Exchange Server Mailbox Migration

Hi All,
I just migrated a 2.2 GB mailbox with 50k item count from Exchange 2010 to Exchange 2007 sp3. After migration the mailbox is 3.7 GB in size with 70k items.
Can anyone shed any light on this. there is no way the user got 20k mails during the move.
Thanks

Hi,
You can use the following command, it will display all columns.
Get-MailboxFolderStatistics -Identity "[email protected]" | ft name,foldersize,*item*
Please check and find the folder, the size and item of this folder increase abnormally, as what S.Nithyanandham mentioned.
You can check the folders in Outlook and see what kind of items are added after migration.
Best regards,

HT4796 Is it possible to migrate Exchanger Server mailboxes to an apple enviornment?

I would like to find out if it's possible to migrate Exchange 2007 Server Mailboxes to an Apple Environment. If the answer is yes, does anybody knows how this can be achieved? What tools and methods will be used and are there any requirements in terms of H/W, S/W, O/S, etc...

You could connect your old MacBook to your TV with an adapter cable and play directly from it as well as stream from shared libraries. Depending on how old your MacBook is, however, you may need to use a separate cable for audio and the video quality may not be as good as with an ATV.

Exchange Server 2013 migration and high avalability

Hello,
We are using Office 365 online and will be migrating onto an in-house Exchange Server 2013 on a new Windows Server box.
I have two questions:
1. What is the best way to migrate everything from the Office 365 to the in house server? Do I setup a hybrid environment and then move the mailboxes and then remove the hybrid environment?
2. What is the best way to setup high availability for the in-house Exchange server? I found out that in order to setup Exchange 2013 as high availability it needs to run on Windows server 2012 STD or Windows server 2008 Enterprise.
Please let me know and provide links to step by step instructions if possible.
Thank you, Karel
Thank you. Karel Grulich, MCSE, SBS

Hi Karel,
Thank you for your question.
In addition Ed’s suggestion, moving mailbox form Exchange online to Exchange on premise could be refer to the following link:
https://technet.microsoft.com/en-us/library/jj906432(v=exchg.150).aspx
Exchange 2013 high availability could be referred by the following link:
https://technet.microsoft.com/en-us/library/dd638137(v=exchg.150).aspx
If there are any questions regarding this issue, please be free to let me know.

Exchange 2007 to Exchange 2013 Mailbox Migration (moved twice)

I have an Exchange 2007 mailbox that I migrated to Exchange 2013 and works fine. I migrated it back to Exchange 2007 and still works fine during coexistence with Exchange 2013. I try to migrate the mailbox back to Exchange 2013 and now it won't open in
Outlook 2007. It says disconnected when it's trying to connect. I can't figure out what's causing this.

Hi,
According to your description, I understand that all mail client works fine after migrate mailbox form Exchange 2007 to Exchange 2013, however Outlook 2007 cannot connect to Exchange server when mailbox moved to Exchange 2007 then move back to Exchange 2013
If I misunderstand your concern, please do not hesitate to let me know.
Basis on previous steps testing, the mailbox and mailbox database is available in Exchange server. How about another computer with same Outlook version and problematic account?
If it works in another client, please open Control Panel\User Accounts\Credential Manager in problematic computer, then clear the remains credential and try again.
This issue may be related to the connection between Outlook and Exchange server, please click “Send/Receive All Folders” or “Update Folder” to update data. Also, run Test E-mail AutoConfiguration and Outlook Connection Status with problematic account to
narrow down issue. Please post relevant error message, it’s more helpful for further troubleshooting.

Exchange 2013 mailbox migration from third party cloud to on premises

Hi,
we are currently utilizing a third party exchange 2013 cloud service to host user's mailboxes ( intermedia), now we implemented an exchange 2013 on-premises environment in Hyper V infrastructure and want to plan migration of mailboxes and related configuration.
cloud and on-premises environment have same SMTP domain ( Eg: XYZ.ORG) and currently an additional Temporary SMTP domain ( XYZ.CO ) used to test the external mailflow of on-premises since xyz.org is registered with cloud.
we need to migrate all mailboxes to on premises and enable XYZ.ORG for on-premises.
Pls suggest the prerequisites,steps, best practices for migration
Thanks in advance.

