Hi all, We have Exchange 2007 SP1 and now, most users have linked mailboxes due to merge. So, where does the attribute for linked mailbox hold? in AD or Exchange database? We are going to use Dial Tone portability in case of disaster. If we have linked mailboxes, can we still use dial tone recovery? Thank you.

Hi, Why you are keeping mailbox as linked mailbox after migration, you must convert it into user mailbox then you can use it as normal mailbox restore. Please have a look of below article for conversion : http://telnetport25.wordpress.com/2008/06/10/linked-mailbox-conversion-after-migration-in-exchange-2007/Anil

It is the msExchRecipientTypeDetails attribute as Anil referenced. Unless you want to disconnect and reconnect their mailboxes, just update that attribute. All my mailboxes that I migrated cross forest came over as linked with no root cause, no orphaned security descriptors etc. I just had to resort to updating the attribute.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Thank you and so, msExchRecipientTypeDetails attribute is in the AD. After migration, we kept users as linked mailboxes and stay that way too. the question is that if we create the empty dial tone database and run move-mailbox--configurationonly and activate the dial tone database, will users in the dialtone database on the alternate server still stay as linked mailboxes? Thank you for your help.

Not sure, I'm assuming the configurationonly switch only updates the attributes below and keeps the other exchange attributes in tact. You will have to test unless someone else knows. msExchHomeServerName homeMDB homeMTA James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Can anyone share if you have such a experience? Thank you.

Can I use ADSI to change the above attributes to test one user? Thank you.

Yes that's how it's typically done.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi SGryzbowski, Sure, you could make some tests, and in my opinion, it could be test easily. per my known, the linked mailbox in the resources exchange forest, if we do some backup, and we could do the recovery for it, the linked mailbox is some mailbox which account is disabled in the resources server, and then we could linked it any account forest that we want.

Still, most users have linked mailboxes due to merge. the question is that if we create the empty dial tone database and run move-mailbox--configurationonly and activate the dial tone database, will users in the dialtone database on the alternate server still stay as linked mailboxes? Thank you for your help.

Hi SGryzbowski, In my opinion, if we move the linked mailbox to other database, it will still be a linked mailbox. If I misunderstand your issue, please tell me. Regards!

Hmm your last post got removed. You replied that the mailbox remained linked after you restored to dial tone DB, but OWA was not working. Try this set-mailbox -database (point it to the existing DB that the mailbox resides in)James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi Gavin, Thank you and it stays a linked mailbox after I run *Get-Mailbox -Database EX1\SG2\MDB2 | Move-Mailbox -ConfigurationOnly -TargetDatabase EX2\<Storage_Group_Name>\MDB2 Can I access the OWA on the EX2 after the above command?

It that doesn't work, restart the IS store, the store is likley caching stale homemdb attribute.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi James, OWA worked now on the alternate server EX2 with dial done DB and thank you. I did some tests and use Get-Mailbox –Database "EX2\SG2\MDB2" | Export-Mailbox –PSTFolderPath C:\PSTFiles to export pst files and I got pst files. Now, I ran Get-Mailbox -Database EX2\SG2\MDB2 | Move-Mailbox -ConfigurationOnly -TargetDatabase EX1\SG2\MDB2 to move to the original server EX1 Now, I tried to merge the new content on the alternate server EX2 to the server EX1. I ran Get-Mailbox –Database "EX1\SG2\MDB2" | Import-Mailbox –PSTFolderPath C:\PSTFiles1 Then I can not import pst files and the error is [2/15/2011 3:28:24 PM] [0] [test1_admt] Opening PST file.

Do you have full mailbox rights to the destination mailbox?

Hi SGyzbowski, James gave some good suggestion, any update for your issue? Regards! GavinPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.

Here are some updates: I checked and no full mailbox rights. After I assigned the rights and it worked. THANK YOU!!! Actually, when I export and got this error and I did not pay attention too. The EX1 server is the production MBX server and EX2 is the dial tone MBX server. the one user has full mailbox rights on the EX1 server, when I ran -configurationonly to move test users to the server Ex2, the full mailbox rights are not there on the server EX2. So, the full mailbox permission stays on the DB, not AD? Before I ran export-mailbox, I need to assign the user to have full mailbox rights to all mailboxes on the server EX2. How should I assign the full mailbox permission on the server EX2? Can I add this user who needs full rights to the Exchange Domain Servers? Thank you for your help.

Correct mailbox rights is an Exchange permission. However if you granted the receive-as rights on the DB the access would've preserved. This example grants the user Ayla Kol Receive As permission for mailboxes on mailbox database DB01. Ayla will be able to log on to every mailbox on that database. Add-ADPermission -Identity "DB01" -User "Ayla" -ExtendedRights Receive-As James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
