publisher case found that files failing on one machine opened on another, which can provide a temporary way to access them.^5^

    • If every .pub file freezes on this computer, focus on Publisher/Office repair.
    • If only files from one external drive fail, focus on that drive and preserve the originals.
    • If one specific file fails on multiple computers, that file may be damaged. The available Microsoft Open and Repair procedure applies to Word, Excel, and PowerPoint, not Publisher, so it should not be expected in Publisher.^2^

    If repair fails, reinstall Office only after confirming access to the Microsoft account or installation media associated with the Office license.
