Hi @Merritt Castello ,
In order to verify, do you mean the Microsoft account's calendar or the default calendar in the laptop? And what kind of account are you using in the Windows Calendar application?
- If it is a Microsoft account's calendar, you can use the export and import feature in Outlook. For the detailed steps, please see: Merge items from multiple calendars
- To merge your AOL calendar or other online calendar into Outlook calendar, you can use the Internet Calendar Subscriptions (ICS) feature in Outlook. You’ll need to find the iCal format URL in your AOL calendar.
Then open your Outlook calendar, select Add > From Internet.
Paste the URL from your internet calendar and select OK.
