Hi there,

Exchange 2013 cu21 running on win2012 std r2 servers running in 2 nodes DAG in different network segment, connected via ipsec vpn.

All in a sudden, in Failover Cluster Manager, observed one cluster node up, one cluster node down.  No matter what we tried can't bring up the problem cluster node.

After very time-consuming troubleshooting, eventually found that it was due to some problem in firewall which routed the udp3343 traffics via public wan interface, instead of the internal ipsec vpn interface.  Anyway after fixing the firewall routing problem, in Failover Cluster Manager, both cluster nodes up, both cluster networks up, seems back to normal.

However, if run validate network, it keep saying failure node1 but success node 2 as below:

My question is, if packet loss is 0%, why node2 is not reachable from node1?  How can I further troubleshoot this strange case to make node2 reachable from node1 in network validation test?

Thanks in advance for your help!

Hi,

We have 2 Exchange mailbox server 2013.

One of the Servers is removed physically. We could not perform any decommission activities on that server. It is not possible to bring it back as it is crashed.

As of only one server is there in DAG. Please let me know how to remove the metadata of failed server. We would like to use the same name and IP address for the new server that we are going to deploy.

Hi there,

Exchange2013 cu21 on win2012 std r2 server, in 2 nodes DAG, server1 as primary, server 2 as secondary, each server in different site, connected via ipsec vpn.

Today conducted regular maintenance reboot with below procedures

1. put server2 into maintenance mode, reboot, get server2 out of maintenance mode

2. put server1 into maintenance mode, reboot, get server1 out of maintenance mode

Right now all email services resumed, all DB mounted on server1 as usual, mailboxreplicationstatus healthy.

However, observed a few "components" seems missing on server1 as below:

Any idea why DBCopySuspended, DBCopyFailed DBInitializing, DBDisconnected, DBLogCopyKeepingUp, DBLogReplayKeepingUp is missing in server1 when check with test-replicationhealth?  How to fix?

Many thx!

Hi Support,

We need to export user data in PST to a local drive from Office 365.

The user data includes, Sharepoint data, one drive data and mails.

If pst export is not possible for sharepoint and one drive data, any other format is also okay.

But when I did a content search or ediscovery to export a mailbox content completely, I can only have sender, recipient like options to search. It means I will have separate psts for inbox and sent items.

Last year or so I was able to follow the article below.

https://itgroove.net/kinglou/2017/01/12/export-to-pst-from-office-365/

Now options are changed and I cannot search entire mailbox separately, I have option like sender, recipient, sent ,receive, date etc. Please correct me if I am wrong here. Also let me know regarding below query.

Please let me know any other microsoft or third party free tools to export a complete mailbox as a single pst.

Anyone had experienced this error on Exchange 2013 on Exchange powershell

Hi Guys,

I have recently added a new disk to our exchange server.  

I would like to use this disk as a location for the passive copy of a particular database.

When i try to create a passive copy of an active database, it defaults to a different disk.  This disk is currently full and cannot be expanded.

Am i able to force the passive copy to be created on the new disk?

If so, can someone please provide the steps.  I have tried following this article, but cannot find how to force a copy to point to a particular filepath.  It only describes how to create a copy and when i do, it tries to create it on the full disk not the new, empty one.

https://docs.microsoft.com/en-us/exchange/high-availability/manage-ha/add-db-copies?view=exchserver-2019

We are using Exchange 2016 and the database is part of a DAG.

Your help is appreciated

Hello,

We are using Exchange 2013 cu21 , we have 2 cas servers (1pr/1dr) and 3 mailbox servers (2pr/1dr). Today i tried to update one of the mailbox server on production. When the update finished, i restarted the vm. I run test-replicationhealth on this server and i get the following output:

Then i tried a get-MailboxDatabaseCopyStatus... here is the output:

The CopyQueue Length is increasing, i checked that by re-running the MailboxDatabaseCopyStatus after 20mins.

What i have to do to have a healthy database again? If i restart the vm it will change anything or not?

Thank you

Hello,

I have a question regarding the resiliency of my Exchange environment and some outages that we experienced lately. 

My environment currently consists of 4 physical multifunction servers in two different datacenters. All four servers are members of the same DAG, we use a file server as our Witness server. My databases have been setup so that passive copies reside in the opposite datacenter. Example: datacenter1Server1 replicates to datacenter2Server1.  All four serves have active and passive copies of databases.   We use a Citrix Netscaler to load balance the client requests.   

When I do my server maintenance during a time when there is a light load I’m able to take two servers from the same datacenter offline without any interruption of service. During the day during peak load my entire environment fails if I lose the same two servers from a single datacenter.   The failure will continue even once the two servers have been restored. During the failure all the nodes of my cluster will continuously flap between being online and offline. That issue will continue until I reboot all four of the severs.  

