Ex2010 Hybrid to O365 mail flow delay

Hi,
Recently migrate the exchange to office 356. Unfortunately we are facing mail flow delay issue from on-premise ex2003 to Hybrid server ex2010. So I disabled 2 settings to make the mail flow from ex2003 to 2010. (Tarpitting and MaxAcknowledgementDelay).
Now the problem come, after disable this 2 settings. The mail flow now stuck at hybrid 2010 to o365. Anyone facing the same issue?
Regards,
Wayne

External mail flow delay

I have checked the event viewer nothing related their, also I ran the Mail flow troubleshooter for delays and nothing their as well!
I checked the mail queue and found several messages with the following error (Last Error: 400 4.4.7 Message delayed)
What could be the problem
Thank you

Exchange 2013 upgrade from 2010 and no mail flow and cannot move mailboxes

I am in the process of moving to Ex 2013 from 2010. I have installed Ex 2013 SP1 on a new server 2012 R2. All of my Ex 2010 servers are SP3 RU 5. Ex 2013 is running and I can connect through the EAC and see all other Exchange servers and connectors that
were already in existence. Several puzzling things are happening now that the servers are in coexistence:
1) As soon as Ex 2013 was installed on the network, many Outlook users are continuously being prompted to enter their domain credentials. They can cancel the prompt and Outlook still sends/receives email. No user mailboxes are on Ex 2013 yet.
Why is this happening?
2) I am following the Ex 2013 Deployment Assistant and I get to the step to move the Ex 2010 Arbitration mailbox to Ex 2013 and the move does not happen--it just says "syncing" and never completes. I tried moving a test mailbox from Ex 2010
to the 2013 database and I get the same result. I created the move request on the Ex2013 server and I see it as queued on the Ex2010 server, so I know they are "talking" to each other. However, when reviewing the status of the move I
see "MapiExceptionNoAccess: Unable to open message store".
3) There seems to be no mail flow on the same Ex2013 server or between the Ex 2010 and 2013 servers. I created two new test user mailboxes in Ex 2013. The Ex2013 mailboxes cannot send/receive to each other or to Ex 2010 users. This
seems strange, unless I am completely missing something in the Ex 2013 install?
I know this is a lot in one post, but following the Deployment assistant, I was hoping this would be something that others have faced. Thanks for any input here.

Does the below points already fit for you.
Exchange 2013 Supported with the following minimum versions of Exchange:
1) Exchange*** 2010 SP3 on all Exchange 2010 servers in the organization, including Edge Transport servers.
2) Exchange 2013 CU2 or later on all Exchange 2013 servers in the organization.
*** If you want to create an EdgeSync Subscription between an Exchange 2010 Hub Transport server and an Exchange 2013 SP1 Edge Transport
server, you need to install Exchange 2010 SP3 Update Rollup 5 or later on the Exchange 2010 Hub Transport server.

Exchange Server 2003/2010 Coexistence Mail-flow Issues

I've installed Exchange 2010 in a 2003 coexistence scenario.
2010 was deployed with CAS,HUB, and Mailbox roles.
The installation went through smoothly, and the default RGC was created.
On the 2010 Server, when I create a new users with mailbox, that user is no able to send or receive mail from anywhere.
2010 user to 2010 user does not work
2003 user to 2010 user does not work
Mail delivery between 2003 users works fine.
The RGC message queue in ESM 2003 shows that the messages are queued and keep retrying.
I have deleted the RGC twice and created new ones, I have un-installed the HUB and CAS roles and re-installed them, and I have also re-run setup /preparead and setup /preparelegacyexchangepermissions
I'm not able to make any sense of the message tracking on the 2010 side. It just shows a bunch of entries:
EventID: NOTIFYMAPI
Source: STOREDRIV
When I use the best practices analyzer to test mailflow to a 2010 user from the outside, the test comes back with a pass even though the message itself isn't delivered to the specified mailbox.
There is no smart host defined on the default SMTP virtual server on 2003.
There is no SMTP Send Connector for External or Internal mail configured on 2003 besides the 2010 RGC
Any ideas?

