I'm hoping my title describes my question correctly, below is what I'm trying to accomplish (I've spend hours searching for a solution.)
Create a vacation calendar that is viewable by users in both their Outlook and on the SharePoint Team site calendar. Users should be able to see all others users calendar entries (who's in and out of office.) Our users have to create "out of office" dates in their Outlook calendars, if they have to go to another calendar to enter out of office, I know they won't use it. So I thought if I created a "shared calendar" they could invite when they create the "out of office" entry in Outlook, they'd remember to use the vaca calendar. Then if there was a way to sync the Shared Calendar with SharePoint, my problem would be solved (they would see the Shared Calendar in Outlook.) I know it's not possible to send email to a calendar in SharePoint 365. I found a utility to sync email with SharePoint, but not the calendar. Users Outlook is either 2010 or 2013.
Sorry if this doesn't make sense, I can provide more detail, please ask.
