I've been trying to retrieve some of my e-mails in order to have them as data in R. In case it is needed, it is on a Microsoft Exchange Server.

require(RDCOMClient)
folderName = 'ElastAlerts'

#creating the outlook object

OutApp <- COMCreate('Outlook.Application')
outlookNameSpace <- OutApp$GetNameSpace("MAPI")

folder <- outlookNameSpace$Folders(1)$Folders(folderName)

But the final line shows me the following error:

<checkErrorInfo> 80020009 
No support for InterfaceSupportsErrorInfo
checkErrorInfo -2147352567
Error: Exception occurred

Thank you.

I was facing the same issue and resolved it after playing around it.

Possible solutions,

In folder <- outlookNameSpace$Folders(1)$Folders(folderName)

This instead of using "1" try using "2" or "3", it works for me.

Don't know why it is changing folder index.

Make sure the specified folder exists in the store.

But the final line shows me the following error:

 folder <- outlookNameSpace$Folders(1)$Folders(folderName)

The specified line of code contains multiple property and method calls. I'd recommend breaking the chain of method calls and declaring a single method call on a separate line of code. That way you will be able to find a method or property which fails.

Note, you can iterate over all folder in the folder and find the required one by using the Name property.