Hi Sumesh,
1. Please make sure your mails are flowing correctly using XYZ.CO domain. Hope you have XYZ.ORG also created in Exchange.
2. Hope you already created the users in your Exchange2013 server and distribution groups for current users
3. You plan a weekend for changing your MX records.
4. Change MX and A records to a lower TTL days before the migration to decrease DNS update time on migration day
5. Export Hosted Exchange data for each user to PST files using the PST capture tool and move your PSTs to a centralized location.
6. Change MX and A records to point to on-premises Exchange 2013
7. Import Hosted Exchange data from PST files into the new Exchange profiles
Please check these as well

Exchange 2007 mailbox migration question

Hi, I'm using Exchange 2007 and had most of my mailboxes are currently on a single mail server. I recently built two new mail servers and used CCR. I have 7800+ mailboxes and was told that when I move the mailboxes from the old mail server to the new
mail server that this will create a huge amount of additional transaction logs that wouldn't be cleared out until the next backup. We do nightly backup and have 1 TB of free space on our log drive. I can't find anywhere that documents that moving mailboxes
from one mail server to another would create additional transaction logs. I could understand the existing transaction logs would follow the mailboxes to the new mail server, but I don't see where it would create new transaction logs? I'm planning on moving
only 200-300 mailboxes a night, so this wouldn't happen all at once.
Any clarification would be helpful.
         Thanks,
          Andrew

Agree with Cara on this and the transaction logs can be fairly hefty in size when migrating a bunch of data. One other option would be to;
1. do a backup of the associated stores/database right before migration.
2. then run on circular logging for those all databases within a storage group which will keep the logs in check
3. upon completion turn circular logging OFF, do a full backup and proceed along your way.
There is however some risk with using circular logging and you should read the articles below
http://exchangeserverpro.com/ems-enabledisable-exchange-server-2007-circular-logging/
http://technet.microsoft.com/en-us/library/bb331968%28v=exchg.80%29.aspx
http://technet.microsoft.com/en-us/library/bb331951%28v=exchg.80%29.aspx
http://blogs.technet.com/b/scottschnoll/archive/2011/06/27/circular-logging-and-mailbox-database-copies.aspx
Of course you could also keep things as they are and then monitor disk space and log volume during migration and as things rise Execute a Full backup to clear/truncate the logs. Technically its safer to do this then turn on circular logging but its
allot more resource intensive all the way around.   Another option would be to schedule several full backups during the migration process, i.e. every NN hours etc and then the backups will happen automatically and all should be well as long as the
backups complete before the disk runs out of space from log file generation
Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 -->
2007 --> 2010 --> 2013 with Lucid8's

Remnants of old Exchange server after migration

Migrated to 2010 and all is well however, the old Exchange server is still referenced in some places. The actual server itself has been decommissioned and re-purposed but has the same fqdn just is not running Exchange 2007 anymore.
How to I manually remove all aspects of the old server without interrupting services on the new 2010 server

Hi Wrangler,
Remove the Exchange 2007 server from Active Directory
a.       Launch ADSI Editor
b.      Expand to Configuration Container->CN=Configuration, DC=
Domain_Name ,DC=com->CN=Services ->CN=Microsoft Exchange->CN=
Your_Organization_Name->CN=Administrative Groups ->CN= Your_Administrative_Group_Name->CN=Servers
c.       Right-click old Exchange 2007 server object, and select “Delete”
d.      Click “Yes” in every jumped windows that prompts you to confirm the deletion

Best software for searching exchange server mailbox

hi
We have exchange server 2013 in our company and we need some report like ( our client from one date how many email send or received or sending or received from/to who ) and also what is a subject of email and what is the body of mail ).plz help me how can
i manage this searching and how can create that report. or which software i can use for that.
My manager need some report ( like number of sending email or number of received email from all client or one client in exact day or between dome date or ... ).
Thanks for your helping.

Hi,
The following scripts can help you get the number of e-mails sent and received by one user.
[Int] $intSent = $intRec = 0
Get-TransportServer | Get-MessageTrackingLog -ResultSize Unlimited -Start “08/01/2013” -End “12/23/2014” -Sender "[email protected]" | ? {$_.Source
-eq "STOREDRIVER"} | ForEach { $intSent++ }
Get-TransportServer | Get-MessageTrackingLog -ResultSize Unlimited -Start “08/01/2013” -End “12/23/2014” -Recipients "[email protected]" | ForEach {
$intRec++ }
Write-Host "E-mails sent: ", $intSent
Write-Host "E-mails received:", $intRec
To get total sent or received messages, you can look at the following scripts.
https://gallery.technet.microsoft.com/office/f2af711e-defd-476d-896e-8053aa964bc5
If you want to get the subject or body of mail, maybe you can use some scripts. I recommend you ask in the Script forum which is staffed by more experts specializing
in this kind of problems. Thanks for understanding.

