XPERIA X1 Sony Ericsson messaging

I worked at Client who wanted to use her Cell phone to send/receive her corporate e-mails using XPERIA X1 Sony Ericsson.

I enjoyed a hassle free setup. I started off by preparing the client’s Microsoft Exchange server and ISA Server Firewalling to make sure that all bits and pieces are configured properly. I am not going to cover the configuration details of Exchange and ISA on this article.

Then I moved on to XPERIA X1 Sony Ericsson device. Honestly, the configuration was similar to setting up any outlook profile. You can also use outlook web access which works perfectly fine on this device.

XPERIA X1 Sony Ericsson is perfect for  “users on the go” who require full access to their company messaging Environment.

BrightStor ARCserve Backup — Backup

W3401
Unable to find file. (FILE=C:\es-ca-01_w3svc1_cert.pfx, EC=The system cannot find the file specified.)

Technical:  Session Status…………… Incomplete

The above mentioned error happened because the file was deleted.

Resolution:

Since the backup cannot find the file specified – what needs to happen is to modify backup to exclude the above file.

RPC over http/s problem. Outlook status remains disconnected.

You’ve deployed RPC over HTTP/s as per “How can I configure RPC over HTTP/S on Exchange 2003 (single server scenario)? ” document and when you test the functionality of both OWA and RPC using internet Explorer (https://webmail.yourdomain.co.za/exchange) and (https://webmail.yourdomain.co.za/rpc/rpcproxy.dll) it works. However, when you test the RPC connectivity on outlook 2003/2007 the status remains disconnected.

Resolution:

Open up outlook – Tools – Accounting Settings – Change – More Settings – Connection

Select Basic Authentication – Under Proxy Authentication Settings

If the above doesn’t fix your problem try the following:
Click start – Run – cmd – type nslookup – then enter
type – webmail.yourdomain.co.za
This should reveal the external IP address(xxx.xxx.xxx.xx). Copy or right down this info about external IP Address.
Now go and Right Click on start – go to Explore – C:\WINDOWS\system32\drivers\etc – open hosts and enter your external IP address for webmail.yourdomain.co.za.
(e.g)
xxx.xxx.xxx.xx   webmail.yourdomain.co.za
Save the changes, Close your hosts and restart your PC. After a reboot all should work.

Setup Failed while creating ISA Server storage

Migrating from ISA 2004 Standard Edition to ISA 2006 Standard Edition and the installation comes up with the following error message “Setup Failed while creating ISA server storage”. The ISA 2006 installation rolls back, interestingly it wipes ISA 2004 off of the server.

NB: Hoping that you took ISA 2004 backup before running ISA Server 2006 setup. 

Resolution: 
 
To work around this problem, follow these steps.

Right Click My Computer – Properties – go to Computer Name – Rejoin your ISA Server to the Domain – allow your Server to restart. After a reboot – my ISA 2006 Server Installation completed successful. All I did was to import data from an exported XML (ISA 2004 backup) configuration file into a newly installed ISA 2006 Server.
