Hello

I'm trying to sign up for the Microsoft Partner Center, but when I choose how to collaborate, I encounter the following error:

"Can't access the site"

I use Opera, Google, Microsoft Edge

I have tried incognito mode and cleared the cache but the problem persists;

VPN and proxy server are disabled;

The Internet connection is stable;

I'm using a work account

Two-factor authentication (MFA) is enabled.

Due to this error, I am unable to complete my registration and move forward with the process of joining the Microsoft AI Cloud Partner Program.

I would appreciate your help in identifying the cause of this issue and providing guidance on how to successfully complete your registration.

If you need more information about my account or browser, I'm willing to provide it.

Thank you for your support!

Dear [@Green Isabelle],

I understand you are receiving the "Can't access the site (dopht=101)" error while selecting your collaboration option during the Microsoft Partner Center registration.

Since you have already cleared your cache, tried multiple browsers, and disabled local VPNs, please try the following steps to resolve this:

Step 1: Test on a Different Network:

  • Please disconnect from your current office/home Wi-Fi or corporate network and connect your device to a mobile network hotspot (or a completely external network). Corporate firewalls or strict network security rules often block the dynamic redirect URLs used during Partner Center tenant setup.

Step 2: Verify Global Admin Permissions:

  • Ensure that the work account you are using has Global Administrator permissions in your organization's Microsoft Entra ID (formerly Azure AD) tenant.

Step 3: Try an InPrivate Window on Edge via Mobile Hotspot:

  • Once connected to your mobile network, open an InPrivate window in Microsoft Edge and navigate directly to Partner Center Enrollment.

In that case, please provide a full screenshot of the error page, including the URL in the address bar (please remove any personal information if applicable) so I can review it and offer further suggestions.

For official guidance on registration prerequisites, you can review the Troubleshoot Partner Center account issues documentation.

Please let me know if switching to a mobile network resolves the redirect for you.

    For this Partner Center registration access issue, use this path:

    1. Confirm the account type. Microsoft Collaborate registration in Partner Center requires a Microsoft Entra ID organizational account with the Global Administrator role. If the account does not have Global Administrator privileges, registration can fail with identity validation or access issues.
    2. Verify the correct directory and account are selected in Partner Center. If the sign-in lands on the wrong Partner Center context, select the badge icon in the upper-right corner and switch to the directory normally used. Then use the account selection control in the left navigation to choose the correct account.
    3. Check for work/personal account overlap. If the same email name exists as both a personal Microsoft account and a work account, Partner Center sign-in and invitation flows can fail. In that case, sign in with the work account for Partner Center. If the corporate email is linked to a personal Microsoft account, the documented workaround is to rename the personal Microsoft account.
    4. Retry in a clean browser session. Since cache clearing and private browsing were already tried, repeat the test only after confirming the correct directory/account selection and account type. The documented browser steps are:
      • In Edge: Settings and more → Settings → Privacy and security → Choose what to clear → clear Cookies and saved website data and Cached data and files.
      • In Chrome: Customize and control Google Chrome → More tools → Clear browsing data... → clear Cookies and other site data and Cached images and files.
    5. If registration still fails, use support outside Partner Center sign-in. If access to Partner Center cannot be completed, a support ticket can be created without signing in using the Partner Center support flow.
    6. If the problem is specifically MFA or account access related, use the account recovery path.
      • If locked out or password reset is needed, use the security information and mobile-device password reset flow if enabled by the global admin.
      • If there is no available global admin, or the only global admin is locked out, the documented Data Protection support paths apply.
    7. Prevent future lockouts. Create an emergency access (break-glass) account in Microsoft Entra to avoid being blocked from the tenant if standard sign-in fails.

    Based on the described symptoms, the most likely checks are:

    • wrong directory/account selected in Partner Center,
    • using a work account without Global Administrator privileges,
    • or a personal/work account overlap for the same email identity.
    AI-generated content may be incorrect. Read our transparency notes for more information.
