Most often this [is either a Microsoft](https://todayfixtech.com/fix-microsoft-365-login-issues/) service incident or a local/tenant problem you can fix quickly by checking Microsoft 365 Service health, trying a few client-side fixes (browser, cache, app updates), and then having an admin check licensing, group provisioning and Conditional Access. Follow the ordered checks below to isolate the cause and restore access fast. ## Is Planner down for everyone or just you ```text Planner unavailable Something went wrong, we can't load Planner right now ``` Symptom When it appears: right after loading `https://planner.microsoft.com`, opening Tasks by Planner in Teams, or the Planner tab on a SharePoint page. [How to check Microsoft](https://todayfixtech.com/microsoft-365-mobile-app-features/) 365 Service health 1. Open the Microsoft 365 admin center and go to Health > Service health. ```text Microsoft 365 admin center > Health > Service health ``` Settings path 1. Look for an incident or advisory affecting Planner. It may be listed under “Microsoft Planner”, “Microsoft 365 Groups”, “SharePoint”, or “Exchange” depending on the root cause. Staged rollouts or partial incidents can show only some tenants or regions affected. Interpreting staged rollouts and timing - A clear Service health page means Microsoft has not confirmed a widespread incident, but outages sometimes start before Microsoft posts an incident. If Service health is clear but many users are affected, run the client-side checks below and recheck Service health after 10–15 minutes. Third-party outage trackers - Use third-party trackers only to corroborate widespread reports; they cannot diagnose tenant-specific or configuration issues. What to do next based on findings - If Microsoft reports an incident: monitor the incident, inform users, and wait for Microsoft updates. - If there is no incident: continue with the client-side and admin checks below. ![A person checks a smartphone while a laptop on the desk shows a blurred loading indicator on its screen.](https://tse1.mm.bing.net/th?q=person%20standing%20in%20front%20of%20a%20laptop%20on%20a%20desk%20and%20glancing%20at%20a%20smartphone%20while%20the%20laptop%20screen%20shows%20a%20blurred%20loading%20indicator%2C%20photo&w=624&h=352&c=7) ## Quick tests that fix most 'Planner unavailable' errors Before admin actions, try these client-side tests in order. Each isolates a common cause: browser state, cached tokens, client versions, or the network. 1. Open Planner in a private / Incognito / InPrivate window ```text Browser menu > New InPrivate window (Edge) / New Incognito window (Chrome) ``` Settings path Expected result: Planner loads. What it means: a browser extension, cached credential or cookie blocked Planner. 1. Clear the browser cache and cookies (site-specific if possible) ```text Browser settings > Privacy & security > Clear browsing data > Cached images and files + Cookies and other site data ``` Settings path Expected result: Planner loads after sign-in. What it means: stale tokens or corrupted cache caused authentication or resource loading failures. 1. Try a different browser Expected result: Planner loads in another browser. What it means: a browser-specific extension, policy or setting blocks Planner in the first browser. 1. Sign out of Office 365 and sign back in Expected result: Planner loads after reauthentication. What it means: session token expired or account context changed. 1. Update the Teams desktop app or Planner mobile app - In Teams: Help > Check for updates, then restart Teams. Expected result: Planner tab or Tasks by Planner appears and works. What it means: an out-of-date client had a bug or an authentication mismatch. 1. Restart the device and retry Expected result: Planner loads. What it means: transient OS or network stack issue resolved. Notes - After each step, test the web app at `https://tasks.office.com` or `https://planner.microsoft.com` to confirm behavior. - If an extension is suspected, disable them one by one and retry to find the culprit. ## Account and tenant checks admins must do next Before you start - Applies to: Microsoft Planner (web, Tasks by Planner in Teams), current Microsoft 365 tenants. - Privileges needed: Global admin, Exchange admin, or Groups admin to inspect groups and licenses. - Restart/backup: no restart or backups required for the checks listed here. - Safe checks to run first: verify the affected user’s license, and reproduce the issue with a second user. 1. Confirm the user has a Planner-capable license Steps: 1. Open Microsoft 365 admin center > Users > Active users. 