VMware Nights @ Kilby's Bar

VMware has launch a series of videos set in a bar in Silicon Valley where a bunch of IT people are talking about the transition to a software defined IT world. Videos are about 2 minutes long and just for a laugh.

Outlook 2013 OST File

Outlook 2013 introduced many improvements into the most famous e-mail client. Some of these are around Outlook data files (OSTs). By default, when Outlook 2013 is installed, a new compressed version of the OST is created. I say “compressed” because apparently Outlook compresses several data fields/values in order to reduce the size of the OST file. This new compressed version is, allegedly, up to 40% smaller than OST files created by earlier versions of Outlook. If you don’t want Outlook 2013 to create a new compressed OST file across the workstations in your environment when you upgrade your users’ Outlook client, use the Outlook Group Policy template ( Outlk15.admx ) to enable the Do not create new OST file on upgrade policy. You can find this setting under User Configuration\Administrative Templates\Microsoft Outlook 2013\Account Settings\Exchange . A big change is that when running in Cached Exchange Mode, Outlook 2013 will only cache 12 months’ worth of data from the

Removing unwanted VMware Plugin

There are times when you installed some 3rd party products or additional VMware products where a plugin is added to vSphere client. Usually when you uninstall the products the plugins should be removed from vSphere client but sometimes it doesn't work and you need to do them manually. VMware has an KB article to help you along this process VMware KB1025360

vSphere 6? 2015? Public Beta

VMware has opened up it Beta program for the public to try out the next version of vSphere. There are loads of new features to be tried and tested by us the public to help make the product better. There are a number of webinars which will go through all the new product features weekly and will be recorded. Go join the program at but be sure you have a myvmware account to be able to sign up. Please note that although the beta program is open for anyone to try the product but what you learn and see must be kept confidential as per VMware's Master Software Beta Test Agreement and Program Rules Good luck

Back up SSO for vCenter 5.5

SSO has become a very important component for vSphere environments since 5.1. I gather most people have their management servers running as VMs as well now and do either VM-level or storage arrays backups as a way to protect themselves. But as always it is nice to know how to do a manual backup and restore of just the SSO component should you ever need it. Here is the KB article published by VMware and it might be worth scripting it and have it as a scheduled task

Exchange Cmdlet Size Values

Exchange cmdlets that accept a size value support various unit prefixes such as kilobytes (KB), megabytes (MB), gigabytes (GB) or terabytes (TB). When setting a user’s mailbox quota, for example, the following two cmdlet produce the same result: Set-Mailbox “user” -ProhibitSendQuota 1024MB -UseDatabaseQuotaDefaults $False Set-Mailbox “user” -ProhibitSendQuota 1GB -UseDatabaseQuotaDefaults $False

Users Unable to Delete Oversized Messages

If for some reason you reduce the maximum message size in Exchange, be careful because your users might experience the issue below. Let’s take an example: Exchange organization is configured to allow e-mails only up to 30M B in size; Users receive e-mails over 20MB in size; Exchange organization is reconfigured to only allow e-mails only up to 20MB in size. In this scenario, users might not be able to delete the “oversized” e-mails (over 20MB) in Outlook Web App [OWA]. When using Outlook, the local copy of e-mail is deleted, but not the one in the server. Even though we can use the MessageSize parameter with the Advanced Query Syntax in Outlook, the Search-Mailbox cmdlet doesn’t support it to it is not easy for an administrator to search for these messages from Exchange. The workaround is to temporarily increase the user’s MaxSendSize and MaxReceiveSize limits and then delete the e-mail using OWA/Outlook.

congratulations on Nuno new book

I would like to congratulate Nuno on the release of his book titled "Microsoft Exchange Server 2013 High Availability" and for him to share the knowledge and experience to everyone.

All over soon XP

By April Microsoft will not official support XP but no doubt people will still want to use XP. There might come a time where you need to reinstall XP. Installing XP will be the easy bit but to download the patches/updates you might not be able to get them from Microsoft site anymore. There is a handy tool called WSUS offline update where it goes to Microsoft Update site and downloads all the patches for a specific OS. It could be XP/Vista/7/2003/2008 etc and it also support Office products as well. As the deadline for XP is coming soon it might be ideal to use this software to download all the patches/updates to be used in the future if you so happen to need to rebuild your XP machine.
