SharePoint Group Calendar Web Part Not Showing Events from Group Calendar in Outlook

[MBUWACR]

I am running into an issue whereby the group calendar events from several months in the future are not showing up in the SharePoint Group Calendar Web Part meanwhile they do show up in the Group Calendar in Outlook. Is there a limitation in what the Group Calendar Web Part's Upcoming Events show based on when the event occurs? (e.g. 4/5 months) since I can see a meeting I have scheduled for the end of March but cannot see one for the end of June?

Hi @MBUWACR,

Group Calendar Web Part only shows upcoming events starting between current time and current time plus six months. So, end of June events are not yet visible.

I have the same issue and it's not showing future or past events.
None of the solutions I've read online worked.