2. Select the affected user and open Licenses and apps. ```text Microsoft 365 admin center > Users > Active users > [user] > Licenses and apps ``` Settings path Expected result: The user has a license that includes Planner (for example, [most Microsoft 365 business](https://todayfixtech.com/microsoft-365-updates-features/) and enterprise plans). What it means: if missing, assign a suitable license and ask the user to sign out and sign back in. 1. Check Office 365 Group provisioning for the plan Steps: 1. In the admin center go to Teams & groups > Active teams & groups > Microsoft 365 groups and search for the group linked to the plan. ```text Microsoft 365 admin center > Teams & groups > Active teams & groups > Microsoft 365 groups ``` Settings path Expected result: The group exists and shows no provisioning errors. What it means: if the group is missing or shows provisioning failed, Planner cannot load that plan. Recreate or repair the group or restore it if you have a backup. 1. Verify Planner is enabled for the tenant Steps: 1. In Microsoft 365 admin center go to Settings > Org settings > Services & add-ins and find Planner. ```text Microsoft 365 admin center > Settings > Org settings > Services & add-ins > Planner ``` Settings path Expected result: Planner is enabled for the organization. What it means: if disabled, enabling it will restore access for licensed users; users must sign out and sign back in. 1. Check group membership and mailbox / SharePoint provisioning - A Microsoft 365 Group needs a mailbox and a SharePoint site to be fully healthy. In the Exchange admin center, check the group and ensure it is not in a failed state. If the group was just created, allow 10–20 minutes for provisioning. What to do if provisioning is delayed - Wait 10–20 minutes and retry. If the group remains unhealthy, collect the group name and provisioning error details and escalate to Microsoft support. ## Network, Conditional Access and security features that block Planner Planner depends on Azure AD auth and several Microsoft services. Network or security controls can block it; test by changing network or client to isolate the block. Common culprits and simple tests - Conditional Access or MFA: try from a device or network not subject to the policy (home or mobile). If it works there, review Conditional Access policies targeting Office 365 apps. - Corporate proxy/firewall or DNS: try a cellular hotspot or home network. If Planner works on a different network, your corporate network likely blocks required endpoints. - Browser extensions or privacy features: test in Incognito/InPrivate with extensions disabled. Tests and one-line fixes 1. Try a cellular network or home Wi‑Fi Expected result: Planner loads. What it means: corporate network or proxy is blocking traffic; work with your network team to allow Microsoft endpoints. 1. Bypass proxy (temporary test) Only bypass proxy for diagnostic purposes and follow your org policy. Steps: 1. Temporarily set your device to bypass the corporate proxy or use a direct connection. Expected result: Planner loads. What it means: proxy is filtering requests; add exceptions for Microsoft 365 endpoints. 1. Disable browser extensions Expected result: Planner loads without the extension. What it means: extension blocks cookies, scripts, or third-party requests; remove or whitelist `planner.microsoft.com`. 1. Check Conditional Access policies (admin) Steps: 1. In the Azure AD portal go to Security > Conditional Access and review policies that apply to the affected users or Office 365 apps. ```text Azure portal > Azure Active Directory > Security > Conditional Access ``` Settings path Expected result: No policy is denying access to Planner for the affected user. What it means: if a policy denies access, adjust it or create an exception for Planner or the user scenario. DNS issues - Test DNS by resolving `planner.microsoft.com`; if resolution fails or points to an internal proxy IP, correct DNS records or proxy rules. What to allow in firewalls/proxies - Allow Microsoft 365 endpoints used by Planner, Microsoft Graph, SharePoint and Exchange. If you can’t change rules yourself, provide the network team with the symptom, traceroute/DNS results and failure times. ## How to verify the problem is resolved and what to do if it isn’t Verify the fix 1. Open a plan in the affected environment and confirm it loads. 