It appears that two remaining servers get overloaded by all the new connection requests coming from clients that are reestablishing their connections.  Does that sound correct?  If so, does that mean our server hardware is under sized? Is there a configuration change I can make to correct this?

Thanks

Jeff

Hi All,

I have 2 Exchange Server and both installed CAS and Mailbox Access roles.

And i have DAG configured in both servers for Mailbox server HA. And Enabled Replication for our Databases.

My Question is:

What will going to happen if Primary Active Manager is going down in 2 node exchange server?

How to we make sure all our Exchange client connectivity and Mail flow is happening from Second Exchange server?

Thanks,

Hi All,

I'm facing issue during installation Exchange Server 2013 Cumulative Update 22 on secondary Exchange server. For information,my organization have deploy DAG environment and both server MAIL01 and MAIL02 is running on Exchange server 2013. Yesterday I've successful install CU22 on MAIL01, and today I'm tried to do that on MAIL02. During installation CU22 on MAIL02, the installation was stop due to below error:

Exchange Server component Mailbox role: Transport service failed.

Error: Error:

The following error was generated when "$error.Clear();

       if (get-service MSExchangeServiceHost* | where {$_.name -eq "MSExchangeServiceHost"})

       {

           restart-service MSExchangeServiceHost

       }

       " was run: "Microsoft.PowerShell.Commands.ServiceCommandException: Service 'Microsoft Exchange Service Host (MSExchangeServiceHost)' cannot be started due to the following error: Cannot start service MSExchangeServiceHost on computer '.'. ---> System.InvalidOperationException: Cannot start service MSExchangeServiceHost on computer '.'. ---> System.ComponentModel.Win32Exception: The dependency service or group failed to start

  --- End of inner exception stack trace ---

  at System.ServiceProcess.ServiceController.Start(String[] args)

  at Microsoft.PowerShell.Commands.ServiceOperationBaseCommand.DoStartService(ServiceController serviceController)

  --- End of inner exception stack trace ---".

  I'm tried to figure out by google any info but not luck to solve this case. Also I notice all Exchange services on MAIL02 not running and cannot start even startup is automatic. I've tried to reboot the MAIL02 few times and re-install CU22 but installation Setup not prompt.

For time being, I'm only active the MAIL01 as primary and database mailbox copies on MAIL02 still remain suspended.

Appreciate if you could assist on this issue.

Best regards, Matt Fauzy

Hello Folks,

We are seeding mailbox database to DR server which is installed on the HQ site ( Later will shift it ).

We have total 6 Databases out of which 4 Databases completed successfully but the DB05 has some problem.

Note: Once Databases seeding completed we are shifting the DR Exchange Virtual Machine to DR site so do we need to enable DAG Maintenance as one of the member will be unavailable for few hours. 

Error Details:

Appreciate your suggestions

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. 

I have multiple exchange 2013 Servers in DAG both in DC and DR site. In many of these servers my exchange replication service is terminating unexpectedly multiple times in a day with below error .

Event id 4399

The Microsoft Exchange Replication service is terminating without collecting a Watson dump. Error The Microsoft Exchange Replication service is using too much memory (4100.6171875 MiB) and will be terminated without collecting a Watson dump. This exceeds the maximum expected value of 4096 MiB. To take a dump along with the Watson report, set registry key 'SOFTWARE\Microsoft\ExchangeServer\v15\Replay\Parameters\EnableWatsonDumpOnTooMuchMemory' to 1. Default can be overridden by setting registry key RegKeyBase=SOFTWARE\Microsoft\ExchangeServer\v15\Replay\Parameters;RegValues=MaximumProcessPrivateMemoryMB,MemoryLimitBaseInMB,MemoryLimitPerDBInMB;EffectiveLimit=Min(MaximumProcessPrivateMemoryMB,MemoryLimitBaseInMB+nCopies*MemoryLimitPerDBInMB)

I searched for this error and got to know that its a known issue in exchange and the followed below article to apply the workaround 

https://support.microsoft.com/en-us/help/2892330/msexchangerepl-exe-process-terminates-when-you-try-to-replay-more-than

Even after applying the workaround, though the frequency has reduced by half but still the service is getting terminated with same error, just that now the error is saying that "This exceeds the maximum expected value of 6240 MiB"

prior to applying workaround the event id used to show limit as 4096.

I have applied below registry settings as per the tech net article.

Hello everyone

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

Problem: Exchange logs are not flushing after backup exec runs full backup.

The backup in backup exec 2010 R3 Is successful. It is also set to do full backup/flush logs

The logs fill up to around 50,000 files or more. How do you fix this?
