Outlook 2016 oab not updating in cached mode
Note for Mac Users: Mac versions of Outlook do not connect to the Exchange server in the same way as PC versions.Every time a Mac checks for new mail, it also updates the GAL.Again this can be performed with a single Power Shell command in many cases.Alternatively you can assign the OAB to a database using the Exchange Management Console by opening the mailbox database properties and selecting the Client Settings tab.Knowing why the delay occurs means you won’t spend time troubleshooting it.For Users where Outlook is in Cache mode, They got to have their Outlook Address book when they are offline.
To avoid mailbox users on the other four databases re-downloading the entire OAB we can assign an OAB to the databases.
Any mailbox users who do not have an existing OAB assigned to their mailbox directly, or to the mailbox database that they are located on, will download the entire OAB from the new default OAB that Exchange 2013 creates.
In organizations with a large OAB or distributed network environment this is obviously not ideal.
Therefore, there is no need for equivalent instructions for the Mac operating system.
If you're having issues with your Outlook address book, such as a new employee's information not showing up, there may be a simple solution.
