pagination and preview

[GtrPksRnt4eatin]

Hey, Thanks for your help the other day,
I have an email box full of log files that are auto-sent daily as attachments.
I need to periodically check through the entire inbox and cross-reference the attachment file names with the data stored in the DB.

The problem that I have is that there does not seem to be a way to "peek" at items without downloading them entirely, and also there does not seem to be any pagination handling.

The peek function may be a limitation of the API, but i figured I'd ask because I was curious.

The pagination could be implemented though because when a request asks for too many items it sends a response with an error code and tells you to use pagination.
I have handled it for now by rescuing the exception and iterating through the mailbox by week until everything is downloaded

It would be amazing to have a peek method where i could retrieve the file names of the attachments before deciding if I wanted to download them..

No rush or pressure here, just trying to get my thoughts down and bounce ideas off the group..

sorry, i am looking through some of the other posts and realizing that the pagination issue is already under discussion, but any insight on peek would be welcome..

Hey guys,

I don't know if you still looking for paging the folder items, but actually this is already supported by the current code, but this feature isn't so clear to figure out.

Looking to the actual code and after take a look at the exchange EWS documentation for paging (here: http://msdn.microsoft.com/en-us/library/office/dn592093(v=exchg.150).aspx), here is how to add paging to folder items:

inbox.messages(
     indexed_page_item_view: { 'MaxEntriesReturned' => 10,
                               'Offset' => 0,
                               'BasePoint' => 'End' })

In my forked repo, I added a method to GenericFolder type to make this easier and also added instructions on the README.md. I'll create a PR with this soon.
