MS POST · Build recall with a focused review session.
34 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Accepted domain types
- Authoritative delivers mail to local mailboxes; Internal Relay forwards unknown recipients through a Send connector; External Relay forwards mail for an external domain that does not exist locally.
- Email address policy priority
- Policies apply in priority order, lowest number first; the last policy applied determines the final primary SMTP address when multiple policies generate the same address type.
- Address book policy
- An ABP assigns a specific global address list, offline address book, room list, and address lists to mailboxes, giving users a scoped view of the organization directory.
- Retention policy tags
- Retention tags define retention or deletion actions for folders or items; a retention policy groups tags and is assigned to a mailbox to enforce them.
- Mailbox quota thresholds
- IssueWarningQuota warns the user; ProhibitSendQuota blocks sending; ProhibitSendReceiveQuota blocks both sending and receiving and returns a mailbox-full NDR.
- Transport pipeline order
- Mail flows through Front End Transport, then the Transport service (Submission, Categorizer, Mailbox Transport Delivery), then the Mailbox Transport service to the mailbox database.
- Send connector selection
- Outbound mail uses the Send connector with the most specific address space match; ties break by lowest cost, then by the most recently modified connector.
- Shadow redundancy
- The Transport service keeps a shadow copy of a message until delivery is confirmed, allowing resubmission if a server fails before the message is delivered.
- Safety Net
- Safety Net stores copies of successfully delivered messages for a configurable period and resubmits them after a mailbox database failover, replacing the transport dumpster.
- Categorizer role
- The Categorizer resolves recipients, expands distribution groups, applies transport rules and journaling, and routes messages to the next hop in the pipeline.
- Transport rule priority
- Rules evaluate in ascending priority order; a StopProcessing action ends evaluation so later rules do not run on that message.
- Message tracking log
- The tracking log records transport events such as RECEIVE, SEND, DELIVER, and FAIL; Get-MessageTrackingLog filters by sender, recipient, and event ID.
- Hybrid Configuration wizard
- The HCW configures federation trust, OAuth, the Intra-Organization connector, and the organization relationship required for coexistence between on-premises Exchange and Exchange Online.
- Hybrid Agent
- The Hybrid Agent uses outbound-only connections from on-premises to Exchange Online, avoiding the need to publish inbound EWS, Autodiscover, and SMTP endpoints.
- Migration batch types
- Cutover moves all mailboxes at once with no coexistence; staged supports coexistence with legacy Exchange; hybrid supports ongoing coexistence with Exchange 2010 and later.
- Migration endpoint
- A migration endpoint stores the connection settings for the source server, including the server name, credentials, and MRSProxy or IMAP port used for the move.
- Remote mailbox object
- After a hybrid move, the on-premises object becomes a mail-enabled user with a targetAddress pointing to the Exchange Online mailbox; Enable-RemoteMailbox creates one.
- OAuth for hybrid free/busy
- Cross-premises free/busy requires an OAuth configuration and the organization relationship created by the HCW, plus the Availability address space for the remote domain.
- Anti-malware agent
- The MalwareFilter agent scans attachments for malware on Mailbox and Edge servers; it can be disabled per server and configured with malware filter policies.
- Anti-spam agents
- Content Filter, Sender Filter, Recipient Filter, Sender ID, and Connection Filter agents run on Edge servers or on Mailbox servers when the anti-spam agents are installed.
- Mailbox audit logging
- Mailbox audit logging records owner, delegate, and administrator access to mailbox items; it is enabled per mailbox or per organization and queried with Search-MailboxAuditLog.
- Management scope
- A management scope restricts a role assignment to specific recipients, servers, or databases, limiting what an administrator or role group can manage.
- S/MIME
- S/MIME uses X.509 certificates to sign and encrypt messages; certificates must be published in Active Directory or exchanged between the sender and recipient.
- Domain Secure
- Domain Secure is mutual TLS between organizations; it requires the remote domain in TLSSendDomainSecureList and a Send connector configured for domain security.
- Moderated recipient
- A moderated recipient routes incoming messages to a moderator for approval; the arbitration mailbox stores the approval request and the moderator's decision.
- Journaling types
- Standard journaling records all messages to and from a mailbox database; premium journaling uses journal rules to target specific recipients and store copies in a journaling mailbox.
- Poison message queue
- The poison message queue holds messages that repeatedly crash the transport service during processing; an administrator must resume or remove them.
- Test-Mailflow cmdlet
- Test-Mailflow sends a test message between mailbox servers and reports latency and success, verifying end-to-end mail flow in the organization.
- Shared mailbox
- A shared mailbox has no separate login; delegates access it with FullAccess and SendAs permissions, and Exchange Online does not require a license for the mailbox itself.
- Resource mailbox booking
- Room and equipment mailboxes use booking policies such as AllowConflicts, BookingWindowInDays, and MaximumDurationInMinutes to control how meetings reserve the resource.
- Dynamic distribution group
- A dynamic distribution group computes membership at query time from a recipient filter or OPATH query; membership is not stored as a static member list.
- SendAs versus SendOnBehalf
- SendAs sends as the mailbox with no sender indication; SendOnBehalf shows both the delegate and the mailbox, and requires the delegate to have the SendOnBehalf permission.
- ActiveSync device access rules
- Device access rules set Allow, Block, or Quarantine per organization, group, or user; quarantined devices remain blocked until an administrator approves them.
- Modern authentication
- Modern authentication uses OAuth 2.0 tokens instead of basic credentials; Exchange Online requires it, and disabling it blocks clients that rely on basic authentication.
