Outlook 2013 introduced the concept of hybrid mode (sometimes called Exchange Fast Access) to allow clients configured in cached Exchange mode to fetch data direct from the server when possible. The mode works well, except when you’re connected on a poor network as the attempts to fetch data from the server might cause Outlook to hang. A registry setting gives a way to force Outlook to operate in classic cached mode and use the OST exclusively when it needs data.
A question about how best to set auto-replies for Exchange Online shared mailboxes to respond to messages arriving during a public holiday gives another chance for PowerShell to show how useful it is. You could do the work with Flow, but PowerShell is more flexible and capable when dealing with multiple shared mailboxes.

This caused problems for users who didn’t receive notifications of new mail. Software can have bugs, but configuration changes should be tested before getting to production.
Microsoft has announced that the switchover to the new OWA interface will start on July 22 when Office 365 tenants in targeted release will lose the chance to toggle back and forth between the two interfaces. By the end of September, everyone will use the new OWA. Let’s hope that Microsoft has fixed all the functionality gaps by then.
