Outlook access shared inbox sub-folder - vba

Question

I have a strange issue on the below code I use for extracting Outlook email information into Excel. Sometimes the code works perfectly but other times I get the Run-Time Error '-2147221233 (8004010f)'. When I do get this error it is the line Set objFolder = objMailbox.Folders("Inbox").Folders("ARCHIVE") that has the issue.
I am running the code on a shared inbox and I have the "ARCHIVE" folder as a sub-folder of the inbox. It is as if the code cannot find the folder even though it is there and it can find it sometimes.
My uneducated guess is that, since a shared inbox can have a delay updating across all users, if there is any action in the folder the code cannot recognize the folder until it refreshes or updates on the server.
Can anybody suggest slightly different code so that it will run every time? Or does anybody have an explanation as to why it only occasionally works as is?

I am assuming you are running the code from Outlook, see the cleanup I did.

ReDim varOutput(1 To SubFolder.Items.Count, 1 To 10)
