Outlook 2016 connected to exchange but not updating


I've got a user who was able to connect to our Exchange 2010 server from their home internet access point without a problem.

He took his laptop to a hotel, and now Outlook won't connect.

The new contents such as emails, contacts, calendar items, tasks, notes and others are not updated and not downloaded even though user manually select “update folder” in order to pull the new data.

But user can login to OWA (Outlook Web Access) or to continue to access the missing email messages, appointments, contacts, tasks, journal entries, notes, posted items, and documents.

In this guide, the relevant timings are explained and instructions are given in how you can directly force an update and resync, which can be very handy when troubleshooting or when you work in an Exchange environment which sees a lot of user mailbox mutations.

This means that in the worst possible scenario, an update to the Address Book won’t become available to the user until 48 hours after the change.

I hope I can get these messages simply by logging on via OWA on my old PC, creating a new folder, moving the Inbox messages into it, then DL'ing via Outlook on my new PC and sorting however I want.
