my passive servers showing this errors Failed and suspended . So i searched it how to solve.

https://blog.brankovucinec.com/2015/10/02/fix-the-exchange-2013-content-catalog-index/

Follow all these steps. And after few mins 2 database shows crawling and copyqueue a big number which is increasing from last few hours.

 2264541 this much big number

What's the root cause behind this failed and suspended databases ?

The PublicFolders Health Set has detected a problem with PublicFolderMailbox.ConnectionCount at 12/13/2016 1:32:01 PM. 0 failures were found. The Health Manager is reporting that The total number of hierarchy connections for public folder mailbox \ has reached 2001. Consider creating a new public folder mailbox for load balancing hierarchy accesses. 

So the scenario is that we have 8 databases . 4 active and 4 passive.

All stored in the F drive whose size is 2.5tb. Now only 100gb left that's why we are getting  suspended and crawling issues.

Now my suggestion to the company is that why don't you make 8 different drives of 1tb each which is extendable to 3tb without restart. and copy every db over there.

So you already seeing in that pictures is that we don't have DAG working properly.

How we proceed next ? do we first increase the disk space and come out this situation temporarily. Then we make separate 8 diskspaces and start coping ?

IS there any way in which we don't get any down time ? 

Hi all,

been trying to find some information about what these connectors are used for in Exchange 2013.So far i have understand that FrontendTransport in for CAS servers and HubTransport is for Mailbox servers.

can anyone explain me in short terms of what these connectors are used for?

Properties of these connectors varies,but all of them have security tab with these configurations:

Are there any easy rule on how to set these authentications?Like if one connector is meant for Internal communication and one is for External communication?

Appreciate all your answers!

In advanced thanks

Hello Everyone

         Current I have installation new server windows 2012 and install exchange 2013 CU8 after that I add it to DAG then it show error

Hi 

We have a critical situation

our backup solution is crashed (will be up after 4 days ) 

I need a way  to backup the exchange servers (mailbox servers) 

can windows server backup works for this or there is another way

Hi,

We have 2 Exchange 2013 servers (CU10) with a single DAG. We experienced some unexpected database failover.

Event 126 from ExchangeStoreDB:

At '23/12/2016 18:29:55' the Exchange store database 'Small_db1' copy on this server encountered an error that caused the database to be dismounted. For more detail about the failure, consult the Event log on the server for other "ExchangeStoreDb" or "msexchangerepl" events. A successful failover restored service.

I am failing to understand what happened here. I checked the mailbox with the GUID (mentioned in Event 1013) but there seem to be no corruptions. 

Any help would be very welcome. Please don't hesitate to ask if you need more information. 

Hello Frens,

Iam in a trouble pls help,

My Environment:

3 CAS servers: CAS1,CAS2 & DR-CAS1,  4 MBx server: MB1,MB2,MB3 & DR-MB1.

Dag name: OVL-DAG, Witness: CAS1,  Members: all 4 MBx servers.

Databases: 6 DB's in DAG

SIte A: CAS1, CAS2, MB1, MB2,  All DB's mounted after running 'Start-DatabaseAvailabilityGroup -Identity OVL-DAG -MailboxServer OVL-MB1' on server MB1. Mail flowing via site A.

Site B: CAS1, MB3, All DB's mounted

Now the WAN link connecting A and B is down. All 6 copies on MB1 were in Active & Dismounted state. Now All DB's were mounted in site A after running 'Start-DBavailabiitygrp-Identi OVL-DAg -Mialbxserv OVL-MB1' on server MB1.

 All DB's are mounted on both sites, I need to run mail flow from Site A and need to remove MB3 after decommissioning.

but before decommissioning i need to bring all DB's copy in MB3 to passive state (currently ACtive Mounted, Healthy).

