Outlook Group Calendar - sync issues

[u/teachingfirsties]

Our work calendar has always been able to sync to our iPhone calendar app, Google calendar, etc. this year when it was created, someone chose to create it as a Group Calendar which is different than how it had been done in the past. Now, the only way we have found to sync our personal calendars with the work calendar is to have everything sync to Outlook, which none of us prefer. Does anyone know a way to make this work other than having to use Outlook as the platform for everything? It’s causing us to miss appointments and double book having to check 2 calendar apps and the Outlook one is really not good. We have reached out to the person who keeps the calendar and they prefer it to be listed under group, so asking them to move it out of a group is not an option.
