User Mailboxes Migration

Hi,
I have been reading section 2.5 of the Administration Guide. The options to migrate user mailboxes are as follow:
1. To Migrate User Mailboxes from One Messaging Server to Another While Online
2. To Move Mailboxes Using an IMAP client
3. To Move Mailboxes Using the moveuser Command
4. To Move Mailboxes Using the imsimport Command
It appears to me that all methods require both old and new mail server running during the migration. I just wonder how could both old and new mail server having a FQDN of "mail.example.com" run at the same time without problem? Or you simply turn off DNS and use only IP addresses.
Assuming you use a different name for the new and old mail server, how do I go about changing the name? For example, I can think of two cases.
1) Setup new mail server as mail.example.com
2) Change old mail server to old.example.com
3) Turn on new mail server
4) Perform migration
5) Shutdown old.example.com
-OR-
1) Setup new mail server as new.example.com
2) Perform migration
3) Shutdown old mail (mail.example.com)
4) Change new mail server to mail.example.com
Has anybody use method 3 in the above two cases? Is it the best way to migrate user mailboxes?
Thank you.

Hi,
I migrated a whole production setup successfully with folowing approach:
Assumptions
Both servers would use same hostname/IP/DNS names
there is no MX change
1. Installed the new server in a private network and connected this server to old throufg a cross cable with whatever IP/subnet
This resolves the IP conflict -- now both servers can have same IP same hostname and the old production can still be up and running
2. Dumped the ldif of users (both PAB and Usergroup from old server to new server ( db2ldif cmd with ldapmodify used )
Now the users of old server are there in the new server too -- but without mails --- and no mails transactions are happening to the new server
3. imsbackup/ imsrestore the actual mails through cross cable link
Now the new server has fully updated users as well as mails
4. Disconnect the old server and connect the new server to production network
I had a downtime for 20 min for migration of 5000 users.
Same process would follow for servers with diferent names -- but if domain names change --- you have to edit the ldif dumps first before importing --- that is simple with awk/sed/perl whatever u use
Thanks

Outlook Users connection issues after Mailbox Migration from 2007 to 2013

Hi,
We have a coexistance between Exchange 2007 SP3 and Exchange 2013 CU7. There is an issue when after migrating the user from exchange 2007 mailbox to exchange 2013, the outlook keeps on prompting for password when it is being launched. Checking the Connection
Status we found that there is a connection to the old 2007 Server and the type is Exchange Public Folder. I have migrated the public folder and checked the Mailbox of the user and found that the DefaultPublicFolderMailbox is set to the 2013 Public Folder Mailbox.
If I check my 2013 MailboxDatabase Properties, It sill shows that PublicFolderDatabase Properties is still pointing to the 2007 Public Folder Database. Any resolution on this?
Another issue is, We set outlook anywhere on the 2013 to use basic authentication, however, when users are migrated to 2013 the Outlook client changes to NTLM. even if we set the outlook to basic to make it work, it still comes back to NTLM after a while.
I did most of the resolutions online to use powershell to make changes to outlook anywhere but no luck. any suggestions is highly appreciated.
Thanks & Regards,
Arthur

Hi,
For the first problem, please check the msExchHomePublicMDB attribute for mailbox database in Exchange 2013, you can check this attribute in ADSIEdit.
If this attribute is pointing to Exchange 2007 public folder database, please set to blank. After that, please restart the information service.
And for the second question, I suggest we open a new case for this issue. In order to avoid confusion and keep track of troubleshooting steps, we usually troubleshoot one
issue per thread in order to find a resolution efficiently.
Thanks for your understanding.

Cleanup after a 2013 forklift migration...leftover non-user mailboxes on old server?

So, I did a forklift migration from 2013 RTM to 2013 SP1. Everything is great with 1 exception: Arbitration and system mailboxes still think they are on the RTM server, so I can't remove the RTM server from the environment.
I ran the powershell command to "re-home" all the user mailboxes to the SP1 server's database...it succeeded!
Because the original information store file isn't mounted on the RTM server, I can't issue a get-mailbox -arbitration | New-Moverequest -Targetdatabase
"SP1 SERVER'S DATABASE"
My question:
Wouldn't a forklift have brought the Arbitration and system mailboxes to the new SP1 server and all I have to do is run a seperate command to rehome them specifically?
Is there a better way? Can I safely recreate the Arbitration and system mailboxes on the SP1 server?
-Dane

Hi Martina, thanks for chiming in!

