Last week Microsoft announced the public preview of Exchange 2019. It is expected that Exchange 2019 will ship later this year.

You can download the preview bits using the link below. Please note, that this is preview code and you should not deploy this in production.

Exchange 2019 Public Preview

Server Core supported for Exchange 2019

The biggest announcement is that Exchange 2019 is the first version of Exchange to work on Windows Server Core. The benefit of Server Core is added security. Server core reduces your attack footprint and a smaller footprint means fewer things to secure and keep up to date.

It’s worth noting that from an administrative standpoint Server Core is a bit of a different animal. If you access Server Core via a console or remote session you are only going to see a command line. You will quickly notice that programs which use an MMC, such as Services or Event Viewer, are unavailable. In addition, shell programs such as Windows Explorer, or, Task Manager are also unavailable.

For Exchange, this is not much of an issue because the Exchange Admin Center and Exchange Management Shell can be run remotely from anywhere. For everything else, you will need to use Remote Server Administration Tools or remote PowerShell. For a list of tools that are directly accessible on Server Core check out the article: What is the Server Core installation option in Windows Server?

For a great write-up on installing Exchange 2019 on Windows Server Core, check out this article from the Exchange Team.

Of course, if you prefer to have the full desktop experience you can still install Exchange 2019 on a server with a GUI. [Read more…] about Exchange 2019 Public Preview Released

Cumulative Update cannot find EnterpriseServiceEndpointsConfig.xml

While applying a cumulative update I ran across the following error.

Warning:
An unexpected error has occurred and a Watson dump is being generated: Could not find a part of the path 'C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml'.

The Exchange setup log essentially repeated this same error, without any additional clues. The C:\Windows\Temp\ExchangeSetup\ folder is a staging area used by setup to unpack temporary files. These files are copied to this temporary location during the ‘Initializing Setup’ and ‘Copying Files’ steps.

When navigating to this folder it became apparent that not only was the file in question missing but the entire parent folder too. [Read more…] about Cumulative Update cannot find EnterpriseServiceEndpointsConfig.xml

Exchange Cumulative Update hangs during setup finalization

July 7, 2018 By Gareth Gudger 1 Comment

When performing a cumulative update on Exchange 2013 I ran into an issue where the finalization step was hanging as 45%.

When I checked the Exchange Setup logs I saw the following repeated over and over.

Service  'MSExchangePOP3BE' failed to reach status 'Running'  on this server after waiting for '25000' milliseconds.
[WARNING] Service checkpoint has not progressed. Previous checkpoint='0'- Current checkpoint='0'.
Previous service status query time is '7/5/2018 1:35:37 AM'.
Current service status query time is '7/5/2018 1:36:02 AM'.
Will wait '25000' milliseconds for the service 'MSExchangePOP3BE' to reach status 'Running'.

In this instance, the Exchange setup was unable to start the POP3 backend service. Attempting to start the service manually through the Services MMC also failed. Upon checking the System Event Log the following error was reported.

The address is already in use. Binding: 0.0.0.0:9955.

This error indicates something else was already listening on port 9955, which was preventing the POP3 backend service from starting (and setup from completing). [Read more…] about Exchange Cumulative Update hangs during setup finalization

Web Management Service (WMSvc) could not be started: 2147483640

While upgrading an Exchange 2013 server to the latest cumulative update, I ran into the following error while setup was configuring prerequisites.

Service 'WMSVC' failed to reach status 'Running' on this server.

When attempting to start the service manually via the Services MMC, it refused to start, resulting in the following error.

Windows could not start the Web Management Service on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code -217483640.

When reviewing the System Event Log an equally cryptic error was displayed.

The Web Management Service service terminated with the following service-specific error: Unspecified error

Exchange June 2018 Updates

Today was a big day for Exchange updates. Not only did we get Cumulative Update 10 for Exchange 2016, but we also got Cumulative Update 21 for Exchange 2013. Exchange 2010 also receives a critical update in rollup 22.

As always, test these updates in a lab first! I recommend checking out this 7-part guide on configuring Exchange in your lab. It doesn’t take much to get one going.

