SmartPhone ActiveSync Stuck Loading Email Messages


Android, iPhone ActiveSync Stuck at Loading Never displays Email

I used an available Blackberry 10 simulator and found that there was not a Loading messages the phone was stuck at displaying but indeed I had an empty non-functional connection to a test Exchange mailbox. 
   
I hope thjis post saves you some time and you have found this post quickly. This is rare problem and from I have researched about its cause is that it appears to be related to migrations of Exchange. In this case, I can say there was indeed a migration. The client's server was Exchange 2010. The client had two Mailbox servers and two CAS servers. Their email system was upgraded and migrated from an earlier release of Microsoft Exchange. 

Android, iPhone, all Devices not Displaying Email even After Successful Account Setup 


I believe the cause is not entirely due to a migration because I have seen many migrations and ActiveSync on the Smartphone, regardless whether it was an Android, IPhone, Tablets or iPads, did not have this issue.   I suspect the problem stemmed more from a history of BES (BlackBerry Enterprise Servers) and a long history of an internal Exchange organization that has seen its share of BES and Exchange upgrades/migrations. ALso, the setting which I will describe to you to change to correct this problem, I recall was often changed with BES implementations and is opposite the default setting.   

Android ActiveSync never displays Email
Android ActiveSync Never Displays Email Because of This Setting in Microsoft Users and Computers
 Active Directory 


The solution for me an I hope this works for you is simply open Active Directory Users and Computers. Locate the user, one user to test with for now will suffice, open the properties page and select the security tab, then click on the advanced button, then check the box for Inherit Permission. Save the new settings, reconnect the smartphone to the Exchange either by restarting the device or deleting and re-creating the Account on the Active-Sync Device

Active Directory Users and Computers >> Locate User >> Righ-click Properties >> Security Tab >> Advanced Button >> Check the box "Include Inheritable Permission from the Object's Parent" 

I hope this works for you as well as it worked for me and you have this post before loosing too much time.

Outlook Keeps Prompting for Logon Credentials Office 365

Outlook Keeps Asking for Password Credentials

When Outlook is configured for Office 365, the type of authentication is Anonymous Authentication. 



 For all of you that have been configuring Outlook know that this is not a normal option for Outlook authentication against an Exchange server.  We normally have, as shown below, many more options. 




Anonymous Authentication is not listed or available as an Option in Outlook 

The anonymous option is present in Outlook 2013 but Outlook 2010 and Outlook 2007 do not normally have this option listed. windows 7 is normally not a problem but since there are still many Windows XP installation out there that we need to still support, this can be an issue. 

Outlook Keeps Prompting for Credentials 

So the problem you may encounter with some XP desktop systems that still need to be supported is that Outlook 2007 or Outlook 2010 will not have this option by default. You may find on forums a repeated suggestion to update the operating system. This is not always a good option as it might break another application installed already or you have already updated but still do not have the Anonymous Authentication option in Outlook.  

I had a customer with XP SP3, Outlook 2007 which I upgraded to Outlook 2010 and applied SP1 but still no Anonymous Authentication in Outlook. I did not run anymore updates. Instead I found and ran the following Hotfix from Microsoft (I ran the 32bit version) : 

KB Article Number(s): 2791026 Language: All (Global) Platform: i386 Location: (hotfixv4.microsoft.com/.../462115_intl_i386_zip.exe

KB Article Number(s): 2791026 Language: All (Global) Platform: x64 Location: (hotfixv4.microsoft.com/.../462116_intl_x64_zip.exe


After running this fix, Outlook would not start until the system was rebooted. Once the system came back up, the Anonymous Authentication option was available in Outlook 2010 .

Using CentOS 6.4 x64 for VMware vCloud Director 5.5


Completed a complete installation of VMware vCloud Director 5.5 for a client. This was not a lab setup but the for a real cloud service.

CentOS 6.x for VMware vCloud Director

If your just starting out installing or planning your vCloud Director installation and are trying to decide whether to purchase a licensed Linux or use CentOS, I can certainly attest to the fact the CentOS operates just fine. The installation has been completed for several months now and vCloud Director has not had a single issue. I have installed two for fail-over. I do not have them in a load balance configuration. There are no caveats to using CentOS except of course it is free and thus has no profession or direct product support.

 CentOS Basic Installation for vCloud Director 5.5 

 My suggestion is to not use the basic installation option. Install CentOS with the server option and include both desktops in the installation. Or install them using YUM afterwards.

The one problem I found with CentOS 6.4 for VMware vCloud Director 5.5 was the NIC assignment. vCloud Director 5.5 requires two network interfaces. That is easy and simple enough to add. The problem comes in when there is a need to change addresses. Also, on one of the CentOS for vCloud Director installations , one of the NICs was replying for both ip addresses assigned to it.

Windows XP Login Screen - Fast User Switching

The image above is the nice login screen you get with windows XP Home or Windows XP Professional edition with fast user switching enabled. Fast user switching is usually enabled by default on windows XP but if it is not it can be enabled again. 
When windows XP Professional computer is a member of a domain, fast user switching is disabled. 
Fast user switching cannot be enabled when the computer is a member of the domain. Windows XP Home cannot be a member of a domain, only workgroup.

Outlook Web App didn't initialize - Exchange 2010

Outlook Web App didn't initialize.

If the problem continues, please contact your helpdesk.

Request Url: https://your-server-name.domain:443/owa/auth/error.aspx
User host address: ::1
OWA version: 14.1.355.2

As you will see from the posted images this Exchange 2010 server was no lab.The was a real situation.  It was not in a sterile lab with no real issues or customer waiting to use the money they lspend on new technology and hardware. How it got to this unknown but the resolution to this problem took a little time and is solid.
This Exchange 2010 server was purchased and setup for a migration from Exchange 2003 to Exchange 2010. It was not setup for demo or lab purposes. It was setup with intend and goal to be a real Exchange server for a migration from Exchange 2003 and getting put into production. But Outlook Web App was not working and this customer is going to need it. Hope this post helps someone out, Cheers!

The error message in OWA occured after the login. The OWA login page displayed okay but after the login, the following error occurred.



This is most like due to an improper security setting for the owaa virtual directoy. NOT the file system owa directory under the exchange program folder.

                   

The setting I have for owa to work are:

From within Exchange 2010 management Console






From within  IIS:






The above settings solved the error. This site had a valid cert. You don;t need one for this problem to be solved but be aware that in IIs you'll have to uncheck the box that says require SSL cert.
Cert erros are totally unrelated to this. This is strictly an authentication issue within Exchange 2010 OWA and IIS 7.

You can also use the following shell commands to test connectivity . 

Exchange management shell :

Create new exchange 2010 test user account . Run the folloing from the scripts\ directory in the exchnage program folders. Use the exchange command shell with elevated privlages to create the test account if you don;t have one already. .

new-TestCasConnectivityUser.ps1

then:

Test-OWAConnectivity

output display was the following: 

The test couldn't sign in to Outlook Web App due to an authentication failure.

The error above was displayed as output prior to the fixes noted earlier i nthis post.
