Displaying what version of Exchange your using (Enterprise or Standard) via Script

Somebody asked me this question this week and what I thought would be quite easy turned out to be a little hard. On a Exchange 2003 box there is a WMI class Exchange_Server that you can use to do this and there is a sample in the Exchange SDK here.

But this WMI class isn’t available in Exchange 2000, The PSS knowledge base offers two solutions one is based on looking for event id 1217 or 1216 in the event log and the other one is to use the Guid from the Uninstall key in the registry and they supply all the Guid's for Exchange 2000 Q296587. Unfortunately there didn’t seem to be the same information available for Exchange 2003. A check of the ExBPA which seems to be using the same method did yield all the GUID'S for Exchange 2003 as well as the SBS versions. The Exbpa actually makes quite a good scripting reference if you have a look at the “ExBPA.Config.xml” config file there’s quite a lot of good information about how they are going about retrieving various pieces of information used in this tool.

So putting this together in a script meant using the StdRegProv WMI class to connect to the registry of each server then going though the keys of the uninstall tree looking for the GUID. I combined this will a little code that queried for all the exchange servers in a domain and also grabbed the serialnumber AD property which contains the Build number and service pack of the Exchange server .And the result is the following script that will show which version of Exchange you are using (Standard, Enterprise, SBS or Eval) and what build number and service pack each server is running. I’ve posted a download copy of the script here

The code looks like

set conn = createobject("ADODB.Connection")
set com = createobject("ADODB.Command")
Set iAdRootDSE = GetObject("LDAP://RootDSE")
strNameingContext = iAdRootDSE.Get("configurationNamingContext")
Conn.Provider = "ADsDSOObject"
Conn.Open "ADs Provider"
svcQuery = "<LDAP://" & strNameingContext & ">;(objectCategory=msExchExchangeServer);name,serialNumber,distinguishedName;subtree"
Com.ActiveConnection = Conn
Com.CommandText = svcQuery
Set Rs = Com.Execute
Wscript.echo "Exchange Servers Versions"
Wscript.echo
While Not Rs.EOF
arrSerial = rs.Fields("serialNumber")
For Each Serial In arrSerial
strexserial = Serial
Next
ExVersion = getExversion(rs.fields("name"))
wscript.echo rs.fields("name") & " " & ExVersion & " " & strexserial
Rs.MoveNext
Wend
Rs.Close
Conn.Close
Set Rs = Nothing
Set Com = Nothing
Set Conn = Nothing

function getExversion(strComputer)
const HKEY_LOCAL_MACHINE = &H80000002
Set objReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\default:StdRegProv")

strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Uninstall\"
objReg.EnumKey HKEY_LOCAL_MACHINE, strKeyPath, arrSubKeys

For Each subkey In arrSubKeys
select case ucase(subkey)

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Gr...

Exporting and Uploading Mailbox Items using Exchange Web Services using the new ExportItems and UploadItems operations in Exchange 2010 SP1

Two new EWS Operations ExportItems and UploadItems where introduced in Exchange 2010 SP1 that allowed you to do a number of useful things that where previously not possible using Exchange Web Services. Any object that Exchange stores is basically a collection of properties for example a message object is a collection of Message properties, Recipient properties and Attachment properties with a few meta properties that describe the underlying storage thrown in. Normally when using EWS you can access these properties in a number of a ways eg one example is using the strongly type objects such as emailmessage that presents the underlying properties in an intuitive way that's easy to use. Another way is using Extended Properties to access the underlying properties directly. However previously in EWS there was no method to access every property of a message hence there is no way to export or import an item and maintain full fidelity of every property on that item (you could export the...

EWS-FAI Module for browsing and updating Exchange Folder Associated Items from PowerShell

Folder Associated Items are hidden Items in Exchange Mailbox folders that are commonly used to hold configuration settings for various Mailbox Clients and services that use Mailboxes. Some common examples of FAI's are Categories,OWA Signatures and WorkHours there is some more detailed documentation in the https://msdn.microsoft.com/en-us/library/cc463899(v=exchg.80).aspx protocol document. In EWS these configuration items can be accessed via the UserConfiguration operation https://msdn.microsoft.com/en-us/library/office/dd899439(v=exchg.150).aspx which will give you access to either the RoamingDictionary, XMLStream or BinaryStream data properties that holds the configuration depending on what type of FAI data is being stored. I've written a number of scripts over the years that target particular FAI's (eg this one that reads the workhours  http://gsexdev.blogspot.com.au/2015/11/finding-timezone-being-used-in-mailbox.html is a good example ) but I didn't have a gene...