No duplicate security groups. I did notice Exchange 2010 is not in the Exchange Domain Servers group, but 2k3 is. Not sure if that matters.

As long as you cannot send email between ex2010 users this has nothing to do with connectors/smtp config..
I had the same issue one year ago and solved adding both sevrers to old/new exchange sevrers security groups.
Looks like for some missing security entry (not sure why) mailbox is unable to conact HUB  (MSExchangeMailSubmission) I expect you seing items stuck in draft for owa (outbok for outlook)
I saw in some blogs similar cases solved by setting static DNS servers for HUB severs config.
Yes that is similar to what I'm experiencing.
When using the Outlook client with a 2010 mailbox the mail leaves the outbox fine. When using OWA new messages just get saved as drafts when I try to send them.
I will try your suggestions. I see two groups. Exchange Domain Servers, and Exchange Enterprise Servers of which Exchange Domain Servers is a member.

Disaster Recovery: Active/Passive Mail Flow

Hello. I am planning to deploy an active/passive server environment for Exchange 2013. Here's what I plan to achieve:
EXCHANGE-A - on production site, active (all mail flow goes through here), member of DAG
EXCHANGE-B - on disaster recovery site, passive (mail flow goes through here ONLY when activated), member of DAG
I have tried disabling all receive connectors on EXCHANGE-B, however that causes OWA to delay sending messages for around 20 seconds (messages stuck in Drafts folder before being sent out). I have also tried disabling Exchange Transport services on EXCHANGE-B
but to no avail.
Is it possible to achieve active/passive mail flow server environment? What is the best way to achieve this? I appreciate any leads on this matter.

Hi ,
Shadow redundancy configuration is available on the transport config and any change applied on the transport config parameters will get applied to all the transport servers in our organisation and it not specific to the server level.
Command
to disable the shadow redundancy feature :-
set-TransportConfig -shadowredundancyenabled $false
Note : Above command will disable the shadow redundancy feature for your entire organisation.

Approach for O365 mails (pros and cons of both)

Hi Team - What is the right approach to access seamless, flawless emails of O365 in our laptops having Mavericks OS and MailMail . Is Office 2011 for MAC the right choice or should we stick to native MailMail for O365 mails (pros and cons of both).
We attempted with native messaging client but are facing lots of issues related to synchronization, delay, missouts etc... & we are not sure if we shift our users to Office 2011 for MAC, that will fix up the issues.
Please advise..
Best regards,

Database Register in two way :
1.) Static Instance Registration
2.) Dynamic Instance Registration
** Static Instance Registration:
add the entries in $ORACLE_HOME\NETWORK\ADMIN\listener.ora file or by using the GUI
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xx.xx.xx.xx)(PORT = 1521))
)When you check Listener status --> unknown because no mechanism to guarantee that the specified status even exists.
**Dynamic Instance Registration
or service registration , registration is performed by the PMON process an instance background process of each database and doesn't need any configuration in the listener.ora

Migrate Exchange 2010 to 2013 External Mail Flow

Dear All,
I am in the middle of Exchange Server 2010 to 2013 Migration. The scenario is I have single Exchange 2010 server with HUB/CAS/Mailbox and installed new Exchange 2013 with single CAS and single Mailbox server. The internal email flow between Exchange
2010 to 2013 and 2013 to 2010 is working. Having some issues and need assistance to resolve at earliest.
The issue with the external mail flow and I want to Exchange 2010 should be configured to send external email while migrating users to Exchange 2013. Once migrate all users to Exchange 2013 then will configure Exchange 2013 send connector.
How can I configure single name space of web URL for OWA both on Exchange 2010 to Exchange 2013, if user mailbox is in Exchange 2010 can access same OWA URL as user migrate to Exchange 2013.
How to configure SSL certificate, I have single URL certificate this would be enough for OWA, ActiveSync and Anywhere.
Is that possible if directly move the Exchange 2010 database to Exchange 2013 database, this will move all users mailboxes in one go or do I need to migrate users mailbox individual or in bulk.
Kindly guide if any thing missing that need to address during start the migration activity.
Thanks in Advance

