Connecting to Bing Ads
Before setting up the connector, verify your Bing Ads account already has campaign data on it so Polar has something to pull in.
Bing (Microsoft Advertising) only allows Polar to connect using a Microsoft account whose account type is set to "Personal" — not a work or school account. This is a Microsoft limitation, not Polar's, and it's the single most common source of Bing connection issues.
Important: this is about the account type, not which email address you use. You do not need a personal email address — you can keep using your work email, as long as the Microsoft account behind it is set to a Personal account rather than a Work/School account.
Check your Microsoft account type
Sign in to Microsoft Advertising, click the gear icon (Settings) in the bottom-left navigation, then select My settings.
Look for the "Signed in with" section, just below the Password field. It shows your current account type, with a "Switch to a work account" or "Switch to a personal account" link on the right.
If it offers to switch you to a work account, you're already on a Personal account — you're good to go. If it offers to switch you to a personal account, you're currently on a Work/School account type and need to switch.
Switch to Personal (if needed) and connect
Use the link to switch your account type to Personal. You can keep your existing email address — only the account type changes.
Go to your Connectors page, find Bing Ads, and click Connect to Polar Analytics, ideally from an incognito/private window to avoid a cached session getting in the way.
Can't switch your account type (blocked by your organization's Microsoft policy)?
Some organizations' Microsoft Entra/Azure AD policies prevent switching an existing account to Personal. If that's the case, you can set up a separate personal Microsoft identity instead:
Create a personal/private Microsoft account using a personal email address, or convert a work email into one without affecting your existing Microsoft 365 setup by going to signup.live.com, entering your company email, and setting a password. This creates a Personal Microsoft account layered on top of your existing email.
Grant that email Admin access to the Bing Ads account.
Add that same email to Polar as an Admin user.
Log into Polar using that email, then connect Bing Ads as in Step 2 above.
Connecting more than one Bing Ads account? If the second account uses a different login than the first, adding it from your current Polar login usually won't work — Polar ties one email to one Bing connection per user. Instead, invite a new user to Polar using the second account's email, give that user Admin permissions, and connect from there.
Once connected, data will be available at the next refresh, and you'll find it on the Acquisition page, Key Indicators, and in your Custom Reports.
Troubleshooting Common Connection Errors
In Polar, integrating Bing Ads data can present a few recurring challenges — most stemming from Microsoft's own account and consent restrictions rather than anything Polar controls. Below are the main causes we see and how to resolve them.
Why does connecting send me to a Microsoft login that rejects my email, or fail after I sign in?
If clicking Connect under Bing Ads sends you to a Microsoft live.com login page that rejects your email, or the connection fails after you sign in, your Microsoft account type is set to Work/School rather than Personal. This trips people up because it's easy to assume the fix is "use a different email" — it isn't. The email can stay the same; only the account type needs to change.
Steps to resolve:
Go to your Microsoft Advertising account settings and find the "Signed in with" section — see the Connecting to Bing Ads steps above for exactly where to look.
Confirm the account type is Personal. If it's showing as Work/School, switch it — you can keep the same email address.
If switching isn't possible due to an org policy, use the personal-identity workaround in the section above instead.
Separately, if the email you signed into Polar with doesn't match the email set up in Bing, that mismatch is also worth checking: invite the email used in Bing to your Polar account, give it an Admin role in Polar, then sign into Polar with that email before reconnecting.
My connector was working, then it broke — reconnecting isn't fixing it
This is the most common Bing issue we see after initial setup, and usually isn't the account-type issue at all — it's a stale session or revoked permission.
Steps to resolve:
Clear your browser's cache, or try connecting from a different browser or an incognito/private window.
From the Connectors / Integrations page, use Connect account at the top right rather than just re-authorizing in place.
Confirm the account still has Admin access in Bing Ads and is still added as an Admin in Polar — Bing sometimes revokes access silently if permissions changed on the Microsoft side.
