Good point. Here it is:
Application.RTD.ThrottleInterval=5
Which setting? I don't have this issue, but others might.
Just for my understanding, when using Office365 does your PC simply download the executables from the Office365 server and then all execution processing occurs on your local PC? That would explain a slightly slower startup time, and then everything should run just as fast once the Office365 programs are resident in local PC memory.
Or, do any execution services actually occur on the Office365 server? In this case, performance issues could result from network traffic and server workload.
I took it off clients pcs a few years back, nasty slow web browser server side.
Maybe they've upgraded it to proper office with cloud functionality.
