How to check if Outlook is using Cached Exchange Mode for a remote user that i do not have access to his computer

Hello Experts,

One of my users in Dallas is running into some email client issues, I wonder how we can identify if he is using outlook in cached mode or not?

Please, be aware that I have no access to the user's computer, it has to be done remotely from PowerShell or any other approach

Ideas?

Exchange 2013 SP1, Windows 7 client, office 2013

Ask the user to disable the network so he has no internet connection, then start outlook. If he is using cached mode he will see the contents of his mailbox. If not he shouldn't see anything except maybe archived mail.

Browse to the machine's file system, via the administrative share and check for the existence of a .OST file.

Easiest way is probably to map a drive, so from a command prompt, "Net use z: \\remotecomp\c$"
That will map the remote machines drive as Z:. From there, take a look at Z:\users\USERNAME\appdata\local\microsoft\outlook If there is a big .OST file there, with a recent modified date, then the user is in cached mode.

It is possible, but unlikely that user has moved the .OST elsewhere.

"be aware that I have no access to the user's computer" and "has to be done remotely" are an apparent contradiction. You do not want to have to have the user doing something (complex), I suppose, and you do not have any connection to the user's machine? Starting from there, providing a script that runs on the machine (e.g. by being downloaded from a website) is ok? Note that sending a script or executable via email will not work because of the security features preventing "dangerous" content to be displayed or executed in Outlook.
