  One car, one driver Look at the traditional datacenter infrastructure where single application runs on a single server so if you need to run 100 applications then you will be required to implement 100 physical servers, now just think about the cost of hardware, maintenance, electricity or power consumption and day to day operations for all these applications running on single physical servers. This is analogous to a single car, single driver, where the car helps get the person from "point A" to "point B" and the single driver represents the driver and sole passenger of the vehicle. If this were a single driver on a energy-efficient motorcycle or scooter, than would be reasonable, but people often drive alone much bigger vehicles,what Jeff would call "over-provisioning". Computer Chips have increased in processing power much faster than individual applications have increased their requirements, so as a result,you have over-provisioning. Carpooling - one b...

Sometime may be you have internal & external domains configured in your organization and you don't want allow internal users to send emails outside the organization or to the public domains. You can achieve this using Microsoft Exchange Transport rules. Suppose you have all internal users in OU name "InternalMail" create a distribution group in the OU and add all internal users as member. Open up Exchange admin console " https://yourexchangeserver/ecp " and navigate to "mail flow" -> "Rules" Click the + button -> " Restrict messages by sender or recipient " In this example " extblk " is a distribution group. Added two conditions first is " the recipient is located " second is " the sender is a member of " Review the Rule mode is set to "Enforce" and leave other settings default and save the rule. You are done !

In this post I am going to discuss these two topics a bit further as this issue will impact many organisations moving to Exchange 2013 for those still running Windows XP (despite the fact it is no longer supported) seeming Exchange 2013 only supports RPC over HTTP or MAPI over HTTP (out of scope for this article). To recap what I wrote about in the previous articles 5 years ago, for RPC over HTTP(s) aka Outlook Anywhere to work on any version of the Outlook Client on the XP, the MSSTD value must match the "Common Name" on the certificate. What am I talking about? Well let me show you... The MSSTD is specified under " Only connect to proxy servers that have this principal name in their certificate " which can be found within Outlook under Account Settings, Open the Account, More Settings, Connection Tab and finally Exchange Proxy Settings. This value must match the "Common Name" of the certificate which in this example is mail.example.com as shown below nex...

System Requirements Windows 7 / Server 2008 R2 or newer is required. Windows 8 / Server 2012 or newer is required for in-place resizing ( resizevhd ) and VHDX support. Usage: Create a virtual disk Download Link:   Virtual Disk Command Line Utility makevhd [-d] vhd size [source] -d Use dynamic allocation for the virtual disk. vhd Path of the VHD file to be created. size Maximum size, in bytes, of the VHD; must be a multiple of 512. Alternatively, DVD or BD can be specified for preset sizes. If set to 0, the size of the source disk, if available, will be used. source Path of an optional source whose data will populate the new VHD. Usage: Create a differencing virtual disk makevhd -f vhd parent -f Create a differencing VHD. vhd Path of the differencing VHD file to be created. parent Path of an existing disk to be associated as the parent.

When you work with Microsoft’s Hyper-V product, you certainly come across situation where you had to carry out tasks on the attached VHD files. It has to be said the built in tools provide some basic operations, but in many cases these tools lack some features that might prove useful. One of those features is resizing the volume hosted in a VHD file. It’s probably not the most common task that you would use, but still there’s always that one odd case. As i just needed to adjust the volume within one of the VHDs, i did some research in to most efficient way of achieving this. The solution was a little utility called  VHD Resizer .  NOTE: This link has stopped working in the meantime. To download the utility, look for the download link at the end of post. You can download the installer from the link above, extract the zip file and run the installer. Once installed, you can open the utility – it will prompt you for the file you want to resize. The utility being very simple, there...

Exchange 2013 - some users can't use ActiveSync [solved, AD permissions/groups] Recently, I was at a customer reporting issues with several users not being able to synchronize their mobile devices using ActiveSync.  The customer was running Exchange 2013 CU16 and used various mobile devices, e.g. iPhones as well as Android phones and tablets. So, I dig down  Solution: When a mail box is moved from exchange 2007 to exchange 2013, Exchange Server inheritable permissions needs to be added in order for Active Sync to function. Open Active Directory Users and Computers On the menu at the top of the console, click View > Advanced Features. Locate and right-click the mailbox account in the console, and then click Properties. Click the Security tab. Click Advanced. Make sure that the check box for "Include inheritable permissions from this object's parent" is selected. If the user is a member of certain protected groups such as Domain Administrators, it is normal for this...

The first step is to check if the  Courier  IMAP server is accepting connections. Open a terminal window and type: telnet hostname 143 Replace  hostname  with the  IMAP  server's  DNS  name. This expected results would look like this: $ telnet imap.example.com 143 If you get the error "no login failed" then you need to check the following; 1. Make sure IMAP Service is running. 2.  You should make sure that you are using the correct password and that the mail username is in the format: 3. Make sure there is correct name in your exchange server certificate. Please check your certificate settings: Get-ExchangeCertificate | fl I noticed that the InternalConnectionSettings is pointed to Test2.contoso.com but the X509CertificateName is using Remote.domain.com. If there is a certificate with Test2.contoso.com, please change the X509CertificateName to it to have a try: Set-IMAPSettings -Identity Test2\1  -X509CertificateName Test2.contoso.com T...
