Use offline folders with your Exchange account Offline folders make it possible to work with the contents of an Exchange folder while you are offline, that is, not connected to the network. The next time that you establish a connection to the server running Exchange, the offline folders are synchronized.
Offline folders are stored in your Offline Folder file (.ost), which is different from a Personal Folders file (.pst). The.ost file starts as a mirror image of your folders on the server running Exchange.
Any changes made on the server running Exchange or on your computer while you are offline are synchronized when a connection becomes available. A.pst file, by contrast, is just a storage location on your hard disk drive. Changes to a.pst file are not synchronized back to the server running Exchange.
When you are working offline, you work with the contents of an offline folder exactly as you do with a folder that is on the server running Exchange. For example, you can change and move items in your offline Inbox and send messages that are placed in your offline Outbox.
You continue to receive new messages in your mailbox on the server running Exchange. However, you will not be aware of these changes on the server until you connect to the network. When you need to update the contents of the offline folder, you synchronize the folder with the server and then continue to work offline. The Send/Receive command connects to the server, copies the changes that were made, and then disconnects. Any item that you delete from either the offline folder or the corresponding server folder is deleted from both folders when synchronization occurs. Note: If you are using Cached Exchange Mode, you are always working with an.ost file even when you have an active connection with the server running Exchange.
Cached Exchange Mode allows you to work uninterrupted if your server connection is lost or if a network connection is not available. The procedures that follow in this section are not applicable to your configuration.
For more information about Cached Exchange Mode, see the section of this article or the See Also section. On the File menu, click Work Offline.

Note: Beginning with Microsoft Office Outlook 2003, a new Offline Folder file format was introduced that offers greater storage capacity for items and folders and supports multilingual Unicode data. A file that is created in this format is not compatible with earlier versions of Outlook and cannot be opened in an earlier version of Outlook.
Outlook automatically determines the format in which the Offline Folder file is created, based on the version of Microsoft Exchange, the administrator settings, and the formats of the data files that are configured for the profile. If the settings do not allow the file to be created in the new format, Outlook creates the file in the format that is compatible with earlier versions of Outlook that do not support Unicode and that offer the same storage capacity that was available in earlier versions of Outlook.

So, we're running an Exchange 2013 infrastructure, Office 2016 professional plus. I have one user who is chronically complaining about Outlook going offline. It seems to do it regularly, and you can bring it back by clicking 'work offline' to bring it back into online mode. I've done some research, but every topic I can find relates to having another email address set up, such as gmail - that isn't the case here; the Exchange account is the only account in Outlook, and Outlook is running in a VM that's in the same data center as Exchange (we run a VDI environment).
Any idea what could be causing this issue??? Lucid Flyer wrote: Are you able to recreate the same behavior on a physical workstation? How big user's mailbox? Is there enough disk space on the VDI workstation?
Have you tried recreating the user's profile? If it's a static VM. It's just one user. All have the same VDI image; it's a pooled Desktop. I've completely blown the user profile away and re-created it.
I don't have an answer at all, as it's only one user out of 150.Have you ran a recent scan for infections. That's the only thing I can think of that would possibly effect connectivity if it is just one machine. Zuphzuph wrote:Have you ran a recent scan for infections. That's the only thing I can think of that would possibly effect connectivity if it is just one machine. Nothing to scan - Desktops are pooled and recycled to the base image every time a user logs off. The only thing that's saved is user data (Documents, Desktop, etc) - however, this does give me an idea. Part of the saved profile data is Application Data that contains some outlook info - that doesn't get wiped when the profile is wiped.
Perhaps deleting the outlook account and then wiping that folder will help. I'll keep you updated.
