Calendar widget / app with keyword filters + Outlook integration

I'm looking for a calendar / agenda widget that allows for keyword filters, and has Outlook integration.

Reason: My work calendar has people posting (usually) all day events when they'll be OOO, on PTO, on Maternity leave, etc. I can't block every all day event from displaying, because I need to see some of them.

I've downloaded and tried pretty much every calendar app and widget in the play store, and currently the only calendar widget I can find that allows for keyword filters is Todo Agenda ( https://play.google.com/store/apps/details?id=org.andstatus.todoagenda ). I use it, but the widget doesn't update properly much of the time, and there's no outlook integration.

So far as a workaround, I've shared my outlook calendar with my gmail, but updates don't seem to happen with any real frequency, so I'd like to directly connect if possible.

Are there any calendar apps that have both features that I want?
