Fixing issues accessing your new CUNY mailbox

If you're having trouble accessing your new CUNY mailbox in Outlook for Windows, follow the steps below in order. This resets your Outlook profile, clears saved CUNY credentials, and removes old cached data so Outlook can reconnect cleanly.

Step 1: Close Outlook

Make sure Outlook is fully closed before continuing.

Step 2: Open Control Panel

Click the Start Menu and search for “Control Panel,” then open it.

Search for “Control Panel” from the Start Menu

Step 3: Search for “Mail”

In the top-right search box of Control Panel, type “Mail” and select “Mail (Microsoft Outlook)” from the results.

Search “Mail” in Control Panel

Step 4: Remove existing Outlook profiles

In the Mail Setup window that opens, click “Show Profiles.”

Mail Setup window — click “Show Profiles…”

• Select each profile in the list, click Remove, and repeat until the list is empty.
• Click OK.

Remove all profiles from the list, then click OK

Step 5: Clear saved CUNY credentials

Open Control Panel again and search “Credential Manager” in the top-right search box.

Search “Credential Manager” in Control Panel

• Select “Manage Windows Credentials.”
• Delete any entry that references:
  • webmail.ccny.cuny.edu

Remove any entry for webmail.ccny.cuny.edu

• • SSO_POP_Device

Remove any entry for SSO_POP_Device

• • Any other entry containing ccny.cuny.edu or login.cuny.edu

Step 6: Close the window

Close the Credential Manager window.

Step 7: Clear cached Outlook data files

Open the Start Menu and search for “File Explorer.”

Search for “File Explorer” from the Start Menu

• In the address bar at the top, type: %localappdata%\Microsoft\ and press Enter.

Type %localappdata%\Microsoft\ in the address bar

• Open the IdentityCache folder and delete the files inside it.
• Go back, then open the OneAuth folder. Inside it, open each of these two folders and delete the files within:
  • Accounts
  • Blobs
• Go back, then open the Outlook folder. Delete any files in that folder ending in the following extensions:
  • .xml
  • .nst
  • .ost
• Go back one more time. If a folder named OLK exists, delete it.
• If you don't see file extensions listed, turn them on: in File Explorer, go to View → Show, and check “File name extensions.”

View → Show → File name extensions

Step 8: Close the window

Close the File Explorer window.

Step 9: Set up Outlook again

Open Outlook. You'll be prompted to create a new profile — enter a name for it and click OK.

Enter a name for your new profile

• Enter your CUNYFirst ID (your CUNY email address) and follow the prompts to log in with your CUNY credentials.

Enter your CUNY email address to sign in

• If everything is successful, your mailbox will begin to populate with your email.

Step 10: Still having trouble?

If you're still encountering issues after completing these steps, contact the service desk at 212-650-7878 or servicedesk@ccny.cuny.edu for additional troubleshooting.

We have finalized the date for the CUNY email migration. The migration is scheduled to begin on Wednesday, August 12, 2026. As part of the migration process, CCNY email services will become unavailable beginning Tuesday, August 11, at 6:00 p.m. while mailboxes are transitioned to Microsoft 365.

IMPORTANT INFORMATION



Setting up Multi-Factor Authentication

If you have not set up or used your Microsoft Multi-Factor Authentication (MFA) within the last two months or if you recently changed your phone and/or have not yet configured your MFA, you must do so before your scheduled email migration.

Failure to verify your MFA before migration means longer wait time and prevent you from accessing your CUNY email and Microsoft 365 services after your mailbox has been migrated.

Please complete the following before your migration:

• Sign in to Microsoft 365 with your CUNYfirst login credentials.

• Confirm that you receive the authentication prompt and can successfully complete the sign-in process.
• If you have changed or replaced your mobile device recently, verify that your authentication method is still up to date.
• If you experience any issues with MFA, contact the IT Service Desk before your scheduled migration date so we can assist you.

If you are having issues with setting up your Microsoft Multi-Factor Authentication (MFA), you can attend one of the info session scheduled for next week, see information below.

Additional Info sessions

To ensure everyone has another opportunity to prepare, we have scheduled two additional information sessions on Monday, August 10 and Tuesday, August 11. If you or members of your staff have any remaining questions about the migration, we strongly encourage you to attend one of these sessions.

Information Session Schedule

Monday, August 10 | 1:00 PM – 2:00 PM

Tuesday, August 11 | 1:00 PM – 2:00 PM

Zoom link: Please refer to the broadcast announcement.

Passcode: Please refer to the broadcast announcement.
