Some settings I’ve found useful
| Org DB setting | Effect | Link to documentation |
|---|---|---|
| AutoTrackSentFolderItems | Governs whether emails sent out by Dynamics App for Outlook users are tracked in Dynamics/Power Apps when using mailbox integration. | |
| CreateQueueItemsForAcceptingQueueRecipients | Governs whether a queue items is automatically created for queues accepting items e.g. if you have a queue used to integrate a mailbox. |
