Steps to Switch from Work Offline to Work Online In this guide, we’ll discuss the steps to change or switch from working offline to working online in Microsoft Outlook and the methods to fix and reconnect an offline Outlook profile or OST file. Users can also choose to work offline using the ‘ Work Offline’ option in Outlook. Users can continue their work in Outlook and perform tasks, such as reply to urgent emails, move emails or other mail items between the folders, or delete items from folders, without experiencing any issues.Īs soon as the system connects to the internet, the changes stored in the OST file are automatically synchronized with the server mailbox on the Exchange server so that both copies are the same. This allows Outlook users to work offline even when the internet is unavailable or slow.
