Upon changing my approach from remoting to the Office 365 server to looking at Exchange functionality, I discovered the EWS Dll.
It appears that one can use that and obtain just about whatever one wants via the web. I’m sure it is throttled, but should work.
Some links I’ve found so far:
Reading headers… this one is just a few inches from what I need, because it already opens the item. Just a matter of looking at the $item.body
Get messages (use with caution – don’t know the site yet)
The trick was discovering that Exchange Office 365 could be accessed with the Microsoft.Exchange.Webservices dll, and then
binging for : “powershell microsoft.exchange.webservices.dll” …
I’ll remember that algorithm in the future, since I’m a C#/>net developer. If searches for what you want to do like “powershell read email” don’t turn up anything, look up how one would do it in C#, and find the object name, and search for that.
I appreciate this community and all your help.
