Unable to add an e-mail address to the distribution group

Hi guys,

I've got Exchange online and I'm trying to add an a-mail address to the restriction list in one of the distribution groups but unable to do that since it gives me an error message below:

The action 'Set-DistributionGroup', 'AcceptMessagesOnlyFromSendersOrMembers', can't be performed on the object 'Board of Directors' because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.

I'm aware that such changes must be done on premises but I wasn't able to do that in AD as well. Could you please advise what can be done in that case? Thank you in advance.

Mails Are getting stucked into submission queue-Can Not open the mailbox /o=/ou=exchange.......cn-microsoft system attendant

We have suddenly observed that some mails are getting stucked into submission queue.Upon analyzing the sender and recipient of the mails got stucked on the queue we have identified that recipients of those mails are located on a particular exchange database. 

We have observed an error "Can not open the mailbox /o=<orgname>/ou=exchange administrative groups......../cn=microsoft system attendant  while trying to open any of the above mailboxes from ECP console whose mails got stucked in queue.


Not everybody of the same database was having the issue of mail got stucked in queue or "can not open the mailbox....".So it may not be a db level issue.Also some other database mounted on the server was not having the same issue.So this may not be a exchange server level issue.

None of the database are showing dismounted also..All are mounted.

But out of the mails which got stucked in the queue; all the recipient had the "can not open the mailbox.....Microsoft system attendant" error.

I have tried to move the effected mailboxes to some other database but those are not getting moved also. 


What can be the issue...Please advise me....Please let me know in case of anything needed.

Set auto reply for messages, sent to specific accepted domain

Hi,

we have an exchange server 2013, which handles the messages for two accepted domains, let's call them domain1.com and domain2.com. This occurred after the acquisition of another company, which domain is domain2.com. I want to set an auto reply message for all recipients, so that when an external sender sends messages to @domain1.com an auto reply message to inform the sender, that after three months the domain @domain1.com will be no longer available and all the messages, sent after this period must be send only to @domain2.com. I have tried to do this via transport rule, but I did not find where to put the text on "Actions" step. Does anybody know to complete this scenario? Just to mention that setting up an Outlook rule is not an option, because it is mandatory auto reply messages to be sent even if Outlook is not started.

Thanks in advance.

Hello.

I deployed a test environment in lab with 3 vm computers. One is for AD server whose ip equals "10.204.166.43".  the second is an exchange 2016 server, and its ip is "10.204.166.34". The third is a test client computer which ip is"10.204.166.44". The dns server is all "10.204.166.43".

User test003(test003@zack.test) can send email to test004(test004@zack.test), and the email is shown in "Sent Items". But user test004 cannot see the email.

With Get-MessageTrackingLog shell command, I got log information like "EventId:FAIL, Source:SMTP, MessageSubject: Undeliverable".

May someone help me?

Thanks a log!

Problem relaying to one of our domain after changing public IP.

After changing our public IP we are having problem relaying to one of our domains. Our on-prem exchangeserver (used only for relay) get the following error in the message queue.  

"Last Error: 451 4.7.500 Server busy. Please try again later from [x.x.x.x]. (AS77713200) [HE1EUR04FT016.eop-eur04.prod.protection.outlook.com]". 

It's a scanner that have worked fine prior to the change of public IP change but now all mails from this scanner now gets stuck at  our on-prem Exchange server. Outlook klients have no problem and scanners that send mail to our other domains.

- We have updated our SPF records for all domains.

- Tried to create a IP whitelisting in O365 when sending from the relayserver.

Hi we have problems with Out of office and DMARC, the return-path is empty so the out of office message going straight into the spam/junk folder of hotmail/gmail etc.

I have googled for a solution to this issue, but just found that people solve the problem with third party software / appliances.

Anyone had the same problem and found a solution?

Email Jam in the Journaling Queue

We have random emails mostly, it looks like just spam that keep getting jammed up in the "Journaling Queue" with the following error;

“Last Error: 400 4.4.7 The server responded with: 550 5.6.2 SMTPSEND.BareLinefeedsAreIllegal; message contains bare linefeeds, which cannot be sent via DATA. The failure was replaced by a retry response because the message was marked for retry if rejected.”

I have followed the "Bare linefeeds clogged" question earlier and I'm continuing to get these messages on a daily basis even after changing the BareLinefeedRejectionEnabled to $true.  These were the connectors that I updated (which are all of them)

  • FrontendTransport
    Set-ReceiveConnector "FSRM-SMTP" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "SERVERNAME\Client Frontend SERVERNAME" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector -Identity "SERVERNAME\Default Frontend SERVERNAME" -BareLinefeedRejectionEnabled $true
  • HubTransport
    Set-ReceiveConnector "Client Proxy SERVERNAME" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "Internal-Relay" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "SERVERNAME\Default SERVERNAME" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "Outbound Proxy Frontend SERVERNAME" -BareLinefeedRejectionEnabled $true

I have to manually "Remove (without sending NDR)" and I would like to find a resolution so I don't need to monitor and worry that emails are jamming up in this queue anymore.  Any ideas?

