Hi @Jaudah ,
Thank you for posting your question in the Microsoft Q&A forum.
Based on the information you have provided, it looks like your Outlook calendar is not syncing with Teams.
As you said, you are using Microsoft Office Standard 2016. Unfortunately, this plan doesn’t support Microsoft Exchange Online, which means your Outlook calendar cannot be synced with your Teams account.
You can consider upgrading to more advance plans that support Exchange Online.
