Outlook 2010 not responding, hangs, freezes or stopped working when going from one email to another

Question

Hi all,
I have an issue with one of my clients running Office Pro Plus 2010 32bit on windows 7 pro with exchange 2010 service pack 3 where they have voicemails coming in as .wav files and have a rule set up to automatically going into a sub-folder call
"voicemails". I have deleted all the voicemails except for 5 for testing purposes (as there was over 800 messages and thought this could of been the culprit). When opening these voicemail emails, outlook doesn't respond for about 1-2 minutes and
then opens the email eventually, then I can open the .wav file. The .wav files are approximately 50kb to 200kb in size. All other attachments seem to open quickly with the rading pane on or off.
Troubleshooting Steps I have done;
- Install the latest updates
- Check to make sure Outlook is not in use by another process
- Investigate possible issues with add-ins
- Check to see if your mailbox is oversized
- Repair your Office programs
- Repair your Outlook Data files
- Check to see if your antivirus software is up-to-date or conflicting with Outlook
- Create a new user profile in Outlook
- Created a new .OST
- Perform a Selective Startup to determine if another program is conflicting with Outlook (for advanced user)
- Create a new Windows user profile (for advanced user)
- Started in outlook /safe mode
- Turned off chached mode
- Checked error logs and receive a Outlook Hang error ID: 10001
Since doing all the above troubleshooting, I have found out the same problems occur within a Terminal Server Session (Server 2009 R2 with Service 1) running Outlook 2010 Professional Plus.
One thing I notice is that when I click on one of the email messages, where is usually says "connected to MS exchange", it is saying "requesting data from exchange".
The above is happening with another user so this is not user specific.
If you need any other info, just let me know.
Thanks in advance.

Hi,
Logon OWA and check if the voicemails can be played fine, make sure the mails are good.
If you have installed the improper drivers for any devices or hardwares, this kind of issue may occur. Actually some devices which seem to have nothing to do with the issue may also be the culprit, like a printer or some audio devices in this case.
Try restore the system to an earlier date if you have backup.
If you have got the logs, you may post the complete logs here, it may help to determine the cause of the issue.

Thank you very much for your reply. I could access in OWA successfully with a quick response and used this as a workaround. There was not too many logs to go from.
It looks like there was a server that was decommissioned around 6 months ago and just a test thought I would start this up to see if our voicemail server had any relationship with it - once I started this server up, voicemails
were opening quickly will all users. I am not sure if our voicemail  software (Cisco Unity) is pointing to our old server or if has anything to do with DNS entries but will need to dive into this further as we cannot have the old server online for too
much longer.
If anyone would have an inclining as to what this could be, please let me know.
Thanks again.
