Bulk Enable Exchange 2013 Users

Have you ever needed to enable several users at once in Exchange 2013?

The Following PowerShell script will do just that.

Simply modify it to point to your OU with you users in, and enter the Database you wish to use.

Get-User -RecipientTypeDetails User -OrganizationalUnit “plexuk.co.uk/LDA/Users/Support” | Enable-Mailbox -Database LDA_MBX1

 

Fix for Exchange 2013 OWA Web Apps not working

There’s a quick fix available when your Web Apps are not working on Exchange 2013 OWA when it’s installed on Windows 2012 or Windows 2012 R2.

If your Web Apps show this behaviour:

01_web_apps

Then here’s a quick fix:
On your Exchange 2013 Frontend server find the “<exchange>FrontEnd\HttpProxy\owa” folder and open web.config in notepad.
Find “<appSettings>” and directly after that add

<add key=”aspnet:UseLegacyRequestUrlGeneration” value=”true” />

This tells IIS to generate “@” instead of “%40″ in the urls requested by the Web Apps, which, as it turns out, is the problem when you see the behavior described above.
Save the web.config file and restart IIS.

How to Exclude a Mailbox Database from Automatic Mailbox Provisioning

Exchange Server 2010 and above includes a new feature that can automatically load balance the provisioning of new mailboxes across multiple mailbox databases.  Although the Exchange administrator can still specify a mailbox database if they want to, it is no longer mandatory and the Exchange server can make the decision as to where to provision the new mailbox instead.

Despite the benefits there are also situations in which the Exchange administrator would not want mailboxes automatically provisioned on a particular database.

To exclude a specific Exchange Server mailbox database from automatic provisioning use the following command in the Exchange Management Shell.

[PS] C:\>Set-MailboxDatabase -Identity "Mailbox Database 04" -IsExcludedFromProvisioning $true

To re-enable the mailbox database for automatic provisioning set the value back to $false.

[PS] C:\>Set-MailboxDatabase -Identity "Mailbox Database 04" -IsExcludedFromProvisioning $false

How Exchange server uses transaction logs

If you have ever wondered why Exchange uses Transaction Logs read on.
The Transaction Logs are an important part of Exchange Server, and are used to store data before it is written to the Database. The Transaction Logs allows uses to send / receive emails, without needing to touch the database thanks to the write-ahead method of logging.
When a message is sent, the transaction is first recorded in the transaction logs. Until the transaction is committed to the Exchange database (EDB), the only existence of this data is in the system memory and the transaction logs. In the event of a crash, you lose the contents of the memory and all you are left with is the record in the transaction log. These transaction logs are crucial to the recovery of a failed Exchange server, whether it was a minor crash that required a reboot, or a more catastrophic failure requiring the deployment of your disaster recovery plans. The same goes for other transactions such as received messages, deleted items and messages moved to different folders. For this reason, it is recommended to house the transaction files on a redundant storage system, like a RAID 1 array, so that in the event of a hardware failure, no data is lost. Losing a set of transaction logs will not prevent you from restoring from your backups, but you will lose all the messages and changes since the last full backup.