Creation of 'ContentSubmitters' AD group fails to resolve mailbox migration

Hello,
I am attempting to migrate a user mailbox currently located on an Exchange 2007 box, over to Exchange 2013 CU5.
After following the steps outlined as per http://support.microsoft.com/kb/2807668/en-gb, I am still seeing a Content Index State of 'Failed and Suspended' when running the Get-MailboxDatabaseCopyStatus PS cmdlet on my Exchange 2013 server.
AD has replicated correctly, and the Microsoft Exchange Search and Microsoft
Exchange Search Host Controller services have been restarted.
Can anyone help me from losing any more hair?!
Many thanks.

Hi,
Did you try recreating content index?
- Disable the CI for the database.
Set-MailboxDatabase -IndexEnabled $False
- Stop Exchange Search search on passive copies
- Rename the catalog folder on all copies
- Re-enable CI for database
Set-MailboxDatabase -IndexEnabled $True
If you still get issue after this then suggest you to post errors related to MSExchangeFastSearch from the event logs...

Mailbox migration failing after Upgrading CU5 - CU6

hello fellow readers,
we have an Exchange 2007 (latest needed Patchlevel) / Exchange 2013 CU6 Environment and are now having trouble migrating user mailboxes from the Ex2007 mailbox server to the new Ex2013 server.
migration of the first boxes before applying CU6 went fine and smooth, but now all mailbox moves are stuck with the status "Qeued".
a ps command "get-moverequeststatistics karl.treiber" brings the following
Postfach 'Karl Treiber' wird zurzeit nicht verschoben. + CategoryInfo : InvalidArgument: (karl.treiber:MoveRequestIdParameter) [Get-MoveRequestStatistics], Mana gementObjectNotFoundException + FullyQualifiedErrorId : [Server=SERVERNAME,RequestId=bf51511d-c7b8-4b39-ad60-caa71015cc6c,TimeStamp=10.11.2014 11 :27:29] [FailureCategory=Cmdlet-ManagementObjectNotFoundException] 9B1AC428,Microsoft.Exchange.Management.Recipien tTasks.GetMoveRequestStatistics + PSComputerName : SERVERNAME.DOMAIN.local
i'm guessing that this is correct, as the migration hasn't started yet. in somehow similar threads people suggest putting the BadItemLimit higher, so i tried running ps command "set-moverequest karl.treiber -baditemlimit 9999" bringing the following
ARNUNG: Wenn ein Element nicht aus der Quelldatenbank gelesen oder in die Zieldatenbank geschrieben werden kann, wird
es als beschädigt betrachtet. Wenn Sie für 'BadItemLimit' einen anderen Wert als Null angeben, fordern Sie an, dass
Exchange diese Elemente nicht in das Zielpostfach kopiert. Nach Abschluss der Verschiebung sind diese beschädigten
Elemente nicht im Zielpostfach verfügbar.
Der Vorgang konnte nicht ausgeführt werden, weil keine Objekte des Typs
'Microsoft.Exchange.MailboxReplicationService.TransactionalRequestJob' auf 'DC.DOMAIN.local' gefunden wurden.
+ CategoryInfo : NotSpecified: (:) [Set-MoveRequest], ManagementObjectNotFoundException
+ FullyQualifiedErrorId : [Server=SERVERNAME,RequestId=ab82c24b-7914-4382-8de2-34462d4993b3,TimeStamp=10.11.2014 11
:38:01] [FailureCategory=Cmdlet-ManagementObjectNotFoundException] 285DB966,Microsoft.Exchange.Management.Recipien
tTasks.SetMoveRequest
+ PSComputerName : SERVERNAME.DOMAIN.local
my guess is, that something is missing in AD - but what? DC replication is checked and working as normal. i looked up the AD object of the user, searchung for Exchange values, finding some connecting to mailbox
moves, but none similar to "Microsoft.Exchange.MailboxReplicationService.TransactionalRequestJob".
everything worked in CU5 -> after updating to CU6 we had serious issues with mailbox databases in dirty shutdown and called MS or help. as mentioned
here this was a known error and they gave us the
hotfix for that. the hotfix seemed to be so "hot" that it fixed the database problem but brought new ones, as the fix seems to not check Exchange installation path, assuming its always c:\Program Files\... (which it is not in our case).
here they suggest to run "setup /preparedomain" again, but i am worried about possible new problems.
has anyone suggestions what to check?

