Problems adding and configuring additional Office 365 Outlook activities in Fabric Pipeline

HI Ste15ton ,

Thank you for reaching out to the Microsoft Community Forum.

Please follow below steps.

1. Please sign out of Fabric and Clear your browser cache or open an Incognito/private window. In Windows Credential Manager, remove any stored “Microsoft Fabric” or “Microsoft Outlook Connector” credentials.

2. Sign in to Fabric in the browser with your work M365 account. In Azure portal, go to Azure Active Directory --> Enterprise applications, find “Microsoft Outlook Connector,” and check it’s been granted admin consent.

3. In a new pipeline, don’t copy the Outlook activity, add it from the Activities pane. click Settings --> Sign in. If you still see no pop-up, Disable pop-up blockers/extensions or try another browser. Then click Sign in again. Save & reopen workaround. If the dialog only appears after saving the pipeline and reopening, follow the temporary workaround until the issue is fixed.

Please refer below community threads.