Urgent help is solicited. Thanks in advance

Hi,

  my plan is to install a new Hyper-V  2016 cluster. My plan is to run Exchange 2016, SQL 2014/2016 (Navision C5) Exchange

  sever 2016, Domain controller 2016 and Terminal server 2016. I will be using two identical Tower servers HP Proliant ML350

  Generation 9, and to have two Physical drives i.e. C drive  300GB for host system and HyperV sso (fast disks) mirrored and E drive   1.5TB sso  Raid10  for VM's.

  What confuses me is if I create a two not Hyperv-v cluster do I need to create a DAG for the Exchange server or SQL cluster as 

  well? Is the Hyper-V cluster covering a Hight Availabilty for all the servers on it.?

  thanks

Hello All,

Please find our current AD and Exchange Scenario for HO Office

2 AD Server OS 2012 R2

3 Exchange Servers 2013 Typical Installation ( Mailbox and Client Access on the same machine ) Databases are on SAN

DAG is configured on the exchange servers.

Note: All servers are physical only

We are planning to have a DR and below are the details.

DR Site

Hyper V Cluster 2012 R2 with SAN Storage

AD will be installed as a Addtional Domain Controlller ( Virtual Machine )

Exchange will be installed on the virtual machine as Typical Installation ( Mailbox and ClientAccess Role ) ( Virtual Machine )

Site to site VPN connectivity will be established between both the offices.

Now my question is can we do the above setup to meet the AD and Exchange High Availability.

I understand AD should be fine but i have doubt on exchange whether my plan is correct or wrong.

Please share your ideas and help me with links

Thanks,
Arif

Hello, 

I have been using Exchange server 2013 for a week on single box called EX.tom-af.com and everything worked fine. After a week I added another server (EX2.tom-af.com) with both roles on it for MBX and CAS (with round robin DNS) high availability. DAG is working fine, however, only some users getting long delay on delivery or even failure. I think they are those users who their messages are going through EX2.

Also, when I check on delivery report, I get this error message: 

"Server EX.tom-af.com in domain tom-af.com encountered an unexpected error. Diagnostic information for this error: The message-tracking data on server EX2.tom-af.com had invalid data in column 12 for this message. Event "THROTTLE" will be ignored."

Can anyone tell me when which setting I should go through and make sure they set properly, so I don't get this error as well as delivery delay?

Thanks!

Hi guys,

Could some point me to some of the best e/mail archiving solution out there.

I am concerned with the way we are creating psts.

The mail remain in a queue called server02\Unreachable and the error is this: "There is currently no route to the mailbox"

Do you have any solution?

Thanks.

Hi,

I ran into a problem with our 2013 Exchange server CU14. When checking MailboxDataBaseCopyStatus, all our databases had ContentIndexState "failed". I found an article that showed me how to rebuild the contentindexdatabase. 

The procedure was to stop "Microsoft Exchange Search Host Controller" and "Microsoft Exchange Search". Delete the content index located with the database. After deletion restart the services.

This worked on 2 out of 3 databases. Now we have 1 database still crawling, and it has been doing that for days now. When checking the index of the crawling database. I see that it has 9 databases to crawl, and index errorcode 3. This has been like this for days. After the crawl index seems to stop growing in size (checked the GUID.single folder), we also get an error in Event Viewer saying that Microsoft Exchange Search Server service terminated unexpectedly. This now happens every minute. The server is under heavy CPU load as the noderunner is taking a lot of CPU.

I just did another rebuild of the crawling database, but it seems to have stopped at the same mailbox as it still has 9 mailboxes to crawl.

I read somewhere from a guy that had a similar problem, that one of his user a problem and was causing the mailbox to stay in an endless crawling loop. Is there a way to find out which mailbox the crawling is currently at?

Is there anything else i should check to solve this problem?

Hello,

We have 6 node DAG. 

Mailbox Database copy configuration is: 1 Active copy, 5 Passive copies.

To put the server in maintenance mode I would like to move active copies from server1 to other servers as per their activation preference.

I can use "Server Switchover" open EMC to perform this action.

But I want to perform this task using Powershell.

Is there any command available to achieve this?

-Thanks