Hello KidStealth,
Please try the following steps:
1. Configure the database:
Get-MailboxDatabase | Set-MailboxDatabase –DataMoveReplicationConstraint None
2. We can run prepare domain, it will not cause any issue as I know.
3. Then we can try to move the mailboxes.
If issue persists, in my experience, this issue could be related to the corrupted items within the mailbox folders, so please remove the old move request, start a
new move request, use parameter “–verbose” behind the move request command, then check the detailed error message. Or we can check via command:
Get-MoveRequestStatistics -Identity “mailbox_name” –IncludeReport | fl >C:\error.txt
Please post the detailed error message. It it’s in English, I would appreciate it.
Regards, Eric Zou

Maximum number of user mailboxes supported by single Exchange Database in 2007 / 2010 & 2013 ?

What is the Maximum number of user mailboxes supported by single Exchange Database in 2007 / 2010 & 2013 ?
Aditya Mediratta

Agree with Keith, there is no MB # limit, however there are practical concerns such as DB size and how that effects recoverability as well as performance. In terms of extremes we had one major educational customer that had 35K Mailboxes in
a single database so you can utilize a ridiculous # of mailboxes in a DB if desired. IMO you are better off to keep the # of mailboxes to a reasonable level, i.e. no more than 250-500 mailboxes per DB

Free/Busy not working after mailbox migration to Exchange 2013

I'm in the process of migrating user mailboxes from Exchange 2007 to Exchange 2013
It seems that many of the users (not all) are having problems seeing free/busy once they have been migrated. If we remove the Outlook profile and recreate it, all is good. Problem is that this is happening to more and more people. Everyone
is on Outlook 2010
Test-OutlookWebServices -ClientAccessServer Ex2013 -identity MyName -MailboxCredential $cred    Results in:
Autodiscover: Outlook Provider Failure
Exchange Web Services          Failure
Availability Service           Skipped
Offline Address Book           Failure
The same if I run that command against the Exchange 2007 server.
What am I doing wrong?

I should have mentioned that. Yes, OWA works perfectly for the affected users. Just as deleting their Outlook profile and recreating a new one does.
Results of Get-WebServicesVirtualDirectory:

The URL you reference above is actually the site I used to perform migration.
What's interesting (at least to me) is that on my machine I did not have any issues with seeing calendars. The Test E-mail AutoConfiguration (without Guessmart), I get prompted for my password over and over; however, after clicking on cancel I

Mailboxes migration to new partition

Dear Folks,
We had to migrate the mailboxes from one partition to another, (partition 1 got full). We mounted another disk from SAN (600 GB) the double the size of existing partition (300 GB). How ever after the migration (mailboxes migration from old partition to new) , some how the partition size expanded, old partition was 290 GB and now after migrating the mailboxes to the newly mounted disk, partition size is 380 GB......Here is the question, How we can (OR keep the mailboxes compression) compress the mailboxes to keep the size of partition as it was in old partition (disk) ...???
We are running :
Sun Java(tm) System Messaging Server 6.2-4.03 (built Sep 22 2005)
libimta.so 6.2-4.03 (built 04:37:42, Sep 22 2005)

If the expansion has occurred due to single-message copy being expanded by the move, you can use the relinker utility to reset the hard-links between identical messages.
The theory behind single-message copy and the relinker utility are described here:

Exch2010: User mailbox changed to Shared Mailbox

[apologies for posting in the Exch 2013 section - the drop down did not show legacy exchange forum categories!]
I recently migrated from Exchange 2003 to 2010. Mailboxes were moved and showing in EMC as 'User Mailbox'. All good.
Now, two weeks later, around 10 of the 60 mailboxes are now showing as 'Shared Mailbox' and I'm not sure why, or how this changed.
There is no pattern to why some users have been converted, they are a mixed bag of staff. I have compared mailbox permissions and send as permissions with 'User Mailbox' types but can't see any difference. The users affected have not reported any issues
to me.
What would cause this to happen? I am keen to convert back to User Mailbox type but want to be sure this doesn't happen again.
Thanks

Hi,
The issue is odd. I recommend you check event log to see if there is any clues. Maybe someone converted user mailbox to shared mailbox.
When you run the Set-Mailbox -Type Shared command to convert user mailbox to shared mailbox successfully, this operation will be logged.
Open Event Viewer, locate the path: Applications and Services Logs -> MSExchange Management, check if there is related event.

Legacy vs User mailbox

I understand the difference between the two. My question is; why would some moved, 2003 mailboxes' recipient type be Legacy while others, also moved from 2003, are User Mailboxes?

Hmm well technically that shouldn't happen and;
I take it that no one converted just some of the mailboxes and forgot to do others?
All mailboxes are 100% moved to 2010?
The mailboxes were all migrated via mailbox move, i.e. you didn't by chance create a mailbox for a user on 2010 and then export to PST from 2003 and import into 2010?

How can we set Admin rights to access all user mailboxes in IMAP server exchange 2010?

