For more information about how to configure Outlook 2016 with these additional values, see Update allows administrators to set additional default mail and calendar synchronization windows for new Exchange accounts in Outlook 2016. The May 3, 2016, update for Outlook 2016 allows you to set these additional values by using the SyncWindowSettingDays registry data. The Outlook 2016 user interface lets you set the Mail to keep offline setting to the additional values of 3 days, 1 week, and 2 weeks. Older items in shared mailboxes and public folder favorites that are stored on the server are not returned in the search results.

Also, when you search in shared mailboxes and public folder favorites that are affected by the Mail to keep offline setting, only items that are cached on your local computer are returned in the search results. Unlike the folders your own mailbox, shared mailboxes and public folder favorites that are affected by the Mail to keep offline setting do not provide a link to view more items from the server that is running Exchange Server.

For example, if you set this value to 1 (one) month, the message displays Currently displaying all messages newer than 1 month, as shown in the following screenshot.Īlso, when you search in a shared mailbox or public folder favorite, older items are missing from the search results. The number of days, weeks, or months that is displayed in the message depends on what you have configured for the Mail to keep offline setting in Outlook.
