Is there a way to route email traffic from my server to another computer with 2 NIC cards installed;
one NIC on the same network segment as the server and the other on a different network?
the goal is to get email traffic routed from the server to the computer with 2 nic cards then over to nic on
the different network address

I updated exchange server 2010 a few days ago with monthly security rollups and have been having a problem every since.  Consistently, after several hours port 25 stops working.  When I try and send a test mail from the microsoft connectivity analyzer it says port 25 is not responding, and internal emaill sent on the LAN are to arriving either.  When I try and telnet on port 25 to the server it does not establish the connection.

I renamed the "transportroles/data" file so that exchange recreated it on reboot but that has not fixed the problem.

Outlook clients show outgoing mail in sent folder (not outbox) but mail is not going arriving (internally or externally) and not showing in exchange queues.  However, upon reboot all mail arrives.

No relevant errors in logs.

A reboot fixes the problem for several hours but the port stops responding again after that.

Any ideas on how to fix this without restoring from backup and not installing updates?

Thank you!
I am having difficulty running the MailboxExportRequest command on 2 new 2016 Exchange servers. It works properly on other previous Exchange 2016 servers I have configured. On these 2 new Exchange 2016 servers, it works fine on individual mailboxes where I provide the mailbox name, but not when I use the pipeline command for all mailboxes. The FilePath and ContenetFilter also work on individual mailboxes, so I don’t think they are a problem.

Exchange CU9 on Windows Server 2016 Standard VM

Commands I enter in EMS:
New-ManagementRoleAssignment –Role “Mailbox Import Export” –User “Administrator”
$Export = Get-Mailbox
$Export|%{$_|New-MailboxExportRequest -ContentFilter {(Received -gt "06/30-2018")} -FilePath \\DC2\Backups\PST1\$($_.alias).pst}

Error message that occurs 47 times (47 mailboxes)
The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.     + CategoryInfo          : InvalidArgument: (Microsoft.Power...FormatEntryData:PSObject) [New-MailboxExportRequest] , ParameterBindingException  + FullyQualifiedErrorId : InputObjectNotBound,New-MailboxExportRequest  + PSComputerName : “”
Please help.
I have a requirements in exchange Server 2016 related UPN Suffices.
 In Details make a scenario as, i have configured a root domain as "" and i added additional UPN Suffices like "black.local",
"" and others too. Whenever i creates a users then i get the options of all UPN suffices whatever i added. User mailbox is created as its accepted domain. by default ECP Directories is ""

Now requirement is : 1. when i login the Exchange ECP, with my URL "" or with any other upnsuffices i provided. now when i try to create a users then needs only the required Suffix. Means, i only needs the 1 option suffix like "black.local" not others suffices.
2. And in recipients panel, only show the users mailboxes related "black.local" not others.

this two process needs to configure for all add upn suffices.

Can we do this? Please help, how can we configured this.

Now, 300 Users Mailbox jam in the CASHUB queue delivery.

Dear Experts

Please can someone assist me.

I have the following setup:
Multiple accepted domains
Exchange 2010 hybrid with Office 365
90% of the mailboxes are in the cloud
Cloud mailboxes sent out email straight from Office 365
On premises mailboxes sent out via our Cisco Ironports

I would like for one of the accepted domains to send out all email via Office 365 even for the on premise mailboxes. Just for one of the accepted domains thou.

Now that I have email flowing in both directions I have one minor problem internally
I have many Windows servers on my network that email status reports o a daily basis.
They are all powershell scripts.  

The only change I made to the scripts was this line
$PSEmailServer = "SERV025.MYNET.COM"
$PSEmailServer = "SERV021-N1.MYNET.COM"

The scripts are duplicate on all servers

They are all setup in Task Scheduler.

They all run and I know this because I keep the log file in a log folder on each server and I check that they are there with current time stamps.

My problem is that I do not always get the email sent to my inbox.

My variables are this

$Server = hostname
$Subject = "$Server Daily Event Report"
$Body = "Open attachment for Todays Events Report"
$From = ""
$To = "" in a distribution list

This i a header of one that came thru.