Hi ,
Sorry for delay.
Question : Thanks for your valuable response. On
point no.2, I want to use same external URL for Exchange 2010 and Exchange 2013, is this possible if user is on exchange 2010 server or migrated on Exchange 2013 can use same external single name space URL to access OWA ?
Yes you can have the same External URL for the exchange 2010 owa and exchange 2013 owa.So users from exchange
2010 and exchange 2013 can access owa on the same URL from external world.For exchange 2010 users owa connections will be proxied from exchange 2013 to exchange 2010.
For mailbox connectivity issue in exchange 2013 :
1.From internal outlook clients ,Please check the internal outlook anywhere name is resolved to exchange
2013 server and also make sure the authentication set on the outlook anywhere is set to NTLM. Same time we need to have the internal outlook anywhere name on the SAN certificate.
2.Make sure the names used exchange on 2013 URL'S is available on the SAN certificate and also the certificate
needs to installed on the exchange server and that certificate has to be enabled for the required services like iis,pop.imap,smtp.
3.Make sure the outlook client request coming for internal outlook anywhere name and also to autodiscover
service is not reaching the proxy server if you have on your network.
In case if you have proxy server in your environment for internet access ,So for that we need to add the internal outlook anywhere name and autodiscover name
on the internet explorer proxy exceptions for all the internal outlook clients.We can globally achieve it through group policy.
4.please share me the output for the below mentioned command.
get-ClientAccessServer -Identity “server name” | fl AutodiscoverServiceInternalURI
5.If you are having outlook 2007 then make sure it fully patched with latest sp and updates.
6.On which operating system version those outlook 2007 clients are installed?
Please reply me if anything is unclear.
Thanks & Regards S.Nithyanandham

Establish mail flow from Exchange 2007 to Exchange 2013

I am currently using Exchange 2007 into three sites in three cities and two of the sites are connected to Internet sending and receiving emails via Edge transport servers.
Now I am planning to upgrade to exchange 2013 CU1. I don't find any documentation on how to establish mail flow between Exchange 2007 and Exchange 2013. Will it be automatic or do i need to create specific connectors between them?

Was this question answered. We're in the same situation now as we're upgrading to Exchange 2013 from 2007. The latest CU certainly helped. Initially the test mailboxes on Exchange 2013 couldn't email each other - This was resolved with CU7 and
using "Custom Settings" - manually entered IPs for DNS in the Exchange Admin Center "DNS Lookups".
Issue at the moment Test mailboxes on Exchange 2013 cannot email mailboxes on 2007 or visa-versa and mail from external sources queues on the 2007 box.
Any assistance will be greatly appreciated.

Iphone mail app regularly requires restart to get mail flowing???

Anyone seeing this issue? Advice re how to fix?
My iphone mail app regularly requires restart to get mail flowing. That is it is running (doesn't crash) but will at time just stop getting email updates. I then have to force close the mail app (i.e. kill it) and then restart it. After restarting it the mail flows again.
Notes:
a) I do connect to Gmail for my mail - I'm using the IMAP facility for gmail currently (i.e. not the "Exchange" method)
b) I do also have the Google "Gmail" app running on my device too
c) on iPhone 3GS, latest version of IOS

I have this same problem too. I have both a hotmail and work Microsoft Exchange account setup on my iPhone and have intermitent issues with both. Sometimes the hotmail push works, but my work email doesn't push, other times it's backwards, and sometimes neither work. I can't figure it out. Usually restarting the app (closing out of the multitasking bar), and/or going into settings and disabling the affected mail account works. And to top it, I have an iPad, I'll hear the mail chime go off on my iPad, expecting it to go off on my phone....and it never does, not until I manually fetch it.
Very frustrating.

