Why did Office 365 Connectors retire?

Microsoft retired Office 365 Connectors due to security, scalability, and flexibility concerns. The retirement date was March 31, 2026.

What's the easiest replacement for the GitHub Office 365 Connector?

For GitHub PR notifications specifically, PullNotifier is purpose-built. Power Automate is Microsoft's general-purpose recommendation but requires manual Flow building per repo.

Will my old MessageCards still work?

No — connector-based MessageCards stopped delivering on March 31, 2026. PullNotifier sends modern Adaptive Cards.

How long does the migration take?

About 5 minutes total for most teams. Install PullNotifier, sign in with GitHub, recreate channel mappings, then disable the old connector.

Is the migration covered by a free trial?

Yes — email gabriel@manta.so with subject "O365 migration" for a 90-day extended trial.

Office 365 Connector Replacement

The easiest Office 365 Connector replacement for GitHub teams

Microsoft retired Office 365 Connectors on March 31, 2026, breaking webhook-based GitHub-to-Teams notifications. PullNotifier is the 5-minute migration path — no Power Automate Flows.

Why teams switch from Office 365 Connectors

Office 365 Connectors were retired by Microsoft on March 31, 2026 due to security and scalability concerns. Every webhook-based GitHub-to-Teams setup that used the connector pattern stopped working on that date.

Microsoft recommends Power Automate Workflows as the official replacement. That works — but rebuilding the integration as a Flow takes 30+ minutes per repo, and Flows lack smart filtering, user mapping, and digest features.

PullNotifier is purpose-built as the connector replacement: install once from Microsoft AppSource, sign in with GitHub, point at a Microsoft Teams channel — done. Your team is back to receiving notifications in 5 minutes.

PullNotifier vs Office 365 Connectors

An honest, side-by-side comparison

Feature	PullNotifier	Office 365 Connectors
Status in 2026	Active, GA	Retired March 31, 2026
GitHub PR notifications in Microsoft Teams	Yes	No (broken)
Migration time	5 min	Not applicable
Smart adaptive cards	Modern	Legacy MessageCard
Smart filtering	Built-in	No
Per-channel routing	Yes	One webhook per channel
User mapping	Yes	No
Maintenance	Managed service	Self-managed webhooks

Other options Microsoft recommends

PullNotifier isn't the only path. Microsoft's official recommendations:

• Power Automate Workflows — flexible but Flow-building takes 30+ min per repo. See our /alternatives/power-automate-github page.

• The official @github bot — free but limited (no per-channel routing, user mapping, or digest).

• Custom GitHub Actions YAML — works but every repo needs its own workflow file.

• Third-party tools like Axolo (currently in private early access for Teams).

PullNotifier is the recommended path when migration speed and feature parity with the original connector experience matter. Free tier covers small teams indefinitely.

What PullNotifier does better

5-minute migration vs 30+ min per Flow

Install from AppSource, sign in with GitHub, pick a channel. Power Automate requires building a Flow per repo with triggers and Adaptive Card JSON.

Modern adaptive cards, not legacy MessageCards

Office 365 Connectors used the legacy MessageCard format. PullNotifier uses modern Microsoft Teams Adaptive Cards with action buttons.

Smart filtering out of the box

Connectors fired on every event. PullNotifier filters draft PRs, dependency bumps, and bot PRs by default.
