I've decided to close my Gmail account, and for that purpose I've added my account into Outlook as a Send/Receive account so that I get a backup of all my emails in Outlook. There are thousands of emails, and it will take some time to complete. I was browsing the imported emails in Outlook and noticed a lot of documents and images. I want to have an archive of these documents, and not lose them with closing my account. I wanted to know whether those attachments will also be preserved into my Outlook account or does Outlook fetch them as and when required?

Also, another (unrelated) query. Is there any limit on the total inbox size of Outlook? As far as I know, there isn't one.

Thanks!
