Hi @Janna Goethel,
Welcome to Microsoft Q&A forum.
Thank you for reaching out. I understand you're experiencing an issue where the "New Teams Meeting" button in Outlook remains disabled, despite having the Teams add-in enabled and being signed in with the same account across Microsoft 365 and Teams.
To assist you better with adding the Calendar tab to your Word ribbon or making edits to highlighted dates on a calendar, I’d like to gather a bit more information:
- What type of Microsoft license are you currently using (e.g., Microsoft 365 Personal, Business Standard, E3, etc.)?
- Is this a personal account (e.g., @hotmail.com, @outlook.com) or a business/work account (e.g., through Microsoft 365 or your organization's domain)? The interface differs between these two types of accounts, so knowing this information will help me support you more effectively.
- Are you referring to a calendar template or add-in that you've inserted into a Word document, or are you trying to integrate Outlook calendar features into Word?
- When you mention “highlighted dates,” are these manually formatted dates in a Word calendar layout, or are they linked to some kind of dynamic calendar data?
- Is your goal to customize the calendar layout (like changing colors, fonts, or adding notes), or to automate updates based on external calendar data?
Once I have these details, I’ll be able to guide you through the steps to either customize your ribbon or edit your calendar effectively.
Thank you for your patience and your understanding.
I'm looking forward to your reply.
