I have Outlook 2016 installed on my device; in the Outlook client I have 3 mailbox accounts e.g., point at 3 different exchange servers O365.
For one mailbox I would like to take it 'offline' or 'disconnect' it from the mail (exchange) server, i.e., so I can still access the mails locally but not connect it to the server anymore.
Is this possible without exporting and importing "backup" files?
Many thanks …

The Cached Exchange Mode enables you to work with items in your Exchange mailbox even when your network connection is slow or unavailable. Cached Exchange mode makes local copies of most, but possibly not all items. Also, it doesn't take the account offline as desired, and the Work Offline is a global setting that affects every account.
What you probably should do is to export email, contacts, and calendar to an Outlook .pst file.
