August 16, 2010 Leave a comment

have you ever wanted to reduce the VHD size or resize it to a newer size, here is a step by step on how to resize the VHD disk size:

1- you need to shrink the VHD disk first:

a: If your Host is running Windows 2008 R2, then you can attach the VHD directly to the host and then use disk management to shrink the VM. Once done detach and run resizer. This attach VHD option is also available in Windows 7.

b: If you don’t have a Vista/2008/Win7/2008 R2 VM and you host is Windows 2008 (not R2), you can install VHDmount tool available in Virtual Server 2005 R2 SP1 setup and use it to mount the VHD and then use the disk management tools to shrink the VHD.
Mount a VHD file with VHDMount

Once you did shrink to the VM, do resize using VHD sizer :

#Exchange Calls to UM or Voice Mail are dropped when the called is withheld

August 7, 2010 Leave a comment

That is an issue with Exchange 2007 and 2010 as well, if the call is withheld then the call is dropped, this is basically because the the call to the Exchange voice mail when the number is withheld unknown the calls comes in the format sip@withheld or sip@unknown thus the call is dropped, there is currently no available official fix for this issue from MS, to workaround this issue you might want to look into your gateway of your PBX to create some sort of call modification rule to convert unknown to some thing like 1unknown or 0withheld just add any number before this text thus the call comes in the format sip@1unknown or sip@1withheld and thus Exchange 2010 accepts it.

#Exchange users accessing ECP or options in OWA gives getting error Outlook Web Access is requiring Outlook Live to change Options

August 5, 2010 Leave a comment

Scenario:

a user is accessing OWA on Exchange 2010 server, he can access OWA fine, once he clicks on the options button or trying to access the ECP virtual directory the user gets the following error:

Outlook Web Access is requiring Outlook Live to change Options

Cause and Solution:

This is caused by 2 reasons:

– Either wrong authentication configuration on the ECP virtual directory, to solve it remove the ecp virtual directory using remove-ecpvirtualdirectory and new-ecpvirtualdirectory.

– Make sure that the user accessing the options page have already a mailbox and that he is not just user who has a permissions to access the mailbox.