The updates are as follows:

Exchange 2016 Cumulative Update 10 | KB4099852 | UM Language Pack

Exchange 2013 Cumulative Update 21 | KB4099855 | UM Language Pack

Exchange 2010 SP3 Rollup 22 | KB4295699

Exchange 2013 enters extended support

In case you missed it Exchange 2013 entered into extended support on April 10th. Cumulative Update 21 is the last planned update for Exchange 2013 and no further product development is expected. Any cumulative update after 21 is at Microsoft’s discretion. However, security and timezone updates will continue to be available until April 11th, 2023, delivered primarily through the Windows Update Catalog.

As a reminder, Exchange 2010 has less than 18 months of extended support remaining. After January 10th 2020, no further technical support or updates will be available. This includes security, bug and time zone updates. If you are still on 2010, I would recommend planning a migration to Exchange 2016 or Office 365 as soon as possible.

So, what’s new in these Cumulative Updates?

One prerequisite change is the need to install Visual C++ 2013. This is required for a third party software component–that manages WebReady document viewing and data loss prevention–which ships in these updates. Visual C++ 2012 was the previous requirement for older cumulative updates. However, Visual C++ 2012 was installed automatically by the Unified Communication Management Agent (another Exchange prerequisite), so it never required administrator intervention. This means Visual C++ 2013 will also be a requirement for new server installations.

Exchange 2010 received a significant update in this release, which is the ability to leverage Windows 2016 domain controllers and global catalog servers. While 2016 DCs could exist in an Exchange 2010 environment, Exchange 2010 would simply not use them. With this update, 2010 will now leverage 2016 domain controllers and allow for the domain and forest functional levels to be raised to Windows Server 2016. This will allow you to eliminate all older domain controllers.

These updates contain a lot of security and bug fixes. Aside from the May 8th security update each cumulative update includes time zone updates and a dozen bug fixes. Check the appropriate KB article above for a list of issues each update resolves. [Read more…] about Exchange June 2018 Updates

Nullable object must have a value (when migrating mailboxes)

When migrating mailboxes between Exchange versions using the Exchange Admin Center you may receive the error:

Nullable object must have a value.

This error will appear when you navigate to the Recipient > Migration tab and click View Details on a migration batch. In the screenshot below we are examining a migration batch named “Test Migration to Exchange 2016” which contains two users. We are attempting to move these two users from Exchange 2013 to Exchange 2016.

From this screenshot, you will notice the Status column reports both users as successfully migrated. However, the Data Migrated and Migration Rate attributes in the right-hand pane are missing values. For an executed migration batch these attributes should contain metrics.

On May 4th I had the great pleasure of being a guest on the RunAs Radio podcast. I joined host Richard Campbell to discuss the latest in Exchange and Office 365. We also discuss the deciding factors and roadblocks companies face when exploring the cloud.

It was great to be back on Richard’s show. We couldn’t believe our last recording together was one and a half years ago. Boy–time flies!

Exchange Server – There was a problem loading your options (“add-ins”)

May 18, 2018 By Gareth Gudger Leave a Comment

When upgrading to Exchange 2016 you may receive the errors, “There was a problem loading your options” & “Exchange Server doesn’t support the requested version”.

Both of these errors are centered around the add-ins feature.

What are add-ins?

First introduced in Exchange 2013, add-ins are apps that you can globally distribute to all your Outlook clients, whether they be the full Outlook client, Outlook Web App, or, Outlook for iOS and Android.

Add-ins include features such as Bing Maps, which will identify an address in an email and automatically load a web-part displaying a map. Or, simply the ability to identify action items within an email.

Exchange ships with a few add-ins out of the box. Additional add-ins can be downloaded through the Microsoft store or uploaded via a custom XML file.

The real beauty of an add-in is that you can centrally manage it via the Exchange Admin Center. Much easier than deploying Outlook add-ins with traditional endpoint management software. Plus it ensures everyone is always using the latest version of an app.

There was a problem loading your options (“add-ins”)

While in coexistence with an older version of Exchange your users may receive the error “There was a problem loading your options”. They receive this error when trying to manage their add-ins via Outlook Web App. This error prevents the users from seeing or managing their add-ins.
