Exchange 2013 cu21
we have a "load balancer" that is not actually doing load balancing. as i have two CAS servers, when i reboot CAS01 the load balancer is still pointed to CAS01 thereby the users loose connectivity.
i searched for a better alternative and come across DNS round robin. some say it is the official way supported for HA?
Hi,
I have a DAG with 2 Exchange 2013 servers (EX01 and EX02) and 1 File Share Witness server (FSW).
Everything is running fine apart from I notice that the Queue particularly the Shadow Redundancy
is not clearing.
I have a couple of incoming emails in the Shadow Redundancy Queue that is meant to be delivered to the end user
But it is not appearing in the end users mailbox.
The Status of the email in this Queue is showing Ready. The message count for the Shadow Redundancy Queue
on both Exchange 2013 servers in the DAG are different:
Example:
EX01 - 47 (message count)
EX02 - 78 (message count)
My questiones are:
1. How can I get the emails in the Shadow Redundancy Queue to the end user mailbox? Is this possible?
2. Are the emails in the Shadow Redundancy Queue just copies of the emails which should have been sent to the end users mailbox?
3. Why are emails appearing in the Shadow Redundancy Queue?
4. Is it normal for both servers to have different message count? Presumably it is.
5. Should I worry if the message count in the Shadow Redundancy Queue keeps going up?
Just to reiterate, external emails are coming in fine and end users are receiving them but there are a few that are in the
Shadow Redundancy Queue that is not being delivered to the end users mailbox.
Kind regards

hi all,
currently we have exchange server 2013 , we have owa.domain.com configured to IP address 10.10.10.10 same as the ip address of Exchangeserver01(hold both Role Mailbox and CAS ) 10.10.10.10 the active node.
now we have added to new exchange server and we make DAG and database replicated ,in case the first ExchangeServer01 is down how the traffic will be forwarded to another ExchangeServer02 to achieve high availability .
what is the best in this scenario ?
Thanks
On an Exchange 2013 DAG, during a Veeam backup, I am seeing eventID 2153 logged on exchange server that a timeout has occurred. The log copier was unable to communicate with server xxxxxx. The copy of database yyyyy is in a disconnected state. The communication error was terminated by server xxxxxx The copier will automatically retry after a short delay.
I cannot find any timeout settings that I can adjust to work past this.
Can some body help me.....how can i import my EDB file into Outlook file format
Please help me....
Hi,

Hi Team,
I am having Exchange 2013 running on windows 2012 R2, I have multiple CAS & two mailbox server for DAG @ HQ. But our current Exchange server is having multiple issue, so we are planning to build new Exchange server 2013 2 CAS with HA and two other servers for mailbox dag.
I need the suggestion how should i take forward as a best practice do i need to migrate or is it straight forward. I am planning to have site resilience also at different site, Need guidance for that too. I will be having one sever for CAS and one for mailbox, let me know how to configure the site resilience.
All the above servers i have mentioned running on Virtual environment Vmware.
Expecting a positive reply
Thanks & Regards

Now I have done the DAG configuration successfully. I don't have a load balancer in place. I tried the DAG test and the database successfully switchover to another server. but my owa/ecp are not working and also all the outlook clients got disconnected.
Just now i added the DNS entry for new dag member in DNS server. and will give a try the switchover again after sometimes. and let you know the updates.
Right now my firewall is port forwarding to one of my existing exchange server (for External OWA/ECP access)
What if that server is down ? how can i access OWA/ECP from outside network? Can i port forward to two CAS server in firewall ? By the way i am using a ssl certificate with added entries "www.abcd.com, abcd.com,autodiscover.abcd.com".
MS Exchange 2013
4 nodes, 2 DB and 2 CAS
Issue : Adding passive database copy failing for one database.
I already have other 5 databases with active passive copies running fine.
When i try to add DB copy in GUI, It will stop after 15 seconds with below error
The seeding operation failed. Error: An error occurred while performing the seed operation. Error: Communication was terminated by server 'SourceServer': Data could not be read because the communication channel was closed. [Database: DBname, Server: DestinationServer]

I have tried above method multiple times ,Also tried postpone option while adding DB copy.
Restarted both Exchange DB servers and tried
Deleted the passive copy along with db and log folders and tried to add fresh copy
Also restarted search services and tried
=====
Also tried Update-databasecopy with -databaseonly and -catalogonly switches. this also throws errors
Also tried below :

