Device & OS: macOS
Scenario: Attempting to sign into a Microsoft account within the Outlook or OneNote desktop applications on a Mac.
Observed behavior: The application returns a Network Request Timed Out Error 2602 and blocks sign-in, even though the same Microsoft account logs in successfully via a web browser.

Solution 1Recommended

Isolate the Issue in a New macOS Profile

Creating a new user profile helps determine if the sign-in error is caused by corrupted settings or cache files in your current macOS account.

If Error 2602 persists despite standard troubleshooting, it is often tied to corrupted permissions or files specific to your main Mac administrator profile. Testing in a fresh profile can bypass these hidden conflicts.

Open macOS Users & Groups

Click the Apple menu in the top-left corner of your screen, select System Settings (or System Preferences), and navigate to Users & Groups.

Create a new Administrator account

Click the Add Account button, authenticate with your current password, and create a new user profile. Make sure to set the account type to Administrator.

Switch profiles and test

Log out of your current Mac profile, log into the newly created profile, launch Outlook or OneNote, and attempt to sign in. If it works, the issue is confirmed to be specific to your original profile.

Solution 2

Disable VPNs and Verify Date & Time Settings

Incorrect time settings or interfering VPN connections are common culprits for network request timeouts like Error 2602.

Solution 3

Clear the App Cache and Update Software

Outdated software or a corrupted local application cache can block Microsoft Office from properly communicating with sign-in servers.

Frequently Asked Questions

Why does Error 2602 only happen on my Mac app and not in the browser?

App-specific errors like 2602 usually stem from corrupted local cache files, conflicting system proxy settings, or macOS profile permission issues. Because web browsers do not rely on the same local application data or system-level connection protocols, the browser sign-in remains unaffected.

Will reinstalling Outlook fix Error 2602?

It might, but the error is often tied to hidden user profile settings or cache files that remain on your Mac even after standard uninstallation. It is highly recommended to clear the App Cache or test a new user profile before fully reinstalling.

What should I do if the error only occurs on my main Mac profile?

If Outlook signs in successfully on a new administrator profile, your main profile's cache or keychain permissions are likely corrupted. You may need to either migrate your files to the new working profile or use the Mac Disk Utility to repair system permissions.
