Last year I was invited to write an Exchange 2016 book with a few fellow MVPs. Unfortunately, due to unforeseen circumstances, the book was later cancelled.

Rather than have my chapters go to waste (combined these chapters are 40,000 words) I wanted to offer them to you for free.

Below you will find three chapters covering the management of mailboxes, groups, contacts, mail-enabled users, and public folders.

That said I do want to warn you that these chapters only received a brief technical review. They did not go through any formal editorial process, so I apologize in advance for any errors. Please read these at your own risk.

While I offer these for free I would like to state that my work is under copyright. By viewing or downloading these chapters you agree to the copyright notice below.

I have always been a big fan of dark mode for any application as I spend more hours than I care to admit at my computer, so eye strain is always a concern.

Dark mode lets us protect our eyeballs from the harsh glare of a white screen, and it may just conserve a little more battery life on our mobile devices.

Microsoft Teams has such a mode.

Enabling dark mode

To enable dark mode, log onto Microsoft Teams and select your profile picture in the top right of the window. From the context menu click Settings.

Microsoft hosted its annual Ignite conference in Orlando this September. Ignite was massive at 1,610 sessions. That is a lot of sessions! For the first time ever, Microsoft live streamed most of its sessions. Not just the keynotes! You can find the on-demand sessions at the Microsoft Tech Community. Here are the top 15 sessions I think every Exchange admin should watch.

Tip: I have included extensive notes for each session and the time each topic starts. You can expand the session notes under each video by clicking “Show more session notes”

Welcome to Exchange Server 2019
In this session, Greg Taylor and Brent Alinger discuss all the new features shipping in Exchange 2019. They also discuss features that have been discontinued and the system requirements for Exchange 2019.

Current state of Exchange Online (1:05 mins)
- Office 365 revenue 38% YoY growth
- Office 365 seats 29% YoY growth
- 135 million users in Office 365