Exchange 2010 to Exchange 2013 mail flow?

We are planning to migrate Exchange 2010 to Exchange 2013.
I understand that we need to upgrade the CAS to 2013 for Internet Facing.
What about mail flow. Currently, Internet mail flows to Exchange 2010 (single site). Can I keep it for sometime after introducing 2013 and do the cutover of HUB once all the mailboxes are moved to 2013? Or I have to get the mail flow to 2013 first.
Also, how does HUB 2010 transfer mail or receive mail from 2013? Does it get from the CAS proxy in 2013 or from HUB?
Thanks!!!

Yes, you can. But my preference is to move the mail routing early in the migration, usually even before moving mailboxes, because I believe it reduces the risk of a service interruption.
I believe it goes through the front-end transport on the CAS, since that is the TCP port 25 service.

Exchange 2013 Mail Flow Through VPN

I have 2 Exchange servers in 2 different AD sites. Is it possible to route mail flow between the 2 sites through a VPN tunnel? I want to force mail flow between the 2 servers to route externally through the internet.
Appreciate any feedback.

Hi Chester,
we have a DNS record for mail and this record is pointing to our private IP address of CAS server. Network team has done network configuration for that particular IP to route the traffic through VPN tunnel to the Exchange servers in other site. Another thing
for you to think is Private IP request won't go to internet and will go to DNS server in that site and once the DNS server will resolve that request against IP address the traffic will be routed to that server.
Kindly mark this as answer if found helpful. Thanks.

External Mail Flow not coming into Exchange 2013 Server

We just finished migrating from Exchange 2007 to Exchange 2013 and when I disable a certain receive connector on Exchange 2007 we stop receiving external emails. I have reviewed all of the Exchange 2013 Receive Connectors and everything looks to be fine
but the server does not get mail flow. If anyone could assist with this issue that would be great.
Thanks,
Ryan

Hi,
According to your description, all your inbound mails cannot be received in your Exchange 2013 server after you disable a receive connector in your Exchange 2007 server. If I misunderstand your meaning, please feel free to let me know.
If yes, since your MX record has been configured properly for your Exchange 2013 server, we can begin with checking the A record for the Exchange 2013 server and confirm if all external mails cannot come in your organization. And we can depend on the following
troubleshooting to narrow down the mail flow issue:
1. Check the NDR information if there is NDR.
2. Check Telnet to test the mail flow:

Exchange 2013 SMTP Mail Flow from external domains

I have query related to mail flow for incoming mails from external domains from Internet facing site. There are two sites - Site A & Site B. Both have Exchange 2013 CAS servers in NLB and Exchange 2013 Mailbox in individual DAG - say DAG1 in Site
A and DAG2 in Site B. Site A is Internet facing site and site B is not Internet facing.
An incoming Internet mail meant for recipient in Site B will land in Exchange 2013 CAS server in Site A. This CAS Server in Site A will look for the recipient in local Domain Controller and get to know the mailbox database of this recipient is in DAG2 (
in site B ) Will the FET service in EX2013 CAS in Site A make a SMTP connection with FET service of EX2013 CAS in site B which will then make SMTP connection to EX2013 Mailbox server in Site B which is holding the recipient mailbox Active copy for delivery.
OR
EX2013 CAS will send this mail to Ex2013 Mailbox server in site A and the Hub Transport service running in in site A will then make SMTP connection with EX2013 Mailbox server in Site B which is holding the recipient mailbox Active copy
Need clarification on above
Thanks

i didn't have any success to fix mail flow, any solution?

Hi Alireza
The above tech-net http://social.technet.microsoft.com/wiki/contents/articles/24056.what-the-crash.aspx
will be applicable only if we get these events in the app log 1019,1018,1036,4999
You can check the transport service is running in which service account - Local or network
It should be running in network account by default.
You can run get-transportagent and check if there are any transport agents installed
If you find them then disable all the transport agents that you have installed on the Exchange servers by running disable-transportagents
Disable the antivirus if you have any installed.
