Mailbox Delegation in Office 365 for Small Business

The Small Business plans do not explicitly provide access to the EAC.  But you can do this by appending the correct EAC URL in your browser:

OWA 2010 Website Is Blank

After you install update rollups on Exchange 2010 it is common to get a blank white OWA page when browsing to the OWA page.


the URL will show something like the following "https://mail.mydomain.com/owa/auth/logon.aspx?url=https://mail.mydomain.com/owa/&reason=0 ."

To fix this issue you must run the Exchange Management Shell and execute the updatecas.ps1 command from the "C:\Program Files\Microsoft\Exchange Server\V14\Bin" folder. This will fix your issue, it causes the owa install to complete correctly.

This is primarily for Exchange 2007, but should work in newer versions also.

Mailbox size or item count can have a serious effect on the performance you see in Outlook. The following article gives some good insight into why, and what can be done about it.

Exchange 2007 Transport Service Not Starting

I found the following error in the Application Event Log

Topology discovery failed, error 0x80040a02 (DSC_E_NO_SUITABLE_CDC)

The fix was to reenable IPv6 on the server's NIC.

Other fixes, some of which are NOT best practice so are used at your own discretion, are available here:

Find A Specific Email Address in Exchange

Sometimes we want to know what mailbox is associated with a particular email address. Here is the easy way to find out.

Exchange 2003
For Exchange 2003, Neil Hobson writes a very good article on www.msexchange.org that makes the process very simple. You must be logged onto a PC or server that has both Active Directory tools and Exchange 2003 management tools installed. See the full article at http://www.msexchange.org/articles/finding-duplicate-smtp-addresses.html

One thing he doesn't specifically mention is that you can use wildcards, such as '*', in your search, which is handy when you don't know the exact address you're looking for.

Exchange 2007/2010
For newer versions of Exchange, simply open the Exchange Management Shell on your mail server and type the following command:

get-recipient emailaddress@domain.com

Add an Exchange Mailbox for an Existing Active Directory User

If you have a user in Active Directory that does not have an email address or Exchange Mailbox, you need to do the following to set them up.

These instructions are valid for Exchange 2007 or 2010. Ensure you are a member of the Exchange Recipient Administrators group within Active Directory. If you cannot set this up yourself, ask your network administrator to do this.

If you have a 64-bit version of Windows Vista or 7, you can have the Exchange Management Console (EMC) installed directly on your PC. How to do this is not covered in this post however. If you don't already have the EMC on your PC, to complete the following steps you will need to log onto one of your Exchange servers or another PC or server that has the EMC installed.

Once logged onto a PC or server that has the EMC installed:

1. Go to Start | All Programs | Microsoft Exchange | Exchange Management Console 
2. Once that opens, navigate to Recipient Configuration | Mailbox
3. Then on the right click New Mailbox
4. Ensure User Mailbox is selected and click Next
5. Select Existing User and click the Add button
6. Find the new user, select them and click OK
7. Click Next
8. Tick Specify the mailbox… (for Exchange 2010) or Mailbox Database (for Exchange 2007) and click Browse  
9. Select the database (there may only be one if you have a small Exchange environment) and click OK  
10. Click Next 
11. At the final page, click New to proceed with the mailbox creation

Your user should now have a new mailbox. Well done!
