How to Fix Microsoft 365 Installation or Sign-In Fails on Mac (Error 2602)
Question details
The user is unable to successfully install or sign in to Microsoft 365, experiencing a network timeout commonly indicated by Error 2602.
- Product
- Microsoft 365
- Device & OS
- Mac
- Scenario
- Installing Microsoft 365 applications or signing in to activate the software on a Mac device.
- Observed behavior
- The installation fails after the download completes, or signing in triggers Error 2602, stating that the network timed out.
Verify that your Mac is connected to a stable internet connection and that you have an active Microsoft 365 subscription tied to the account you are using.
Temporarily Disable VPNs, Proxies, and Antivirus Software
Network timeout errors like Error 2602 are often caused by third-party security software or VPNs blocking communication with Microsoft's activation servers.
If you are using a VPN, proxy server, or third-party antivirus program, it may intercept the network traffic required for Microsoft 365 to verify your license. Disabling these temporarily can help identify the block.
Open your VPN application or navigate to Apple menu > System Settings > Network, and temporarily disconnect any active VPN profile.
In System Settings > Network, select your active Wi-Fi or Ethernet connection, click Details, go to the Proxies tab, and toggle off any manual proxy configurations.
If you are running a third-party antivirus or firewall, open the application and temporarily pause its real-time protection shields.
If the error persists, connect your Mac to a different Wi-Fi network or a mobile hotspot, restart your browser, and attempt the sign-in again.
Verify Installation Source and macOS Compatibility
Conflicts can arise if the installation source is corrupted or if the current macOS version is not fully supported by the downloaded Microsoft 365 installer.
Use WPS Office as a Free and Hassle-Free Alternative on Mac
If you continue facing Microsoft 365 installation errors or sign-in timeouts like Error 2602, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative to Microsoft Office that installs easily on your Mac without complex network activation hurdles.
- 1. Download the installer: Visit the official WPS Office website and download the Mac version.
- 2. Install the application: Open the downloaded file and drag the WPS Office icon into your Applications folder.
- 3. Open your files: Launch WPS Office and instantly open your existing Microsoft Office documents without format loss.
Frequently Asked Questions
What does Error 2602 mean in Microsoft 365 on Mac?
Error 2602 is a network timeout error indicating that Microsoft 365 applications cannot reach the activation servers to verify your account or subscription. It is typically caused by local network restrictions, VPNs, or proxy configurations.
Can a university account cause activation issues on my personal Mac?
Yes. University accounts often have strict device management, licensing policies, or limited device quotas. If your subscription is provided by your school, you may need to verify with your IT department that your personal device is authorized for activation.
How do I completely remove Microsoft 365 before attempting a reinstall?
To fully uninstall, open the Applications folder and move all Microsoft apps (Word, Excel, PowerPoint, Outlook) to the Trash. You should also open the Library folder and remove any Microsoft-related cache or container files before attempting a fresh install.
