When I first started using Outlook for Android it was running great. I use it to check three different email accounts–two accounts in Office 365 and one Outlook.com.
However, as the months went by the app seemed to get slower and slower, with more frequent blank screens. These blank screens would appear most often when I would try to pull up my folder list (pictured below)
Although it would happen at other times as well. Such as trying to open an email (pictured below).
This delay would generally last a few seconds. But sometimes it could take as long as 10 seconds for the folder list or email to appear. Certainly enough to hinder productivity in the app. [Read more…] about Fixing frequent blank screens in Outlook for iOS & Android
After installing the Windows 10 Fall Creators Update (Build 1709) on my PC, all my network connections–whether wired or wireless–were broken. When I checked device manager I had a exclamation mark against all but one network device. The only device excluded from error was the “Check Point Virtual Network Adapter”.
Going into the properties of one of these devices gave equally cryptic errors. All devices reported the same thing.
Windows is still setting up the class configuration for this device. (Code 56)
A couple extra reboots did not resolve the odd error either.
A quick search on the internet revealed forum postings that identified the Check Point VPN as the culprit (credit SOHIC for the answer). This made sense as the version of the Check Point software I had made no mention that it was supported on Windows 10. My bad!
But this was the key. When I uninstalled the software, and rebooted, all my network connections came back to life. [Read more…] about All network connections broken – Windows 10 Fall Creators Update
Ran into an issue recently where Outlook was working fine, however Android devices, particularly mobile phones, would throw an error that the certificate was invalid when configuring an Exchange mailbox via the GMail app. The error was:
Certificate not valid The Gmail app can't guarantee the security of this email address. Your messages would be at risk.
When clicking Advanced we received more clarification that the certificate was not trusted. However, we could quickly see that the correct certificate was being presented to the Android devices and it clearly wasn’t an issue with the date.
Certificate not trusted Contact your email provider about this error, or proceed with username (unsafe).
We then tested our certificate with DigiCert’s SSL Certificate Checker. This is a great tool to confirm that the certificate is installed correctly and that the certificate path is valid. You can check any certificate with this tool. It does not have to be a certificate issued by DigiCert. In our case we were testing our GoDaddy certificate with this tool.

While reviewing the event logs on your Exchange server you could encounter the following error.
Log Name: Application Source: MSExchange ADAccess Event ID: 2112 Task Category: Topology Description: Process Microsoft.Exchange.Directory.TopologyService.exe (PID=2700). The Exchange computer dc03.supertekboy.com does not have Audit Security Privilege on the domain controller dc03.supertekboy.com. This domain controller will not be used by Exchange Active Directory Provider.
We ran into this recently at a customer. This was an odd error because the description specified the name of one of our domain controllers as an “Exchange Computer”. That aside, my customer was receiving this error for two of their three domain controllers (dc02 & dc03). The error was also repeated across all their Exchange servers.
To make matters worse if the customer shut down the only domain controller not reported in these errors (dc01) Exchange would become completely unavailable. As the error stated, dc02 and dc03 were definitely not being used by the Exchange Active Directory Provider.
Further analysis of the event logs also revealed informational alert MSExchange ADAccess 2080. In this alert we could see our three domain controllers with one striking difference.
Log Name: Application Source: MSExchange ADAccess Event ID: 2080 Task Category: Topology Description: Exchange Active Directory Provider has discovered the following servers with the following characteristics: (Server name | Roles | Enabled | Reachability | Synchronized | GC capable | PDC | SACL right | Critical Data | Netlogon | OS Version) In-site: dc01.supertekboy.com CDG 1 7 7 1 0 1 1 7 1 dc02.supertekboy.com CDG 1 7 7 1 0 0 1 7 1 dc03.supertekboy.com CDG 1 7 7 1 0 0 1 7 1
In the eighth column (highlighted), dc01 was reporting a 1 whereas dc02 and dc03 were reporting a 0. All other column data was identical between the three servers. The words in parenthesis are actually the column headers. They don’t line up very well in event viewer but if we count to the eighth word we see the column is titled “SACL right”. What this means is that the Exchange servers are missing the SACL right on the domain controllers marked with a zero. Or more specifically, Exchange is missing the right to manage the security and audit logs of those two domain controllers.

In this article we are going to take a look at changing which objects get synced to Office 365 through organizational unit (OU) filtering. By default Azure AD Connect is configured to sync all objects in all OUs. Filtering allows us exclude OUs, and the objects they contain, so they are not synchronized to Office 365. An example of this may be to exclude an OU that contains service accounts for on-premises applications.
In our example, we are going to narrow our sync scope to just a few select organizational units in the domain skaro.local. We will be working with the latest version of Azure AD Connect and a single forest environment.
Let’s get started!
Selecting which OUs to synchronize
First, log onto the server where you have Azure AD Connect installed and open the Synchronization Service program.
This opens the Synchronization Service Manager. From here select the Connectors tab. Under the Connectors section double-click the name of your local Active Directory. In my example, this is SKARO.LOCAL. This will bring up the Properties screen for that connector.
When installing an Exchange update you may run into the following error.
Error: The following error was generated when "$error.Clear(); & $RoleBinPath\ServiceControl.ps1 -Operation:DisableServices -Roles:($RoleRoles.Replace('Role','').Split(',')) -SetupScriptsDirectory:$RoleBinPath; & $RoleBinPath\ServiceControl.ps1 Stop $RoleRoles.Replace('Role','').Split(',') " was run: "Microsoft.Exchange.Configuration.Tasks.ServiceStopFailureException: Service 'tmlisten' failed to stop due to error:'Cannot stop tmlisten service on computer ---> System.InvalidOperationException: Cannot stop tmlisten service on computer ---> System.ComponentModel.Win32Exception: The requested control is not valid for this service
The tmlisten service is associated with the Trend Micro antivirus product and specifically the Trend Micro Listener service. This service requires a password to stop and can not be disabled via either the services snap-in or command line.[Read more…] about Error ‘Cannot stop tmlisten service’ when installing Exchange updates
While attempting to configure an Outlook client with an Exchange mailbox I ran into an issue where the account creation would not complete. Instead, Outlook would stop on “Search for server settings” and prompt me for a username and password. The credentials of my Exchange account did not work and kicked back the login prompt.
When I attempted to test Autodiscover using testconnectivity.microsoft.com I ran into an even stranger error. Autodiscover appeared to work. But I received the error “No account settings were returned from the Autodiscover response”.
Examining the Autodiscover response I noticed that the test was successfully completing against the root of supertekboy.com. This was odd as supertekboy.com is redirected to the website www.supertekboy.com where no Autodiscover responses should be happening.
However, when attempting to plug the Autodiscover URL into a web browser I found that something was responding to Autodiscover requests. It was responding with an error of “Autodiscovery must be provided a valid email address”.
This isn’t an Exchange or Office 365 autodiscover response. Instead this was my web hosting provider responding to my Autodiscover request. Specifically, cPanel. cPanel has its own implementation of autodiscover, which allows Outlook and other email clients to automatically configure themselves for a cPanel mailbox. Unfortunately, this conflicts with autodiscover locating an Exchange or Office 365 mailbox. [Read more…] about No account settings were returned from the Autodiscover response
