How to Fix Safari Client Request Loop Error When Signing In to Office.com
Question details
The user is experiencing a continuous client request loop error preventing them from accessing their Office.com account via the Safari browser.

- Product
- Office.com
- Device & OS
- iOS 16.3.1 (iPad)
- Scenario
- Attempting to sign in to the Office.com web portal using Safari on an iOS device.
- Observed behavior
- Safari blocks the login process and displays the error message: "The server terminated an operation because it encountered a client request loop."
Before adjusting your browser settings, ensure you have your correct Microsoft account credentials handy, as you will need to re-enter them after clearing your browser data.
Adjust Safari Privacy Settings and Clear Cache
Disabling Safari's cross-site tracking prevention and clearing outdated website data can resolve authentication cookie blocks that cause login loops.
Safari's strict privacy features can sometimes interfere with Microsoft's multi-step authentication process, causing the server to repeatedly request login cookies until it times out.
Open the 'Settings' app on your iPad, scroll down the left menu, and tap on 'Safari'. Under the 'Privacy & Security' section, toggle off the switch for 'Prevent Cross-Site Tracking'.
Still within the Safari settings page, scroll down and tap 'Clear History and Website Data'. Confirm the action to remove outdated cache and cookies.
Force close the Safari app, reopen it, navigate to Office.com, and attempt to sign in again.

Use an Alternative Web Browser
If adjusting Safari settings does not resolve the issue, using a different browser with default tracking settings can bypass the loop.
Avoid Browser Login Loops Entirely with WPS Office
If you are tired of dealing with web browser errors, infinite login loops, and cloud sync issues, WPS Office offers a powerful, localized alternative. Edit your documents directly on your device without relying on complex web portals.
- 1. Download and install: Get WPS Office for free from the App Store on your iPad or from the official WPS website for your computer.
- 2. Open your files directly: Launch the WPS Office app and open your existing documents locally without needing to authenticate through a web browser.

Frequently Asked Questions
Why does Safari say it encountered a client request loop?
This error happens when Safari's privacy settings block the necessary authentication cookies required by Microsoft's login servers. The server continuously attempts to request these cookies, causing the page to reload repeatedly until it throws an error.
Is it safe to disable Prevent Cross-Site Tracking on my iPad?
Yes, it is generally safe to temporarily disable this feature to allow legitimate websites like Office.com to authenticate your login. You can easily turn it back on in your Safari privacy settings once your sign-in is successful.
What should I do if clearing the cache does not fix the Office.com login loop?
If clearing cache and adjusting tracking settings fails, take a screenshot of the complete error message for support reference. Then, switch to a different browser like Chrome or Edge, or use an offline document editor like WPS Office to handle your files.
