i am having trouble with outlook. it opens and within seconds it closes saying permission denied. i have tried repair, didnt work, tried reset and now outlook app has disappeared

Reinstall New Outlook for Windows from Microsoft Store first; the reset has left the app unavailable, so repeating Repair or Reset will not help.

Reinstall New Outlook

1. Restart the computer.
2. Open Start, search for Microsoft Store, and open it.
3. Search for Outlook for Windows.
4. Select:
   • Get or Install if Outlook is absent.
   • Open if the Store says it is already installed.
5. Open Outlook and follow the prompts to add the email account if it was not restored automatically.

Microsoft documents Microsoft Store as the reinstall method for New Outlook; it requires Windows 10 version 17763.0 or later.^1^

If Outlook does not appear in Store search, open Microsoft Store → Library, locate Outlook, and select Install.^2^

If Microsoft Store cannot install it

Reset the Store cache—not Outlook:

1. Press Windows key + R.
2. Enter wsreset.exe.
3. Select OK.
4. Wait for the blank Command Prompt window to close and Microsoft Store to reopen.
5. Search for Outlook for Windows and install it again.^3^

If “permission denied” returns

First test the same mailbox through its webmail site:

• If webmail also rejects the sign-in, resolve the account password or verification problem with the email provider.
• If webmail works, note whether Outlook requests a Microsoft, Gmail, Yahoo, iCloud, or other provider password. Third-party providers can require an app password, two-step verification, or permission for mail applications.^4^

If Outlook stays open long enough, use Settings → Accounts → Your accounts → Manage, remove the affected account, and add it again. Do not repeat Repair or Reset, since both have already failed.

If it closes before account settings can be reached:

1. Close Outlook, Teams, and other Microsoft applications.
2. Press Windows key + R, enter appdata, and press Enter.
3. Open Local → Microsoft.
4. Delete the Olk and OneAuth folders.
5. Restart Windows and reopen Outlook.

Those folders are recreated when Microsoft applications reopen; this cleanup is a fallback for New Outlook launch failures that persist after repair or reinstallation.^5^

If the error persists, record its exact wording—without including the email address or password—and check Event Viewer → Windows Logs → Application immediately after the crash for the newest Outlook-related event. That information distinguishes an account-access rejection from an application crash.

If “reset” meant Reset this PC, rather than resetting the Outlook app, the appropriate recovery is to reinstall Microsoft 365/Office because a Windows push-button reset can remove Outlook and other Office applications.^6^