Hi,
IMAP is in exchange 2010..
as per guide:
http://technet.microsoft.com/en-us/library/jj200730%28v=exchg.150%29.aspx
CSV Files for IMAP Migration Batches`
Use super-user or administrator credentials. This requires that you use an account in your IMAP messaging system that has the necessary rights to access all user mailboxes.
In the CSV file, you use the credentials for this account for each row. To learn whether your IMAP server supports this approach and how to enable it, see the documentation for your IMAP server.
How can we set Admin rights to access all user mailboxes in IMAP server exchange 2010?

Hi,
Do you mean assigning a user full access permission to all other mailboxes? If so, we can try the following command:

Mailbox migration from one server (country 1) to another server (country 2 ) ( exchange 2007)

Hi,
My exchange servers are hosted with my hosting service provider at London, i have 1000 users and each are having 3 Gig mail box size (exchange 2007) and this exchange server is part of our company network which is extended to hosting service provider. I
need to setup new exchange 2007 as part of existing exchange organisation and migrate the users from London to Singapore.
The bandwidth between our company and hosting facility 20 MB.
What is the best method to move the mailboxes from loon service provide to our company ?
I cannot do complete 3 gig mailbox migration from source to destination due to wan bandwidth limitation and time.
I can do only move the mails to local pst then migrate the mailboxes to new server and import the pst mails to exchange mailbox.
Is there any other method available ? backup and restoration ?
Please help me to provide best method for mailbox migration.

For migrating exchange mailboxes from one server to another server (across the country), the suitable approach will be to export mailboxes into pst files.
This job can be simplified even more, take the offline copy of edb file to the destination system (at Singapore) then export all mailboxes (of all sizes) from offline file to separate PST files. Then run PowerShell scripts to import the PSTs. For extracting
mailboxes from offline edb file use a stable edb converter solution that extracts mailboxes (even very large sized) & create new pst file for each of equivalent size.

Double Contacts Folder after Mailbox Migration

Here’s a new one for you… I’ve done a few Exchange 2007/2010 to 2013 migrations so far, and to my knowledge they’ve been successful… until now…
I migrated my own server from 2007 to 2013 over the weekend. Mailbox migration finished early Tuesday morning my time (Monday was a public holiday). Everything seemed to work just fine.
Yesterday (Tuesday) I noticed on my Win8.1 phone, that a large number of my contacts were missing. Digging deeper I found that my phone was missing the contacts from my main mailbox. I checked my iPad to see if the contacts were there – they
were! I figured somethings up with my Win8.1 phone, so I removed the account and readded it – same problem. I added a user to the contacts on my Win8.1 phone and sync’d it. It showed up in the iPad no problems.
I then went to Outlook and switched the pane to Folder View – I could then see two contacts folder both at the root of my mailbox. The test user was in the first folder. If I try to expand the 2<sup>nd</sup> folder, it sends outlook
into a massive loop and flickers between the two folders as if they are fighting one on one…
If however I switch the view to People – I see the two contacts folders as just fine and can look into each of them. In one of them I can see the Testuser. In the other folder I can see all my other contacts that are "missing"
But wait… it gets better still. In our office several months back, we migrated from Exchange 2010 to 2013. I wondered if others had seen the problem. From what I can see today, it appears that anyone with a Windows 8 phone has this duplicated
contacts folder. They appear to have the exact same problem… right down to the flickering and crash of Outlook 2013…
I'm concerned now because this is now a couple of migrations that we've seen this on and I've no idea whats gone wrong.
I've checked event logs - nothing seems amiss there.
Any thoughts on how to troubleshoot this?

Wayne Small

Hi Wayne,
I have seen this issue if original mailbox was in different language than the new mailbox.I have even seen this even if original mailbox had EN-US and new database is EN-UK.
Please run the following command in Exchange powershell:
Get-MailboxFolderStatistics [email protected] | Select Name,FolderSize,ItemsinFolder
Do you see two contact folder here aswell?
Solution for us it to copy all "old Contacts" to new Contact and delete the old one.When try to delete the default Contact you will get error message that it cant be removed.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you. Thank you! Off2work

Move user Mailbox using EMC 2013

how can move a user Mailbox from one database to another database on the same Mailbox Server 2013 using the EMC. Have not been able to complete move with the ECP?

Hi Ronald,
I recommend you refer to the thread Jatin provided to do the migration in Exchange 2013 EAC. After the migration, you can use the Get-Mailbox bob1 | fl Name,ServerName,MailboxMove* cmdlet to verify the move status.
If the migration fails, please take your time to post the error information for my further research.
Hope this can be helpful to you.
