Outlook 2016

22 Feb

Issue: Outlook 2016 (which I am testing) cannot connect to Office 365 Exchange.

It is no longer possible to manually enter Exchange Server details. A valid Autodiscovery record is required. Use this site to find out which autodiscovery mechanism you are using.

Verifies that we do have a valid autodiscovery record and that we use the HTTP Redirect method. It also shows that Outlook tries several other autodiscovery methods before the correct (for my organisation) HTTP redirect method.

Solution

What is actually happening is that Outlook 2016 on the PC is hanging when performing the HTTPsAutoDiscoverDomain method. We can force it to use the correct method by the following registry entries.

If Outlook is slow finding the autodiscover records, you may need to tell Outlook to exclude the root domain or other records.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\AutoDiscover\
DWORD: ExcludeHttpsRootDomain
Value: 1

The other records you can exclude, also under the Autodiscover key are as follows. Use a value of 1 to enable, delete the key if you no longer want to exclude these checks.

DWORD: ExcludeScpLookup
DWORD: ExcludeHttpsAutoDiscoverDomain
DWORD: ExcludeHttpRedirect //I DON’T EXCLUDE THIS ONE BECAUSE I USE IT
DWORD: ExcludeSrvRecord

.local again!

1 Dec

Full credit to Mark Parris for the original write up

Active Directory: .local domain design and Office 365.

Active Directory: .local domain design and Office 365.

Microsoft since the release of Windows 2000 Server have recommended that any Windows Server environment promoted to host an Active Directory forest/domain should be configured with a registered Top Level Domain (TLD), such as .com, .net, .org etc.

Many companies have ignored this advice and taken the approach of, my internet presence is for example markparris.net so I will therefore call my Active Directory forest markparris.local.

This approach to the .local namespace in Active Directory has caused no real issue, with exception of Apple Mac Integration into the environment (see below).

With the onset of the cloud, premises and off premises computing the .localnamespace now causes a potential issue. The .local namespace issue may be resolved with a simple fix or it could involve a fair amount of remediation work.

In order to use Microsoft Office 365 Cloud Services with an on premise Active Directory synchronised via DirSync to the “Microsoft Cloud” the forests namespace or to be more precise the users UPN (User Principal Name) must be an internet registered TLD.   In most companies this can be easily achieved by setting all cloud users UPN’s to their email address (or another registered namespace) and then this is what the user presents to Microsoft, to be authenticated/validated.

In some companies, the .local UPN namespace may already be in use for something else and a UPN remediation project may need to be completed prior to any Microsoft cloud integration. This could again be a simple resolution or a huge global project.

So to summarise, the recommendation is still not to use the .local namespace in any new Active Directory implementation, if you have utilised the .localnamespace and you have a requirement to implement Office 365, then identify and configure a registered UPN for the affected accounts.

To be fair to Microsoft, they did tell you.

DNS name registration with an Internet registrar

We recommend that you register DNS names for the top-most internal and external DNS namespaces with an Internet registrar. This includes the forest root domain of any Active Directory forests unless such names are sub-domains of DNS names that are registered by your organization name (For example, the forest root domain “corp.example.com” is a sub-domain of an internal “example.com.” namespace.) Article ID: 300684 – Last Review: February 16, 2011 – Revision: 25.1.  http://support.microsoft.com/kb/300684

As I put my thoughts down, it has also become apparent to me that anyone with an Active Directory namespace that uses a TLD namespace that is not registered to them will also have this same issue and will also need to configure new UPN’s.

Azure/Dir Sync

2 Nov

Sometimes you want to run a manual sync of your Azure/Dir Sync tool, you can do this via powershell using the following command;

 

Start-ADSyncSyncCycle -PolicyType Delta

Connect to Office365 Powershell

14 Apr

So you may have noticed the incredible new feature that Microsoft have rolled out to your Office 365 tenancy called “clutter”

Pain in the ass.

To disable it and to carry out many of useful admin tasks you can connect to your hosted exchange online using the following instructions – Note Im using Win10 on VMWARE Fusion

 

Open powershell as administrator

Connect PowerShell to Exchange Online

I always recommend running PowerShell as an administrator. To do that, right click on the PowerShell icon and select Run As Administrator from the context menu.

PowerShell Run As Adminstrator

First we need to set the execution policy.

 C:\> Set-ExecutionPolicy RemoteSigned

Next we need to store our Office 365 credentials in a variable. Type the command below and hit enter.

 C:\> $UserCredential = Get-Credential

A dialog box will appear. Type in your Office 365 credentials and click Ok.

Exchange Online PowerShell Credential Variable

The account you use will need permissions to Exchange Online. By default only Global Administrators in Office 365 have Organization Management rights in Exchange Online.

Now let’s connect. In the command below we put our connection info into a variable. This results in less typing later.

 C:\> $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

Finally, let’s use that variable to connect to Exchange Online and import all Exchange cmdlets into our session.

 C:\> Import-PSSession $Session

To disable clutter for your whole tenancy run the following command;

Get-Mailbox -ResultSize Unlimited | Set-Clutter -Enable $false

Until next time
