Blank Screen and Codes Galore

Question

Blank Screen and Codes Galore

Isabella Kirkpatrick 0

I was trying to go to the Outlook app, and as I completed the login-in information on the pop-up, the pop-up stayed white, and didn't move on into the email. With this, I then tried using the web-browser version of Outlook, and I logged in, and it gave me a bunch of random coding. I really need to get into my email, as I am a college student, and I had been waiting for an email to complete my summer registration.

Follow these steps to restore access to the mailbox.

Close and restart Outlook

Fully close Outlook and any other Office apps.
Reopen Outlook and try launching the mailbox again.
If a hosted or embedded Outlook app (like To Do or another pane) shows a blank screen, restarting Outlook often clears the issue.

Clear cached storage for the Outlook add-in sign-in window If the blank screen appears when opening a Dynamics 365 or similar Outlook add-in sign-in popup:
Open Outlook on the web (OWA) or classic Outlook desktop.
Open the add-in that triggers the sign-in popup.
Right-click inside the add-in and select Inspect to open Developer Tools.
Go to the Application tab.
Under Storage, select Local Storage and delete all stored data.
Select Session Storage and delete all stored data.
Close Developer Tools.
Reopen the add-in; if the authentication window appears again, repeat the same Local/Session Storage deletion inside that window.
Close and reopen Outlook, then complete sign-in when prompted.
If using the new Outlook for Windows If the blank popup occurs in the new Outlook for Windows:
Ensure Outlook is fully closed in Task Manager.
Press WIN+R and run: olk.exe -devtools.
Use Developer Tools as above to clear Local Storage and Session Storage for the add-in and authentication window.
Restart Outlook and sign in again.
If Outlook on the web shows “random coding”

This can indicate the mailbox or Outlook web session is not loading correctly.
Sign out of all Microsoft sessions in the browser.
Clear the browser cache (Ctrl+Shift+Delete → Clear now).
Open a new InPrivate/Incognito window (Ctrl+Shift+N) and go to Outlook on the web again.
If the mailbox still will not load, contact the institution’s Microsoft 365/Exchange administrator, as the mailbox may be disabled or misconfigured even if the account sign-in still works.

If using Outlook mobile as a workaround

Install the latest Outlook mobile app and sign in there while troubleshooting desktop/web issues.
If sign-in fails on mobile, use the Microsoft sign-in helper or password reset tools linked in the Outlook mobile sign-in help article.

If access is still blocked after these steps, the college’s IT or Microsoft 365 admin must check whether the mailbox is disabled and re-enable it so Outlook and OWA can load it again.
