   **Can I have domain-joined and non-domain-joined servers in the same sync group?**  
-    Yes. A sync group can contain server endpoints that have different Active Directory memberships, even if they are not domain-joined. Although this configuration technically works, we do not recommend this as a typical configuration because access control lists (ACLs) that are defined for files and folders on one server might not be able to be enforced by other servers in the sync group. For best results, we recommend syncing between servers that are in the same Active Directory forest, between servers that are in different Active Directory forests but have [established trust relationships](storage-files-identity-multiple-forests.md#how-forest-trust-relationships-work), or between servers that aren't in a domain. We recommend that you avoid using a mix of these configurations.

-  **Why are my tiered files not showing thumbnails or previews in Windows Explorer?**  
-    For tiered files, thumbnails and previews won't be visible at your server endpoint. This behavior is expected since the thumbnail cache feature in Windows intentionally skips reading files with the offline attribute. With Cloud Tiering enabled, reading through tiered files would cause them to be downloaded (recalled).

 * <a id="afs-tiered-files-out-of-endpoint"></a>
   **Why do tiered files exist outside of the server endpoint namespace?**  
-    Prior to Azure File Sync agent version 3, Azure File Sync blocked the move of tiered files outside the server endpoint but on the same volume as the server endpoint. Copy operations, moves of non-tiered files, and moves of tiered to other volumes were unaffected. The reason for this behavior was the implicit assumption that File Explorer and other Windows APIs have that move operations on the same volume are (nearly) instantaneous rename operations. This means moves will make File Explorer or other move methods (such as command line or PowerShell) appear unresponsive while Azure File Sync recalls the data from the cloud. Starting with [Azure File Sync agent version 3.0.12.0](../file-sync/file-sync-release-notes.md#supported-versions), Azure File Sync will allow you to move a tiered file outside of the server endpoint. We avoid the negative effects previously mentioned by allowing the tiered file to exist as a tiered file outside of the server endpoint and then recalling the file in the background. This means that moves on the same volume are instantaneous, and we do all the work to recall the file to disk after the move has completed.

After the  storage sync service or storage account is moved, you need to give the Microsoft.StorageSync application access to the storage account (see [Ensure Azure File Sync has access to the storage account](../file-sync/file-sync-troubleshoot-sync-errors.md?tabs=portal1%252cportal#troubleshoot-rbac)).

     As of February 24, 2020, new and existing ACLs tiered by Azure file sync will be persisted in NTFS format, and ACL modifications made directly to the Azure file share will sync to all servers in the sync group. Any changes on ACLs made to Azure Files will sync down via Azure file sync. When copying data to Azure Files, make sure you use a copy tool that supports the necessary "fidelity" to copy attributes, timestamps and ACLs into an Azure file share - either via SMB or REST. When using Azure copy tools, such as AzCopy, it's important to use the latest version. Check the [file copy tools table](storage-files-migration-overview.md#file-copy-tools) to get an overview of Azure copy tools to ensure you can copy all of the important metadata of a file.

 ## Billing and pricing
 
+* <a id="transactions-billing"></a>
+**What are transactions in Azure Files, and how are they billed?**
+    Protocol transactions occur any time a user, application, script, or service interacts with Azure file shares (writing, reading, listing, deleting files, etc.). It's important to remember that some actions that you might perceive as a single operation might actually involve multiple transactions. For standard Azure file shares billed on a pay-as-you-go model, different types of transactions have different prices based on their impact on the file share. Transactions don't affect billing for premium file shares, which are billed using a provisioned model. For more information, see [Understanding billing](understanding-billing.md).
+
 * <a id="share-snapshot-price"></a>
 **How much do share snapshots cost?**  
     Share snapshots are incremental in nature. The base share snapshot is the share itself. All subsequent share snapshots are incremental and store only the difference from the preceding share snapshot. You're billed only for the changed content. If you have a share with 100 GiB of data but only 5 GiB has changed since your last share snapshot, the share snapshot consumes only 5 additional GiB, and you're billed for 105 GiB. For more information about transaction and standard egress charges, see the [Pricing page](https://azure.microsoft.com/pricing/details/storage/files/).
