What the official warning actually says
Northwell’s browser check explicitly says myExperience is incompatible with Internet Explorer 11 and recommends Microsoft Edge or Google Chrome. It also lists a Help Desk contact. This is a browser compatibility statement; it does not prove that a password is wrong, that an account has been disabled or that an employee lacks an assigned task.
Use a browser supported by your employer’s current device policy. The official notice contains instructions referring to particular Windows versions; those are historical details on a public page, not a reason for this independent publisher to prescribe an outdated operating system. If your managed device is restricted, ask IT rather than installing unapproved software.
Identify where the warning appears
A warning shown before credentials is a different failure from an error after the employer’s identity step. Record the browser and the point at which navigation changes. If a colleague can open the public page on a different device, that does not prove your private account works; it only shows that a public route can load in that environment.
A current Chrome or Edge window can rule out the specific IE11 warning, yet other device or network issues remain possible. This guide does not assert that changing a browser fixes all access problems. Avoid copying the page into a third-party “browser compatibility checker” that asks for employee details.
A controlled comparison
On an approved device, start at Northwell’s published entry in a current employer-approved browser. Note whether the warning, sign-in screen or error appears. If a second approved browser is available, compare the stage reached, not sensitive on-screen account information. Do not disable endpoint protection or policy extensions to force a page to load.
If both current browsers fail before identity, report the observed page and time to official IT support. If the sign-in rejects a credential, move to credential assistance. If the session opens but a task is absent, post-login triage is the more useful branch.
Cookies, sessions and caution
Sign-in flows may use browser sessions and redirects. A stale tab can preserve an expired attempt. Starting again at the official entry in a new tab is a modest test; deleting all browser data on a managed machine can have side effects, so follow the employer’s instructions before broad cleanup. Never paste a session URL into a public troubleshooting site.
The cookie controls on this independent publication govern its own optional reading preference only. They do not change Northwell’s authentication cookies or fix its login. Our access map explains why the same browser can visit different Northwell destinations with separate sessions.
Escalate the exact symptom
Northwell’s browser page publishes an IT Help Desk number. Reopen the official page to confirm that contact before calling. Report the browser name, operating environment, approximate time and first failing screen, without reading out a password or one-time code.
This is not a Northwell browser certification test. The public page was reviewed on the article’s source-check date, and your employer’s IT requirements may evolve. An authorized team can evaluate device policy, identity status and service availability in a way this article cannot.
What a comparison can prove
Suppose the official entry displays the IE11 warning on an old browser but loads an identity prompt in an employer-approved Edge window. The comparison supports the narrow conclusion that the earlier warning was browser-dependent. It cannot show that the account is active, that a role has permission or that every downstream task is available. Stop at the first later failure and describe it accurately.
Suppose the page fails in two approved browsers on one managed laptop. That finding narrows the local environment but is not proof of a public outage; network and device policies may apply. Give official IT the time, device context and first screen that fails. Avoid disabling a managed security extension to make a one-off test pass. This is one of the cases where local observation and employer-controlled diagnostics have different limits.
When an error looks like a browser issue
An unsupported-browser notice can appear before the service evaluates your account. The right report includes the exact notice and browser family. It should not say that a password is invalid when no password was entered. If the page later displays an identity rejection in a supported browser, that later event is new evidence. Give support both observations in order instead of presenting a single assumed cause.
