Sometimes (for example, after a small disk array failure ;)) you need to resume failed and suspended database copy. We can do that with this  command: resume-mailboxdatabasecopy .

But what if there is a lot of databases ?

In this case we can use this command to resume replication for all databases on specific server:

get-mailboxdatabasecopystatus -server “server_name” | resume-mailboxdatabasecopy

Also for suspending replication we can use this command:

get-mailboxdatabasecopystatus -server “server_name” | suspend-mailboxdatabasecopy

Each administrator of the Microsoft Exchange Server had certainly met or will meet with a situation where you have to find a specific email in the mailboxes, and sometimes even remove it.

In Microsoft Exchange 2010 to search mailboxes, we can successfully use the Search-Mailbox command.

But first make sure that we can run the command Mailbox-Search and
New-MailboxImportRequest.
If you try to run the New-MailboxImportRequest and reveive the message:

 “The term ‘New-MailboxImportRequest’ is not recognized as the name of a cmdlet”

 

This means that we do not have appropriate access rights.

Giving the appropriate permissions:

In Active Directory, create a universal security group such ExchangeImportExport_Allowed

Microsoft Exchange 2010 what affects the size of the mailbox database

  By Remigiusz Szatkowski | 29/08/2012 - 21:57 | ,

The Microsoft Exchange database size depends mainly on the number and size of the mailboxes located at the mailbox database.

Size of boxes, which will be located in a given database, we can predict and control so that we know about what size will depend on our database.

Unfortunately, there is still a couple of other factors that could cause sudden expansion of the size of the database or its continued growth.
Below we will present on what you should look in the settings database.

The main parameter determining the maximum size of mailboxes in the database is Quota.
Quotas can be set at the mailbox database and then will apply to all mailboxes in the database if individual quota is set on mailbox.

The quotas can view the values and set in the Exchange Management Console in the properties of the database, we can also be changed using the PowerShell command:

Displays the current quota limits:

 Get-MailboxDatabase "MailboxDatabase" | Select *Quota*
