Microsoft 365 web apps

Make Microsoft 365 web sessions easier to verify.

Microsoft 365 web apps can sign users out after organization-configured idle periods. Session Activity Helper gives Chrome users a visible, browser-only way to test supported Microsoft 365 web tabs, run local activity, and save Pro profiles for repeat web workflows without claiming to change tenant policy.

Browser-only activity for supported pages. Session Activity Helper does not override site, workplace, school, browser, device-management, or admin-controlled session rules.

Why this workflow gets frustrating

Outlook on the web, SharePoint, OneDrive, admin portals, and Microsoft 365 web apps can all be affected by idle session rules.
Users may not know whether activity in one web app counts for another supported Microsoft 365 tab.
Tenant-wide settings, browser sessions, third-party cookies, and Conditional Access can make timeout behavior feel inconsistent.

How to test it safely

Open the exact Microsoft 365 web app tab that tends to time out.
Run Test this page before relying on browser activity.
Start a visible session and keep the green indicator enabled.
Confirm last pulse, active recipe, and support state before a long web workflow.
Use Pro profiles for recurring Outlook web, SharePoint, OneDrive, admin, or Microsoft 365 web app workflows.

Why Pro matters here

Save profiles for repeat Microsoft 365 web app domains and admin portals.
Use longer visible run windows for dashboards, documents, inbox triage, and admin work.
Export support diagnostics when a browser, iframe, cookie, or tenant setting makes behavior hard to explain.

Important limits

It does not change Microsoft 365 tenant settings, Conditional Access, SSO, browser cookie settings, or administrator-controlled idle session timeout policy.
It cannot guarantee every Microsoft 365 web app, tab, embedded view, or portal treats browser activity the same way.
It does not send messages, edit documents, bypass sign-in, move the OS cursor, keep Teams status active, or keep the device awake.

FAQ

Answers before you install.

The best customers understand the browser-only limits first. That makes support cleaner and Pro upgrades more durable.

Can Session Activity Helper prevent every Microsoft 365 web apps timeout?

No. It can help supported Chrome tabs stay visibly active, but it cannot override website, workplace, school, browser, device-management, or administrator-controlled session rules.

Does it move the real mouse cursor or keep the computer awake?

No. Session Activity Helper is browser-only. It sends visible browser activity on supported pages; it does not move the operating-system cursor or prevent device sleep.

What should I test before relying on it?

Open the exact web app tab you care about, run Test this page, start a visible session, and confirm the last pulse, active recipe, and support state in local diagnostics.

When is Pro worth it?

Pro is for repeat workflows: saved site profiles, longer run windows, advanced recipes, optional auto-start on saved domains, and exportable support diagnostics.

Next step

Install free, test the page, then save the workflow if it helps.

The fastest path is simple: add the extension, open the web app that times out, run Test this page, and start a visible session. Pro is for repeat sites and longer workflows.
