Hello,

When I compose an email and want to paste an item, clicking on the pad to bring up the menu to paste the item, the Outlook application closes by itself.

    Hi Quinn,

    For the best possible assistance, can you share more details about your situation? I greatly appreciate your cooperation and understanding.

    • Which device and operating system are you using? Is is a Windows or macOS or something else?
    • Does the keyboard shortcut (Ctrl + V or Cmd + V) work?
    • Can you give it a test and see whether the issue occur with plain text copied from Notepad or Notes?
    • Does Outlook show an error message, or does it disappear without warning? If there is an error message, please share a screenshot or full wording of it

    I want to ensure I have clear details about your situation so I can provide appropriate guidance/information.

    Should you have any further questions or need additional assistance, please feel free to share them in the comment below. I'm very happy to help.

    Thank you again for your patience and understanding. Hope to hear from you soon.

    This matches a known Outlook for Microsoft 365 issue where Outlook can crash when composing or authoring, especially if an older Office language pack is installed alongside a newer Microsoft 365 build.

    Check this first:

    1. Open Windows Event Viewer and look in the Application Log for Event 1000 or Event 1001.
    2. Confirm whether the faulting module is a language DLL such as mscss7it.dll, mscss7ge.dll, or another mscss7xx.dll file.
    3. If the module version is something like 16.0.4288.1000, that indicates an older MSI language installation.

    Fix steps:

    1. Go to Windows Settings > Apps > Installed Apps.
    2. Find the old Office language installation and uninstall it.
    3. Reinstall the language pack by following Step 2: Configure Microsoft 365 language in Language Accessory Pack for Microsoft 365.

    Important: uninstalling and reinstalling language packs changes Office language components, so close Office apps first before making the change.

    If the crash happens specifically while drafting or typing, this is the documented workaround in the current known issue.
