451 4.7.0 Timeout waiting for client input

From last couple of days i am facing issues in receiving few external emails with delay. We have Exchange Online protection as a gateway and Edge Servers 2010. This is sure that the delay is between EOP and Edge Servers. On further investigation i have enabled verbose logging on my "Receive Connector" from Internet to Edge. There i found an error "451 4.7.0 Timeout waiting for client input" and same is logged in EOP message Trace and message stays there in "Pending" state and Defer. I have googled very much but did not find any reliable solution.

Any help on this forum will be appreciated.

Thanks.

Outlook clients not taking autodiscover settings on server

We're trying to get around the invalid certificate name by assigning our internal autodiscover to what's on our certificate name.  I've set the correct information on our hub transport servers but our Outlook clients are not pulling down the settings. They still see the old internal names when running autoconfiguration in outlook and we're still getting the certificate error because of it.

Does the autodiscover URL need to be anonymous?  If I try to reach the XML autodiscover file in a browser I get a password prompt.

Thanks for your input!

Copy newer .edb-file over existing old

Hello.

We had a server crash (sbs2011), and as usual with our bad luck, the backup is 4 weeks old.

We have access to the crashed servers Exchange files, is it possible to copy them to the 4 week old backup?

And, if users connect to the 4 week old exchange data, will the connection fail? will the emails on the Outlook client get deleted? or will Outlook synch with the 4 week datafiles and update from Client to server?

Best regards

Delay in delivery of email issue Exchange 2010. ERROR: read error: generic::failed_precondition: read error (0): error

Hi,

We are getting reports from some of our users that email from outside are not getting delivered.  We are using Google Apps as our Spam Filter and Exchange 2010.  The email will be attempted to be delivered but eventually will not reach. 

As per Google Apps Spam Filter the email was delivered *but* if I drill down the problematic message in the log, it has an error:"ERROR: read error: generic::failed_precondition: read error (0): error".  I opened a case with Google, they couldn't find anything on their side other than, they attempted to deliver but got no response from our end.  Hence, the message was not delivered.

In other words, it looks like Google Apps try to deliver. But when it tries to reach our Exchange server, it drops connection.

I used Microsoft Connectivity Tool and "sometimes" I get this error message, sometimes I get a complete success.

Please advise how to troubleshoot further. Thank you!

Send as distribution group error

Hello,

I have been troubleshooting a problem whereby a user get's an error stating they do not have permission to send as a particular group if they select that group using Outlook's auto-complete option.  If they select the group manually from the GAL it works fine.  The troubleshooting steps I have tried up to now include;

1. Validating the user has the Send As permission as configured in AD for that group

2. Other users who have the same access do not have the problem

3. Creating a new mail profile

4. Cleared the entry from the auto complete by running outlook /cleanautocompletecache, selecting the entry (which works the first time) and then the second time selecting it from the auto complete - this fails

5. Other groups that the user has permissions to send as work fine

I'm at a loss to figure out the difference between selecting it from the auto complete option and the GAL as the later always works, but the former never works.  

Can anyone suggest any other places I can look to figure out what the problem might be?  The user has Outlook 2010, and our Exchange server is 2010 SP3 with Update roll up 10.

Many thanks

Brian

Question about topology when migrating NLB Unicast for Hardware Load Balancer

November 6, 2015, 7:48 am

In my environment I have 2 DAGs and 2 CAS/Hub servers. All are VMs running  2008 R2, running in a failover cluster.

The 2 CAS/Hub servers are configured as NLB unicast. In this cenario, I'm having a lot of switch flood in my network.

I would like to use a hardware load balancer to load balance the CAS servers, and remove the Nlb.

My main question now is about the topology on the new cenario:

If I create a Virtual Ip (VIP) on my load balancer, and direct users to this VIP, the VIP would forward the packets to a server. But the server will be reply this request directly to my users (because they are in the same network) right? This will drop the connections. See examples below:

Network address:  172.16.0.0/16

User Computers IP: 172.16.10.1/16

VIP: 172.16.1.200/16

Server IP: 172.16.1.100/16

How this cenario would work?

Exchange Management Shell: The connection to the specified remote host was refused.

Hello All,

I have a Exchange 2010 Mailbox Server that displays the following error when trying to access Exchange Management Shell:

"Connecting to remote server failed with the following error message: The connection to the specified remote host was refused. Verify that the WS-Management service is running on the remote host and configured to listen for requests on the correct port and HTTP URL."

I verified that WinRM qc reports the following:

"WinRM already is set up to receive requests on this machine.

WinRM already is set up for remote management on this machine."

I did notice that when launching Exchange Management Shell the console hangs when trying to connect to the local Mailbox server. When I view the MSExchangePowerShellAppPool I see that the application pool goes from Started to Stopped.

Any ideas why launching Exchange Management Shell would be stopping the application pool? I would greatly appreciate any suggestions to correct this issue.

