There seems to be a certain amount of application signature bloat for Microsoft services, or perhaps someone can shed some light on the differences between the highlighted applications below:
![OneDrive.jpg OneDrive.jpg](https://community.checkpoint.com/t5/image/serverpage/image-id/20686i07D9E0747E141CD0/image-dimensions/236x334?v=v2)
![Outlook.jpg Outlook.jpg](https://community.checkpoint.com/t5/image/serverpage/image-id/20687i1FB62DB3093D3B1A/image-dimensions/235x234?v=v2)
This has always confused me, but became a problem after a recent lifecycle and upgrade of one of our clusters. Under R80.40, we were allowing Outlook traffic using the application "Microsoft-Outlook-web". After a lifecycle, which included an upgrade to R81.10, Outlook traffic was blocked and was classified by application "Office365-Outlook-web." Why two different applications for what seems to be the same thing? Check Point's documentation on this (e.g. sk110679) is pretty bare and hasn't been updated in almost 2 years. Any other documentation I'm missing?