Exchange 2007 - Exchange 2013 Mailbox Migration Issues

Exchange 2013 - Mail Flow is working. OWA Access is great. We have issues connecting Outlook 2010 Clients. If I create a new user and mailbox Outlook 2010 works fine. However, if we migrate a user's mailbox to the new Exchange
2013 server. Outlook Web (OWA) works and mail flow but "OUTLOOK 2010 can not connect to the new server" There is something different about a newly created account and a migrated account. Any help would be great. I did check
inheritance in AD and it was on for these accounts. This occurs with any account migrated to the new server.

1. Could you double check your Exchange 2007 Internal Autodiscover URI - it should be pointing to Exchange 2013. All clients should be receiving their autodiscover config from the Exchange 2013 server. Based on the client's mailbox location, Exchange 2013
generates and provides the correct information.
2. If the autodiscover URI is "autodiscover.yourdomain.com" and you've configured Split-Brain DNS or Pin-Point DNS zones on the local network, make sure the name is resolved to Exchange 2013 internal IP address.

Exchange 2013 mailbox migration stalled duration

I am in the process of migrating mailboxes from Exchange 2007 to 2013. The moves seem to take an awfully long time. I am migrating a batch of 10 users and the total mailbox size is 32GB. It has been running for 12 hours and is not complete. I have notice
that there is a "Stalled Duration Time" what does that represent? Also, what should I expect in terms of migration time?

Also, seeing this in the logs. It's been about 18 hours now.

Exchange 2013 mailbox migration issues

or I could just restart the 2013 mail server.... *sigh*

So Exchage 2013 is set up, sending and receiving emails is working, OWA access is working and redirecting to our old 2010 if the mailbox resides there.However after moving a mailbox from 2010 to 2013 there have been a few issues.The mailbox connects ok with Outlook 2013, but will not open the onprem Archive."cannot expand the folder. The set of folders cannot be opened. Microsoft Exchange is not available.."This works ok in OWA.I then deleted the outlook profile, but now Outlook cannot connect to create a profile at all!It detects my name and email ok, then when it gets to "logging on to the mail server" I get the error"Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this...

3rd 2010 Exchange server Mailbox Role- other 2 server don't see mailboxes

Hi
I have added a 3rd server in a Mailbox role only. the install when fine, the other 2 servers see the server, but don't see the mailbox databases on the new server. but the new server sees the new databases and the other server's databases. the other servers
read " copy status- Service down"
i'm thinking I have to something in AD...
any ideas?
thanks
The Big Lug

Hi,
Please run the get-mailboxdatabasecopystatus command on the three different MBX servers and check the output to see if there is any difference.
Did you deployed DAG in your environment? If so, I recommend you use the Test-ReplicationHealth command to check the result against this DAG. If not, please check if there is any relevant error event in the Event Viewer in the problematic Mailbox server.

New Deployment of Exchange Server 2013.

Hello All,
Good Day !!
We are planning to install Exchange 2013 Mailbox and Client Access on single server ( Windows Server 2012 Standard).
Currently Active Directory roles runs on windows server 2008R2 Sp1.
Its a new deployment for exchange as currently we are using Godaddy email server ( Can we migrate all our emails from Go daddy to our exchange Server).
Also confirm current active directory will support the installation and deployment of Exchange Server 2013.
How much HDD, RAM and CPU cores are required to support exchange Server Mailbox and Client Access roles( Users are 30 ).
How many Static IP's and SSl certificates are required for exchange.
Atlast as i said its new deployment please suggest if anything else is missing from my end.

Hello,
I recommend using professional cheat-sheet articles for Exchange 2013 sizing:
http://www.msexchange.org/articles-tutorials/exchange-server-2013/planning-architecture/exchange-2013-sizing-cheat-sheet-part1.html
http://www.msexchange.org/articles-tutorials/exchange-server-2013/planning-architecture/exchange-2013-sizing-cheat-sheet-part2.html
The server's requirements depend on many factors ie. number of emails received/sent, mailboxes sizes etc.
In addition your AD environment's level supports Exchange 2013 deployment. You will need only prepare your schema and forest for Exchange installation. You will need also at least one public IP address and SSL certificate for that server.
Hope it helps,
