Question

Issue reconnecting Microsoft Outlook to Zapier

Hi everyone,

I’m currently experiencing an issue while trying to reconnect my Microsoft Outlook account to Zapier and was hoping someone here might have encountered something similar or has suggestions.

Zapier prompts me with: “Reconnect Microsoft Outlook to your Zapier account.”
When I click “Reconnect,” I’m redirected to the Microsoft login page. However, after signing in successfully, the connection is not completed. I’m sent back to Zapier, but Outlook remains disconnected.

Additionally, when I click on “If you have an administrator account, sign in with that account,” nothing happens at all — there’s no redirect and no error message.

As a result, I’m currently unable to reconnect Outlook and my Zaps are not running.

Here’s what I’ve already tried:

  • Reconnecting using an incognito/private browser window

  • Clearing browser cache and cookies

  • Logging out and back into Microsoft

  • Verifying admin permissions

Unfortunately, none of these steps resolved the issue.

Has anyone experienced this before or knows what might be causing it?
Any help would be greatly appreciated!

Hey there ​@JK7, welcome to the Community! 🎉

Sorry to hear that your Microsoft Outlook connection is not reconnecting. Thanks so much for sharing the steps you’ve already taken in trying to troubleshoot this, it’s super helpful! 🤗

I had a look on this side but couldn’t find any similar reports of this happening. Judging by the Getting Started guide here it seems like the app only works for Microsoft 365 Business/Enterprise accounts with an Exchange Online mailbox. If you’ve already got those in place, it could be that another admin may have disabled or restricted third party app access after you initially added the account.

If that’s the case, can you try re-enabling third party app access in your Microsoft account and let us know if that then allows you to reconnect successfully?

If third-party app access is already granted then I’d recommend reaching out to our Support team to take a closer look into the error logs for your Zap. Sometimes there’s additional information in the error logs that can help to shed some light on why the connection isn’t going through.

Keep us posted on how you get on with that!

Hello ​@JK7 
That’s frustrating, especially with Zaps not running.

When Outlook reconnects but doesn’t complete, it’s usually:

• A Microsoft org security or consent policy blocking OAuth
• A stuck or stale Outlook connection in Zapier
• Browser extensions or tracking protection interfering with the redirect

A few quick things to try:

  1. Use a completely different browser, not just incognito

  2. Temporarily disable ad blockers or strict tracking protection

  3. In Microsoft “My Apps,” remove Zapier’s access, then reconnect

  4. Remove the Outlook account under Connected Accounts in Zapier and add it fresh

If it’s a work account, your M365 admin can check Entra ID sign in logs for a blocked consent attempt.

If it still fails, Zapier Support can usually see the exact auth error on their side and help unblock it.

Got the same problem with a clients account I was trying to connect.

 

Is the email personal or company email?

 

Outlook gives you 2 options to choose from Personal Email or Company Email, if one of them gives you this error, go to the next one and it should work.
