Office 64-bit Integration & Support?

SUGGESTED

What's the latest word on Sage 300 and Office integration?  Today we are running Sage 300 2018 and we are currently limited to Office 2019 32-bit.  We are upgrading to Sage 300 2021 this spring but it doesn't appear that Sage 300 2021 supports 64-bit Office.  Is that right?   

Has there been any discussion about supporting 64-bit Office? or any options for those companies that don't have a choice due to other requirements in their infrastructure?  Maybe workarounds or optional configurations?  

Finally, is Office 365 supported?  We dont use that flavor of Office, but are looking at possibly going that route...