- Exchange on-prem code moved to its own code branch & will be independent of Exchange online
- Discussion on cumulative update schedule going forward
Unified Messaging removed from Exchange 2019 (10:40 mins)
- UM functions have been removed
- Migrating a UM-enabled mailbox to Exchange 2019 will UM-disable that mailbox
- Recommend replacement is Cloud Voice Mail which can still store voice mail in Exchange mailboxes via EWS or SMTP
- If you need Unified Messaging:
  - Move all mailboxes to Office 365
  - Migrate to Skype for Business Server 2019 & utilize Cloud Voice Mail
  - Stay on Exchange 2016
  - Deploy a 3rd party voice mail solution
- For more information see BRK3229 – Everything you need to know about Skype for Business Server
Unified Messaging Migration scenarios for Exchange 2019 (15:30 mins)
- Exchange 2013 or 2016 + Skype for Business
  - Migrate to Skype for Business Server 2019
  - Enable Cloud Voice Mail
  - Migrate to Exchange Server 2019
- Exchange 2013 or Exchange 2016 + 3rd Party PBX
  - Implement a 3rd party voice mail solution
  - Migrate to Exchange Server 2019
- Note: Due to the discontinuation of Session Border Controllers, 3rd party PBX systems cannot use Cloud Voice Mail.
Vision for Exchange 2019 (17:30 mins)
Exchange Server 2019 requires Windows Server 2019 (19:20 mins)
- Windows Server 2019 available in October
Exchange Server 2019 supports Server Core (20:15 mins)
- Microsoft recommends server core for improved performance, smaller attack surface & smaller disk footprint.
- Exchange 2019 can still be installed on an OS with a GUI.
Exchange 2019 will only use TLS 1.2 (23:15 mins)
- RC2, RC4, DES, 3DES, MD5 & SHA disabled during install
- Preference for elliptic curve key exchange
- Exchange will use forward key secrecy
- EHLO Blog: Getting ready for TLS 1.2
Exchange RAM requirements (25:55 mins)
- Max supported RAM = 256 GB
- Mailbox role min RAM = 128 GB (2016 was 8 GB)
- Edge role min. RAM = 64 GB (2016 was 8 GB)
- Max processor count = 48 cores (2016 was 24)
Search changes in Exchange 2019 (29:35 mins)
- Big Funnel (powered by Bing technology) replaces Fast Search
- Indexes now stored in the DBs (in each mailbox)
- No more potentially huge index files that can become unhealthy
- Index health no longer an issue for DB failovers or switchovers
- DB log shipping includes the indexes
- Outlook 2019 in cached mode will attempt to pull search results from the server (not locally)
- For more information see – BRK3130 Email search in a flash! Accelerating Exchange 2019 with SSDs (notes and session below)
Storage (and MCDB) in Exchange 2019 (32:50 mins)
- Exchange 2019 can optionally leverage a MetaCache Database (“MCDB”) which is stored on SSD
- MCDB allows for:
  - Faster logons
  - Faster search
  - Faster retrieval of very small items
- MCDB caches 10% of key data from a DB including:
  - Index data
  - Mailbox folder structure
  - Very small items
- If the SSD or MCDB were to fail all requests will be served directly from the mailbox DB on the spindle disk
- Sizing for MCDB
  - Regardless of whether you deploy MCDB or not, your spindles must always meet the IOPS requirements for your users
  - All servers must have the same spindle & SSD layout
  - Spindle disk to SSD should be 3:1
  - To plan for SSD storage take 5-6% of your total spindle storage
  - Brent’s example
    - 15 spindle disks = 5 SSDs
    - 15 spindle disks at 10 TB each = 150 TB of mailbox storage
    - 5-6% of 150 TB = 10 TB of total MCDB storage
    - 10 TB = 5 SSDs at 2 TB each
Code optimizations (45:00 mins)
- No more UM code
- No more UM language packs to install
- Exchange 2019 DVD size reduced by 20%
- This results in:
  - Faster installs
  - Fewer files and disk usage
  - Improved security
  - Reduced surface area
Dynamic Database Cache (46:25 mins)
- Memory allocation between active & passive DB copies optimized
- Active copies get more memory and cache than passive copies
Performance gains from MCDB & Dynamic Database Cache (49:30 mins)
- 20% more users per server
- Latency cut by 50% for many client/server operations
Client Access Rules in Exchange 2019 (51:15 mins)
- This restricts who can access the Exchange Admin Center & Exchange Management Shell
  - For example, allows the Exchange Admin Center to be restricted externally
- Exchange 2019 should be the front-end for all client communications
- Administrator mailboxes must be on Exchange 2019 to leverage these rules
Remove-CalendarEvents (54:10 mins)
- Exchange administrators can cancel meetings (not appointments).
- This is particularly useful to cancel a meeting from an organizer who has left the company
Outlook default option for recurring meetings now configures an end-date rather than no-end-date (57:00 mins)
Do Not Forward Meetings (57:20 mins)
- Do Not Forward can now be set on meetings created in OWA.
- Meeting attendees in OWA will see a banner stating Do Not Forward is enabled & Forward option is greyed out in the menu.
- Exchange transport enforces the Do Not Forward settings so all Outlook clients honor this setting
- All other Outlook clients will receive an NDR if they attempt to forward a Do Not Forward meeting
New Out of Office (OOF) options in OWA (1:00:20 mins)
- Automatically decline meeting invites received during the OOF
- Clear existing meetings during the OOF
- Mark the user’s calendar as blocked during the OOF

Exchange 2019 Public Preview Released

July 31, 2018 By Gareth Gudger 3 Comments

34 Shares

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

Intelligent Do Not Disturb in Outlook mobile app

July 21, 2018 By Gareth Gudger 21 Comments

40 Shares

Do not disturb in the Outlook mobile app is an amazing option. In fact, Microsoft CEO Satya Nadella recently demonstrated this functionality during his keynote at Microsoft Inspire 2018.

With Outlook mobile you have two great options when it comes to setting do not disturb. You can either set do not disturb globally across all email accounts, or, you can set it individually for each email account. The former is a great solution when you need general quiet time from all your email accounts. The latter might be better when you need to dedicate time between work and personal accounts.

For example, you could set do not disturb on personal email during business hours and, do not disturb on work email during weekends. In this article, we are going to implement this very example.

Setting Do Not Disturb

Open your Outlook mobile app and select the Waffle menu.

Make sure the email account you want to set the do not disturb on is active. You can verify which email account is active by the title in the menu. In the screenshot below we can see our work account gareth@supertekboy.com is active.

Select the Do not disturb ( ) icon in the top right-hand corner of the menu.

Pro Tip: If you want to set a blanket do not disturb across all accounts, select the Home icon. This will select All Accounts. Then select the Do not disturb (

) icon.

Cumulative Update cannot find EnterpriseServiceEndpointsConfig.xml

July 7, 2018 By Gareth Gudger 2 Comments

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

24 Shares

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