Really appreciate your help

Hello -
I am using DPM 2012 R2 to backup my Exchange 2013 DAG members (currently, database only).
I now want to add to a different backup job the rest of the server. volumes (C:\, data drives, system state, etc)
DPM allows me to exclude specific folders or specific filetypes.
1) Do I need to exclude any specific folders or filetypes from the job?
2) If so, what should be excluded?
Thanks!
I have exchange 2013 2 MBX in DAG environment with 4 DBs one of the DAG nodes encountered the trust relationship issue and unfortunately most of the activated DBs was reside on it.
the steps that I have took was performing a dial tone recovery as the below steps:
created a new dial tone DBs (DTDB1,DTDB2,DTDB3)
Rehomed the users from DBs to corresponding Dial tone DBs except 2 DBs I homed them in the one dial tone DB :(
Get-Mailbox -Database DB1 | Set-Mailbox -Database DTDB1
Get-Mailbox -Database DB2 | Set-Mailbox -Database DTDB2
Get-Mailbox -Database DB3 | Set-Mailbox -Database DTDB3
Get-Mailbox -Database DB4 | Set-Mailbox -Database DTDB3
Fixed trust relation issues and the lost server become alive again and all replications are working properly.
before going to the production I tested on my lab to rehome the users back to the original DBs but have 2 issues.
Get-Mailbox -Database DTDB1 | Set-Mailbox -Database DB1
Get-Mailbox -Database DTDB2 | Set-Mailbox -Database DB2
Get-Mailbox -Database DTDB3 | Set-Mailbox -Database DB3
Get-Mailbox -Database DTDB3 | Set-Mailbox -Database DB4
1. the 2 DBs that I homed on the same dial tone DB some of them encountered an error message on OWA (your account has been disabled) because that users are homed backed to the wrong DB.
2. the messages that sent and received during dial tone period how can I merge them with the original database.
Hi,
How do i configure Voicemail capabilities if the user's mailbox and S4B is hosted in ONprem in a Exchange HYbrid environment, if the user does not have a deskphone
Long story short our Exchange 2013 server completely tanked.
After starting over, reconfiguring raid, installing 2012 R2, installing Exchange 2013, and recovering the install files from a backup I realized the name of the server was a letter off (sigh). I know renaming an Exchange server generally isn't good, but nothing was working as it was since all of the mailbox databases were linked to the correct name still. I went ahead and renamed it. All of the databases are in clean shutdown and ECP works. However, I get a transient error (MapiNetworkError) when trying to mount them.
Anyone have a suggestion on what to do next? Since it's already been down a full day I have some people breathing down my neck, so reinstalling it all again is a very last resort.
We have Exchange 2013 sp1. We have 2 servers in DAG. We have added one more and when trying to replicate the database copy to new server, we receive below error.

Hello everyone,
So i've done the following:
Restored my DC's (2x Server 2012 R2)
Created a new, identical, server. Same name, ip, joined domain etc (1x Server 2012 R2)
Installed all pre-requisites
Tried to restore one of my exchange server with:
.\setup /m:RecoverServer /IAcceptExchangeServerLicenseTerms
Now i get the following error:
Performing Microsoft Exchange Server Prerequisite Check
Configuring Prerequisites COMPLETED
Prerequisite Analysis FAILED
The Exchange server is a member of a database availability group.
Note: I don't have any live Exchange servers in this environment at the moment. (since they are both crashed un-repair-able)
I've installed Exchange Management Tools on another server, but it can't connect since both exchange servers are gone. Any idea how to solve this?
Kind regards,
Justin
Hi all,

Hello, we have exchange 2013 after hard recovery from backup vhd couple month ago old. Backup is damagen and we has recover probably only pst with public folders. And there is problem. One public folder has been created few week ago. We wos recreate this folder (mail enabled) new but we can not add mail address becouse exchange server (probably in active directory) has usage. How to clean or add this important address to public folder?
There is error message:
"-domain-"/Microsoft Exchange System Objects/"-alias-" 10744667
The proxy address "smtp:-mail address-" is already being used by "-domain-"/Microsoft Exchange System Objects/"-alias-" . Please choose another proxy address.
Hello Folks,
We are planning to extend exchange 2013 DAG to DR Site.
First AD part:
Currently My AD has single site ( Default-First-Site-Link ) and has two domain controllers 2012 R2.
For DR site, planning to install one more domain controller, I think i should create a new site in Active Directory sites and services as DR site.
My queries ( Below is my procedure i am doing it in correct way )
First DR site should be created in Active Directory correct ?
Adding the DR site Subnet as well
Then Inter-Site Transports > New Site link and adding both the Sites ( Default-First-Site-Name ) and ( DR Site )
After adding the sites i will create a new machine at DR site and promote it as a domain controller ( Ofcourse i will consider the ports and services between two sites for network traffic )
Once All the domain controllers are replicating then i will start the exchange part.