Mails being refused by Gmail due ti ipv6 in mailheader

Hi

Gmail is rejecting mails because of ipv6 information in the mail header (exchange 2013). I have read some threads saying that I could do a reghack do disable ipv6. But I have also read that Exchange 2013 depends on IPv6 - so disabling IPv6 could cause other problems in mail routing. I have reverse PTR on ip4. I dont have the option to create SPF records.

So what can I do to prevent Exchange 2013 from adding IPV6 info to the mail header?

Internal CAS Servers servicing clients despite being behind a Load Balancer

October 4, 2018, 9:05 pm

Hi Everyone,

We have 10 CAS servers, with the OA and Autodiscover URL going via a load balancer, which redirects to the 10 CAS servers.

We recently put in an additional two CAS servers, and set the relevant URLs to go via the Load Balancer. We intentionally didn't add these CAS servers to the load balancers to avoid connections at this time while we perform some additional work.

However, it appears that internal Outlook clients are picking up the new CAS server despite picking up the LB URLs. The external clients, which cannot use SCP, do not use the new CAS servers.

I'm not understanding how this is possible? I was of the impression that Outlook retrieves the SCP record, which points to the LB URL, and then it should go to the designated CAS servers.

Can anyone shed some light on why this might be occurring? With the SCP records, does it pass the connection off to a local site CAS server despite the LB by design? 

Cheers!

Hi

I've a problem with connection to Exchange 2016 when users are outsite. Inside company (LAN connection) when users run outlook 2010 or 2013, there is no problem with connection to server. When they are outside and run Outlook they gets password prompt window. If they fill in password, the conection is established. Users have to change password for every 30 days so they can't use option "Rememner password".

What is the problem? Please help.

SMTP relay to Exchange Online

October 9, 2018, 12:06 am

Hello TechNet,

We have 4 Exchange 2013 servers configured in hybrid mode with Exchange Online. All mailboxes have been migrated to the online service and the MX records points to Exchange Online.

The purpose of the on-prem servers is for management and SMTP relay for printers and applications.

When we send e-mails to distribution groups that are not synchronized from AD or public folders that wasn't migrated (they were created in Exchange Online) via the SMTP service on-prem, they get discarded with a 550 5.1.1 RESOLVER.ADR.RecipNotFound message.

I suspsect that this is related to how accepted domains and send connectors are configured in Exchange 2013, and I would be very grateful to get some input on how to configure this correctly for our scenario.

- Our default mail domain (xxx.com (no not actually)) is configured as "Authoritative" on-prem, and as "Internal Relay" in Exchange Online.
- The scope of our send connector "Outbound to Office 365" only contains "xxx.mail.onmicrosoft.com".

What I would like to do is to re-configure our default domain to "Internal Relay" and add xxx.com to the scope of the Office 365 send connector.

My concerns are that this will break mail flow in any way or that it may cause an e-mail loop when sending to non-existing addresses.

Any input on this matter is greatly appreciated.

mail flow delays

i have a few emails being delayed from an external sender (only that i know of but could be others).

it hits my mail MTA at 9:02.

immediately i see a return message in the MTA logs from my load balncer VIP IP sayin DSN 4.0.0. message deffered

at 9:21 is see the message queued message in my MTA logs

on the exchange 2013 server, message tracking logs show the message was received at 9:21 and then delivered. i dont see any mails with defer status or any other eventIDs for the delivery of the mails apart form standard ones.

any ideas on where i can look. most external domains can deliver with no delays. this message did have a attachment., but i presume the AV scanning in 2013 is done in the transport pipe line so a delay would should up in message tracking.

Reconfiguring SPF record for more than 13 cloud email sending service provider?

I need some help in reconfiguring the SPF record issue in my currentdomain.com like below:

v=spf1 include:mailgun.org include:sendgrid.net include:amazonses.com include:surveymonkey.com include:spf.protection.outlook.com include:servers.mcsv.net include:mailcontrol.com include:modulargateway.com include:cloudservice.com ip4:202.89.252.19 -all

When using this service: https://dmarcian.com/spf-survey/

I can see the result is:Error: Too many DNS-querying mechanisms (count=13)
13 / 10 DNS-querying mechanisms/modifiers to resolve the record
72 netblocks are authorized
804,283 individual IPv4 addresses

So how to fix this issue to allow my email domain.com to send out the emails with no problem of being blocked by the other client/receiver antispam engine?

The Marketing team wants to use Reply-To Shared mailbox as MKT.Team@domain.com --> Using MCSV
The Product-A team wants to use Reply-To Shared mailbox as Product-A@domain.com --> Using MailChimp
The product-b team wants to use Reply-To Shared mailbox as Product-B@domain.com --> Using Amazon AWS (SES)
....
The product-z team wants to use Reply-To Shared mailbox as Product-Z@domain.com --> Using 3rd party senders....

Thanks in advance.

We are facing problem of blocking Embedded Images, we have changed the image type from jpg to png and disable the attachment filter on edge server but Embedded Images are still blocking on user end (outlook & OWA). When we sent an email to gmail it's working fine but when send to inside of organization the embedded image have destroyed. we are using an application that needs to send an email to outside and inside with embedded image through SMTP settings and we are using CAS server as a SMTP for sending email from application.  Please suggest workaround to cater this problem.
