Exchange Sizing Calculator & Backup Configuration

I see a lot problems with to small log disks. Sizing Exchange is a very imported thing!! Today there a lot of problems with Thiry-Party Devices. They can create a lot of log files if you run a oudated Exchange Server. Transaction logs are truncated when backup software successfully backs up an Exchange server. The ‘Backup/Truncation Failure Tolerance’ field in the Backup Configuration section, allows a value to be set that specifies how much capacity will be available for logs in the event of backup failures or issues with Thirth party devices. The default value is 3 days. Change This!! This ensures that the server will continue to function and you have the ability to restore from transaction logs for x days, if the backup fails & and if some thirth party device give some trouble. Logs disk & backup should be monitored to ensure that they are successful.

Moved al mailboxen to Office 365 & Still using dirsync! Can you remove the last Exchange 2010/2013 Server. Yes It Can! Just don’t do it!! You will have a support issue when you have problems!!

After a customer migrated  to Exchange Online some time ago.
They wanted not a hybrid situation. but they are using still DirSync!

After reading: Decommissioning your Exchange 2010 servers in a Hybrid Deployment a I read its not a real problem.

Changed DirSync & After that Uninstalling Exchange 2013 was very easy.

I had only to disable the Arbitration mailboxes: I did that with the following powershell command:

Get-Mailbox -Arbitration | disable-Mailbox -arbitration -RemoveLastArbitrationMailboxAllowed

I did not publish this article because i has still some doubts!!

I had still a question: Do want to remove the last Exchange Server? Have you a supported Environment without a local Exchange Server and still using DirSync??

Yes & No!!

After reading Concerning Trends Discovered During Several Critical Escalations

Microsoft Says:
You may remove the last Exchange Server locale when you move totally to Office 365/Exchange Online, but change Exchange Attribuuts trough ADSI is not supported.

If you don’t have a third party tool for that. The only way is trough ADSI and that is not supported.

My Conclusion:

You have a support issue when you dropped a Call at Microsoft and they investigate your environment.
Don’t remove the last Exchange Server even when all mailboxen exist in Office 365/Exchange Online and keep them up to date!
You can always install a Exchange Server but most of the times it will be always to late!

Exchange & Patching!!!

Microsoft recommends adopting a software update strategy that ensures all software follows N to N-1 policy, where N is a service pack, update rollup, cumulative update, maintenance release, or whatever terminology is used by the software vendor. Microsoft strongly recommend that our customers also adopt a similar strategy with respect to hardware firmware and drivers ensuring that network cards, BIOS, and storage controllers/interfaces are kept up to date.

Software patching is not simply an issue for Microsoft software. You must also ensure that all inter-dependent solutions (e.g., Blackberry Enterprise Server, backup software, etc.) are kept up-to-date for a specific release as this ensures optimal reliability and compatibility.

Customers must also follow the software vendor’s Software Lifecycle and appropriately plan on upgrading to a supported version in the event that support for a specific version is about to expire or is already out of support.

For Exchange 2010, this means having all servers deployed with Service Pack 3 and either Rollup 7 or Rollup 8 (at the time of this writing). For Exchange 2013, this means having all servers deployed with Cumulative Update 6 or Cumulative Update 7 (at the time of this writing).

For environments that have a hybrid configuration with Office 365, the servers participating in the hybrid configuration must be running the latest version (e.g., Exchange 2010 SP3 RU8 or Exchange 2013 CU7) or the prior version (e.g., Exchange 2010 SP3 RU7 or Exchange 2013 CU6) in order to maintain and ensure compatibility with Office 365. There are some required dependencies for hybrid deployments, so it’s even more critical you keep your software up to date if you choose to go hybrid.

Exchange 2013 Managed Availabilty and why do I need 200GB free space

I  like the Managed Availability and the “self healing” aspect of Exchange 2013.
But about SpaceMonitorLowSpaceThresholdInMB is nothing about to read. 

If you check your serverhealt with:
get-serverhealth -identity servername -HealthSet Diskspace | ? AlertValue -ne unHealthy | ft -autosize

You can get lots of Databases which are in an unhealthy state because the LowLogVolumeSpaceMonitor is configured to check if you have 200 GB of free space. That would be an great idea, if you have a large organization and you have lots of disks whith a huge amount of free space. But in smaller company it would be great to change this value.

With Exchange 2013 SP1 you should now be able to configure this. Go to all of your Mailbox Servers and in regedit go to the following path:

HKLM\Software\Microsoft\ExchangeServer\v15\ActiveMonitoring\Parameters

If you have an DWORD called SpaceMonitorLowSpaceThresholdInMB then you’re lucky. If not, create a DWORD with the name and then you can change it to an Value which suits you more. But, as the dword is mentioning, its in MB not GB 😉

Updated 15-03-2015

No Reg Setting but Add-GlobalMonitoringOverride is better!!

SpaceMonitorLowSpaceThresholdInMB.ps1
write-host = “Default 175GB CU7”
$diskspace = Read-Host ‘What is the Minimum Free Disk Space in MB?’
Add-GlobalMonitoringOverride -Item Monitor –Identity MailboxSpace\StorageLogicalDriveSpaceMonitor -PropertyName MonitoringThreshold -PropertyValue $diskspace

Exchange Administrator’s toolkit

There are lots of tools for Exchange Server available, you can find most of them at the Exchange Server Wiki (some of the tools listed are for previous versions of Exchange).

Here is a short selection from the vast collection available:

Hotfix KB2899591 for Outlook 2010 add support for MAPI/HTTP

Microsoft released a hotfix  KB2899591 for Outlook 2010. This hotfix adds MAPI/http support for Outlook 2010 clients. So now can switch if you are using Exchange 2013 SP1 or later from RPC/http to MAPI/http.
See  KB2899591 for the additional fixes that are included in hotfix  as well.

You can request the hotfix for x86 and x64 versions of Outlook 2010 here.

Security update available for Exchange 2007, 2010 and 2013

Microsoft has released a fix for Outlook Web App in all supported versions of Exchange.
