Perform dial tone recovery

Hi @Андрей Михалевский,

Thanks for your response!

The -AllowFileRestore parameter is used to allow the restore process to overwrite the mailbox database. You can refer to the official Microsoft documentation here：https://learn.microsoft.com/en-us/powershell/module/exchange/set-mailboxdatabase?view=exchange-ps.

The Get-Mailbox -Database DB30 | Set-Mailbox -Database TEMPDB30 commands are specifically for user mailboxes. Public folders are managed differently. To move public folders, you need to use the New-PublicFolderMoveRequest cmdlet. Here is an example:

New-PublicFolderMoveRequest -Folders \PublicFolder1 -TargetDatabase TEMPDB30 

I deeply sympathize with the performance issues you are experiencing, such as freezes, slow updates, and errors. We can only hope that Microsoft will update and improve this product in the future. Thank you for your understanding!

Best,

Jake Zhang

Thank you very much. You've been very helpful!

@Jake Zhang-MSFT final question

When I applied dial tone, the user sees the message when they start Outlook:

Pardon my Russian. I'll translate:

Временный почтовый ящик - Temporary mailbox

Прежние данные - Previous data

Отмена - Cancel

I have to choose-- temporary mailbox

The user gets a new clean mailbox with no emails as it should be in the new TEMP base. To be able to use the service until I restore the database from backup.

I restored the base and gave it back its configuration.

The Mictosoft Exchange server administrator has made the changes, so you need to exit the Outlook program and restart it.

I restart Outlook and see the same thing as in the first picture. I select the option - Temporary mailbox

The user received their recovered data. Mail's working, everything's fine.

But every time Outlook is restarted, the client always sees a question box(first picture).

Is there something else I have to configure on the server side?

Also I have not deleted the TEMP base at this point. Could it be because of this? What should I do ?

I don't really understand why I have to select Outlook - Temporary Mailbox every time I start Outlook - Temporary Mailbox if I have reverted the original database and moved the configuration from the temporary database to the original database (Get Mailbox -Database TEMPDB30| Set-Mailbox - Database DB30).

I have 2000 users and this scenario is not very convenient. I thought it was supposed to remember the configuration choice after the first selection.

Could you please advise me, I have also done dial tone for archive bases by specifying the -archive key in get-mailbox.

How can I write a script that restores the archives as well?

foreach ($mailbox in Get-MailboxStatistics -Database TEMPDB30) { New-MailboxRestoreRequest -SourceDatabase TEMPDB30 -SourceStoreMailbox $mailbox.DisplayName -TargetMailbox $mailbox.DisplayName }

I don't understand how to complete this code. Get-MailboxStatistics does not have the -archive

In New-MailboxRestoreRequest if I specify -TargetIsArchive, all mail will be in the Archive.

I have tried checking the Archive keyword in the DisplayName property, but the restore doesn't work. How to correct?

Hi @Андрей Михалевский,

Outlook repeatedly prompts the user to choose between the temporary mailbox and the previous data, the problem you are experiencing may be due to the presence of the temporary database. Here are some steps to resolve this issue:

1. Make sure all mailboxes have been moved back to their original database.

Get-Mailbox -Database TEMPDB30 | Set-Mailbox -Database DB30 

2. Once all mailboxes have been moved back, you can safely delete the temporary database.

Remove-MailboxDatabase TEMPDB30 

3. After deleting the temporary database, users should no longer see the prompt when they restart Outlook.

To recover archive mailboxes, you need to handle them separately. Here is how you can modify the script to include archive mailboxes:

1. Use Get-Mailbox with the -Archive parameter to get the archive mailboxes.

$archiveMailboxes = Get-Mailbox -Archive 

2. Loop through each archive mailbox and create a recovery request.

foreach ($mailbox in $archiveMailboxes) {
    $archiveStats = Get-MailboxStatistics -Archive -Identity $mailbox.Identity
    foreach ($archive in $archiveStats) {
        New-MailboxRestoreRequest -SourceDatabase TEMPDB30 -SourceStoreMailbox $archive.DisplayName -TargetMailbox $mailbox.DisplayName -TargetIsArchive $true
    }
}

Here is a complete example script that handles both regular and archive mailboxes:

# Restore regular mailboxes
foreach ($mailbox in Get-MailboxStatistics -Database TEMPDB30) {
    New-MailboxRestoreRequest -SourceDatabase TEMPDB30 -SourceStoreMailbox $mailbox.DisplayName -TargetMailbox $mailbox.DisplayName
}
# Restore archive mailboxes
$archiveMailboxes = Get-Mailbox -Archive
foreach ($mailbox in $archiveMailboxes) {
    $archiveStats = Get-MailboxStatistics -Archive -Identity $mailbox.Identity
    foreach ($archive in $archiveStats) {
        New-MailboxRestoreRequest -SourceDatabase TEMPDB30 -SourceStoreMailbox $archive.DisplayName -TargetMailbox $mailbox.DisplayName -TargetIsArchive $true
    }
}

Notes:

1.Ensure all mailboxes are moved back to their original databases and remove the temporary database.

2.Use Get-Mailbox -Archive to get archive mailboxes and create restore requests for them.

Best,

Jake Zhang

@jakezhang Deleting the TEMP bases did not help. The client still sees the request to select a profile. It will be very sad if I have to recreate 2000 profiles.
