550 5.7.1 Client does not have permissions to send as this sender

​

POP3 and IMAP
-------------------------
Status: offline Clients like IMAP and POP3 uses the Client <servername> Receive -Connector. In order to allow clients to submit messages via this connector, you need to issue below command: 

get-receieveconnector Client <servername> | add-adpermission -user AU -extendedrights ms-Exch-SMTP-Accept-Authoritative-Domain-Sender 
  
Issue 
=============
RE: 550 5.7.1 Client does not have permissions to send as this sender

Resolution
=============

In adsiedit under :  Configuration - Services - Microsoft Exchange - 
<organization name> - Administrative Groups - Exchange Administrative Group
- Servers - <Servername> - Protocols - SMTP Receive Connectors - Client <servername>

Right click and click properties, click the security tab and grant the Authenticated users group the Accept Authoritative Domain Sender allow permission.

Other settings can be checked is as follows

From EMC 
Get-IMAPsettings 
check  logintype,

We checked the settings on the Outlook and is correct. SPA is unchecked.
In Advanced we have IMAP port as 993- SSL.
In outgoing server we have "use same server as incoming server" checked.

Tested mail flow but incoming IMAP passes the test and Sending mail SMTP fails.

How Mail from outlook sent to another outlook via Exchange server

The Mail Submissions Service on the Exchange 

2010 Mailbox Server notifies the Hub 

Transport Server that a message is in the Outbox. The 

Store Driver on the Hub Transport 

Server retrieves the message from the Mailbox Server. 

RPC is used for communication between the Hub and the 

Mailbox Server.


or 

1. The Microsoft Exchange Mailbox Submission service that's running on Mailbox1 notifies an Exchange 2010 Hub Transport server that's located in the same Active Directory site of the new mail item for transport.
2. Using RPC, the store driver component on an Exchange 2010 Hub Transport server in the same Active Directory site retrieves the message and puts it in the Submission queue on the local server.
3. From the Submission queue, the message moves through categorization. The categorizer first performs recipient resolution and determines that joe@contoso.com is an external recipient.
4. The routing component selects the best connector through which to route the message and calculates the least-cost routing path to that connector. In this example, a Send connector has the address space *.contoso.com and is the connector selected by the routing component. All the source servers for this Send connector are located in Site B.
5. The routing component determines the next hop required to reach a source server for the Send connector. The Hub Transport server in Site A queues the message for SMTP delivery to Site B.
6. If the receiving server in Site B is a source server for the Send connector, it queues the message for delivery to that Send connector. If the receiving server isn't a source server for the *.contoso.com Send connector, the message is relayed by using SMTP to a Hub Transport server in Site B that's the source server for the connector.

Netmon from Command Prompt

Netmon from Command Prompt

Start > Run type CMD click OK. 

cd "c:\Program Files\Microsoft Network Monitor 3"

C:\nmcap.exe /network * /capture /file ExchangeTrace-client.chn:100M 


c:\nmcap.exe /Network * /Capture /CaptureProcesses /File ExchangeTrace.chn:100M

In the below example the client IP is 10.10.50.40 and the server IP is 10.1.75.20

nmcap.exe /Network * /Capture "(ipv4.Address == 10.10.50.40 and ipv4.Address == 10.1.75.20)" /CaptureProcesses /File ExchangeTrace.chn:100M

File share folder is inaccessible from the Exchange server 2010

File share folder is inaccessible from the Exchange server.

We checked and found the folder permission is fine.

We added the "Exchange subtrusted system", still the same issue.

We click the "Share" under "Network file and Folder sharing" (>apply > OK)

Now issue is resolved.

Stateless protocol

In computing, a stateless protocol is a communications protocol that treats each request as an independent transaction that is unrelated to any previous request so that the communication consists of independent pairs of requests and responses.

lossy failover

The default setting is GoodAvailability, which translates to 6 or fewer logs 

BestAvailability (12 or fewer logs missing) and Lossless (0 logs missing).

from 

Host or Local Candidate – The actual IP address bound directly to the remote client’s host operating system.  This could include multiple candidates as the remote host could contain multiple physical or virtual network adapters including any active VPN clients.  Most often this will be a single IP address of the active interface on a Lync client’s workstation.

Reflexive or STUN Candidate – The public IP address assigned to the client’s immediate firewall perform network address translation.  In most home networks this would be the public IP addresses assigned by an ISP (either dynamically or statically) to the premises modem or router, depending on the type of service.

Relay or TURN Candidate – The publically accessible IP address assigned to the media relay server which is allocated to the client.  In Lync Server this is the public IP address assigned either directly to the external A/V Edge interface or the public IP address allocated to a NAT device (e.g. firewall) which is performing static network address translation to a private IP address assigned directly to the Edge Server.  In the event that an Edge Pool is deployed then this would be the IP address of one of the individual servers in the pool.
