Can’t activate Exchange Server – Use this Exchange Powershell command to activate your Exchange Server

Posted on by David Florey

I recently had an issue where through ECP I was unable to activate a new Exchange server 2019 I was building. I believe my issue may have been I was logged into the ECP of an older Exchange (2016) server as the 2019 server’s ECP wasn’t yet accessible.

In any case, you can use this command to activate Exchange servers from the Exchange Powershell:

Set-ExchangeServer -Identity MyNewExchangeServer -ProductKey 12345-12345-12345-12345-12345

Once this has been successfully issued, you will need to restart the Microsoft Exchange Information Store service.

 

Restrict High Memory Usage by Information Store on Exchange 2007 / 2010 (also SBS 2008 / 2011)

Posted on by David Florey

Scope:

Microsoft Exchange Server 2007 and Microsoft Exchange Server 2010 (in conjuncion with Active Directory), or Microsoft Small Business Server 2008 / 2011.

Issue:

Microsoft Exchange Information Store (store.exe) consuming excessive amounts of system memory, often causing the server performance to take a significant hit.

Solution:

On the domain controller, open ADSI Edit (adsiedit.msc)

Connect to Well Known Name Context: Configuration

Drill into: Configuration > Services > Microsoft Exchange > [domainName] > Administrative Groups > Exchange Administrative Group > Servers > [serverName]

Right click on the server name and right click Information Store, then go to Properties

In the properties window, scroll down to the two attributes:

  • msExchESEParamCacheSizeMax
  • msExchESEParamCacheSizeMin

By default, the values of both are <not set>

We need to set values for both, if you only set values for the Max, then without the Min, the setting will not take place.

For Exchange 2007 (SBS 2008):

  • 1GB – 131072
  • 2Gb – 262144
  • 4Gb – 524288
  • 6Gb – 786432
  • 8Gb – 1048576

For Exchange 2010 (SBS 2011):

  • 1Gb – 32768
  • 4Gb – 131072
  • 6Gb – 196608
  • 8Gb – 262144
  • 12Gb – 393216

Note that Exchange 2007 uses a page size of 8KB and Exchange 2010 uses a page size of 32KB (hence the differing values).

Restart (or schedule restart) the Exchange server once the values have been applied.

Notes:

Although this solution is documented by Microsoft its not a supported configuration.

Don’t set the Max values too small otherwise your mailbox store may run into other issues and if too small, will cause more disk paging instead.