Moving public folders to new server

Hello, I know there are several topics about this already, but the answers are quite vague.

  1. I need to move public folders from Server A to Server B. The common answer I have seen to do this is the moveallreplicas script. What I am wondering is, is it literally I just run the script and the database gets moved? There is no prep work required or any other steps involved with moving the public folders/database?
  2. Is there downtime while the script runs and folders/database is moved?

apply public certificate to exchange 2010 setup

Thanks for your help.

My current setup are:

- 1x Exchange 2010 server (mail01) with all role as backend

- 1x Exchange 2010 server (mail02) with cas role as front end

- 1x TMG server as Reverse proxy

- using Internal self sign cert now to serve owa and outlook anywhere

- the server right now support receive mail for multiple domain  (around 5 domain)

- autodiscover DNS setting for each domain are already setup

Now I need to replace the self sign cert with a public signed certificate like symantec one and I've already wildcard cert for our main domain, eg *.example.com

After I review the steps when generate the self sign cert for frontend server (mail07), it included a few SAN entry for each receive email domain and this cert use on TMG server also to accept external request.

Question

1. if I use the wildcard certificate, it is not included those SAN records, anything will not work?

2. about the autodiscover services for other domain, does it work when using the wildcard cert?

3. how to handle for this case? and what is the procedure to apply existing cert to exchange 2010 and TMG?

Thanks for your help.

Upgrade to Exchange 2010 SP3 RollUp 11 Process/Requirements

Hi, Guys.

Need your assistance on this. 

We have a project deadline to be met wherein our Exchange 2010 infrastructure is to be migrated to O365. As part of the migration requirement, we have to update/upgrade our environment to Update Rollup 11 for Exchange 2010 Service Pack 3. 

Currently, our environment is sitting at Update Rollup 5 for Exchange 2010 Service Pack 3 (KB2917508).

Now, my question is, given our current infrastructure, are there any prerequisites/considerations to be done first before we move up to this Exchange level? Do we have to install/do something before we upgrade our environment to RU 11? Or is it okay now to directly upgrade our environment to RU 11 given our current infrastructure sitting at RU 5 SP3? Please also note that our Exchange server have multi roles [CAS, HUB, Mailbox roles installed on each of our Exchange node]. What/How is the process in implementing this update in our infra? Please advise.

Reallly Appreciate your help on this.

Thank you.

I have an environment with 3 exchange 2010 servers in the main AD site and one exchange 2007 server in another AD site.

All servers are multi-role except one Exchange 2010 in the main AD site which is only mailbox role as it is meant for archiving only.

The other 2 servers in the main site are both multi-role, and I have to remove one of them. When trying to un-install i get the following error (given below) on the mailbox role (and the un-install does not proceed to other roles after that).

,

 I've already  made sure this server has all the necessary stuff moved from it to the other multi-role server.

How can I Un-install this server?

Exchange 2010 to Exchange Online with dirsync (Hybrid)

November 4, 2015, 6:55 pm
$

Hi,

I am planning to sign the Exchange Online and migrate some users to Exchange Online and part will keep the Exchange On-Premises (2010).

I'm reading various documentation, understanding some possible scenarios, but stay with some doubts about the connection (Client Access) Microsoft Outlook for users who are migrated to Exchange Online.

These doubts arose because the documentation is guiding create a CNAME (autodiscovery.domain.com) for the A record (mail.domain.com) which is the NAT for my Exchange On-Premises. The receiving e-mail will continue to occur for my Exchange On-Premises.

Scenario:

- Mailbox Database configured to CAS (casarray.domaim.com / 10.10.x.x);
- All computers are in the internal domain (domain.com)
- In the External DNS I have the records:
  - Mail.domain.com / 200.x.x.x
- The Internal DNS I have the records:
  - Mail.domain.com / 10.10.x.x

In the scenario where the incoming mail will continue to be held by the Exchange On-Premissses (2010), I was wondering:

1 - Users who were in the Exchange On-Premises and migrated to Exchange Online. These connect to Microsoft Outlook via RPC / MAPI. Or you will not change at all?

 - Microsoft Outlook will automatically be reconfigured to use RPC over HTTP to the address (mail.domain.com / .10.10.x.x)?

 - If the answer is yes, it means that he allocated the mailbox in Exchange Online, the connection to the access client is the Exchange On-Premises?

2- If that user with the computer to the external network, it will resolve the name (mail.domain.com) with the external DNS, but he will continue to be transferred to the Exchange On-Premises and will be directed to Exchange Online?

3- Users who are migrated to Exchange Online, if there is any problem of internet access, your mailbox will be disconnected? Meanwhile, it is on Exchange On-Premissess continue working normally.

4- Users who are migrated to Exchange Online, open the webmail (mail.domain.com/owa/ - 10.10.x.x) it will be automatically directed to the webmail Exchange Online?

Thanks again.