Our exchange server has stopped responding to port 25 smtp requests.  It has done this 3 or 4 times over the last week. I have not been able to find the cause. Restarting the server does correct the condition (temporarily).
Hi Experts,

I am using Outlook 2010 and  Outlook 365 with MS Exchange . I heavily rely on Tasks, and often flag an email in order to make it as task.

I usually hide the folder pane in order to have more visibility, but I notice sometime the task goes to my Task folder for my email account and not to my To-Do List.

I have noticed that the between the two is that the To-Do List shows my flagged emails, where as my Task folder does not.

My question is, how can I make the Tasks always go to my To-Do List and perhaps make my other task folders hidden or deleted; or how can I make flagged emails also appear in my Task Folders?

Thank you,
What exactly is this error bec keep receive it and how to check whether it has an impact to the exchanger 2010 server? I can’t sleep when I am on night duly. Tks.

Alert description: The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.
Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
I got a weird one that we have been fighting for sometime now. In our Exchange 2013 environment, we are constantly running into SMTP timeout issues  when trying to send emails to non-Exchange environments. For instance, when Exchange goes to make that handshake, after a 15 second timeout, the connection just breaks and cant do anything outside of having the recipient white list us. Problem is, this is only happening to one client out of 100 that has the exact same setup. Its the timeout issue and cannot find anywhere to tell SMTP to go beyond that 15 second SMTP and wait until the other end proceeds with the greeting. Any ideas would be greatly appreciated.

I have an Exchange 2010 server. I have an certificate about to expire, which is no problem as I’ve renewed it several times over the years. My question is, There are 2 other Certs in the Exchange Certificates windows that I’d like to delete, I didn’t create, and have been there since installation. They don’t expire anytime soon but do I need them? Can I just use one Cert? I didn’t create them.

Attached image – The 2 with the blue check are the ones I’d like to delete if I can, the Ranger Certificate is the one I make when from time to time when it expires and as far as I can tell the others don’t do anything. But before I gut them I’d like to make sure.

Thanks for the help

We are going to migrate our exchange server 2007 mailboxes to 0365 using exchange 2013 hybrid setup. Please see the attached the mail box size of users.

We have a 100MBPS ISDN connection and I have been given 15 days to complete migration the mailboxes to 0365.

Please let me know if this will be achievable or if I need to take any precautions, or necessary steps in advance.

Any help will be great.


We are going to migrate our exchange server to 0365. We use backupassist software  for backing up the exchange database and I exported some mail boxes locally and copied to my desktop PC and when i open through outlook client  2013, it says
Microsoft Outlook -File access denied. You do not have permission required to access the file C:\Restore 001 – 11 –User name.pst.

Please help and any suggestions will be great.
Hello Guys,

One month from now I will be implementing an Exchange 2013 to 2016 migration. I would like to seek your assistance if you have a documentations and scripts on your end that applied on your organization successfully. And also I have a bit of concern after the migration. I will implement also DAG but it is not on the same area. Svr1 is located on the client HQ and Svr2 will be on the other place. Is that possible? I need your expertise. Thank you!

Have a SBS2011Server scheduled to be decommissioned by the end of the year. In the meantime looking to free up space on the partition that data is housed on. Current partitions are C:\ operating system; D:\ data and exchange database; and E:\ pagefile.

Because of other factors it makes sense to move the exchange database to the E:\ drive which will free up plenty of space on the D:\ drive where data is located.

Any concerns running the page file on the same partition as the exchange database?
I'm running 2x Domain Controlers (3t & 3t00 Win Server 2016 CU10) on the same domain with 2xExchange server (Mailbox Exchange 2016 ) configured with DAG. When both servers are online owa & ecp works fine. If 3t goes offline (which is the first server that i configure with AD and Exchange), then owa & ecp on 3t00 return blank page after log-in and Outlook won't connect.
I tried SSL Certificate change at bindings, also I recreated Certificates and finaly i tried recreation of owa & ecp VirtualDirectory.
I can connect to EMS at 3t00 and Exchange seems to work.
Any help to make 3t00 to work even 3t fails?
Hi Experts,
What ports do we need to open to be able to run the network performance assessment for Office 365? FYI, we are only looking to use Exchange Online, Desktop Applications (none of the Skype, Teams..etc offerings). We were able to install the executable file and for some reason can't connect to our tenant.

Thanks much!