2. Create a simple task and save it. 3. Open the same plan in Teams (Tasks by Planner) and refresh. 4. Recheck Microsoft 365 Service health to ensure no ongoing incident. Expected results: - Plan loads, task creation succeeds, and changes appear in Teams. Collect diagnostics if it’s not fixed - Capture: the exact error message (the exact message varies), a screenshot, time and time zone, affected user UPN, tenant ID, plan/group name, and steps to reproduce. - From the client: browser console network errors, F12 developer console logs, and a HAR file if possible. Admin diagnostics 1. In Microsoft 365 admin center, run Service health diagnostics or Support and troubleshooting tools for the user and collect the output. 2. Use Azure AD sign-in logs to find failed auth attempts and note Conditional Access evaluations. When to open a Microsoft support ticket - Open a ticket when you have reproducible steps, the issue affects multiple users and tenant-level fixes haven’t worked, or Service health shows an incident requiring Microsoft escalation. Include the diagnostics above in the ticket. Short-term workarounds - Use Tasks in Teams if Planner web is unavailable but Teams works. - Use the Planner mobile app if web access is blocked. - If tenant-specific and urgent, create a temporary plan in another tenant or ask an unaffected user to share a plan externally, understanding the security implications. ## Preventing future 'Planner unavailable' surprises Practical steps admins and users can take - Monitor Service health and set up incident alerts in the Microsoft 365 admin center so you receive notifications when Planner or dependent services have issues. - Document which licenses include Planner and automate license assignment for new users. - Keep a list of Conditional Access policies and add explicit exceptions for Planner/Tasks if your policies restrict browsers or locations. - Work with network teams to allow the Microsoft 365 endpoints Planner uses and keep a short checklist for DNS and proxy diagnostics. - Communicate maintenance windows to users and provide alternative task-tracking options (Teams Tasks or mobile Planner) during incidents. - Periodically test Planner access from a non-corporate network to confirm policies and network changes haven’t blocked Microsoft services. ## Common quick questions people ask next Q: Does Planner need an Office 365 Group? A: Yes. Each Planner plan is backed by a Microsoft 365 Group and requires the group to be healthy and provisioned. Q: Can I use Planner with a consumer account? A: No. Planner requires a work or school account on a Microsoft 365 tenant; consumer (personal) Microsoft accounts are not supported. Q: Why does Planner work in Teams but not planner.microsoft.com? A: Teams may use a different authentication flow or cached token. If Teams works but the web portal fails, the cause is often browser-related (extensions, cookies, SSO) or a Conditional Access rule that targets browser clients. Q: When should I contact Microsoft support? A: Contact support after you’ve confirmed no public incident, tried client-side and tenant checks, collected diagnostics (error text, screenshots, HAR, Azure AD sign-in logs), and the issue affects multiple users or critical workflows. ## Conclusion If Microsoft reports an incident, monitor Service health and inform users. If not, run the client-side checks, confirm licenses and group provisioning, and rule out network or Conditional Access blocks. Gather diagnostics before opening a Microsoft support ticket. Use Tasks in Teams or the Planner mobile app while you restore web access. ## Frequently Asked Questions ### Why does Planner say 'Something went wrong' even after I sign in? That usually means cached credentials, browser state, or a Conditional Access policy is blocking the session. Try an Incognito/InPrivate window, clear cookies for Microsoft domains, and check Azure AD sign-in logs for Conditional Access failures. ### How long should I wait for Microsoft to fix a reported Planner outage? Microsoft posts progress notes and estimated times to resolution on the Service health incident when available. If Service health does not list an incident, start local troubleshooting after 10–15 minutes of confirmed widespread reports. ### Can network DNS or proxy changes cause Planner to become unavailable suddenly? Yes. DNS misconfiguration or a proxy/firewall rule that blocks Microsoft endpoints will prevent Planner from loading. Test by switching to a cellular network or bypassing the proxy temporarily for diagnosis.
