Hi, pls i am having a problem signing on the office communicator 2007 i am running in the lab. Its the trial version. I can connect to the ocs2007 server using web access but i dont understand why i cant connect with the communicator client. The error says
"there was a problem verifying the certificate from the server. Please contact your system administrator" when i use the manual configuration with TLS method. If i change the setting to automatic configuration, it gives the error "cannot sign in because the server is temporarily unavailable...". Could you tell me what to do to resolve this? thanks.

Hi Marc

I've just installed OCS 2007 R2 on a lab server and Office Communicator 2007 R2 on a PC. Everything works fine!

Now I want to use Office Communicator Mobile R2
on my HTC TyTNII WIndows Mobile 6.0 device

I download CommunicatorMobile.SP.msi
from Microsoft web site.

I try to install using Windows Mobile Device Center.

It says the application is not compatible with my device!

So I upgrade my device to Windows Mobile 6.1

That was painful, since the whole device configuration
is lost during the upgrade.

Windows Mobile Device Center again says the application
is not compatible!

I copy the CAB file to my device and double click it.

Then I see an error message (in Spanish)
Error installing Communicator.SP.cab
The installer file is not compatible with this device
(the error message is in spanish, this is a more or less
accurate translation)

So Microsoft has posted an installer that is not
compatible with Windows Mobile 6.0 and 6.1?

Please help!

You have the incorrect download. You need CommunicatorMobile.PPC.msi.

Hello my name is Eduard and work in the implementation of OCS
in a financial institution here in Spain, look at you because consulto
I interpret that is advanced in this regard. My question was
whether there is the possibility to disconnect a session from OCS
if the user starts on another computer, just as it does
the messenger. Ie they can only see an active session
user. There is that possibility.

Thank you very much to the hand and congratulate you on your blog.

Best regards

How do yu move the location of the Conversation history folder? I need to move it out of my mailbox and into a pst folder... It's HUGE! Why are these files so large?

I looked at a short conversation of my own, and it's full of verbose XML. Here's a sample (sanitized to remove identity info):
<participantPropertyChange xmlns="http://schemas.microsoft.com/2008/10/sip/convItems" xmlns:ct="http://schemas.microsoft.com/2006/09/sip/commontypes" ts="2010-02-01T11:02:36Z" propName="supportAudioRender" isLocal="true" participantUri="sip:xxxxxx.x.xxxxxxx@xxxxxxxxxxxxxx.com">
<oldValue>
<emptyValue>0</emptyValue>
</oldValue>
<newValue>
<boolValue>true</boolValue>
</newValue>
</participantPropertyChange>

There are thousands of lines of this stuff. In the conversation I sampled, there are 7400 lines of this sort of thing, amounting to 460 Kb. If I save the conversation as text only, it's less than 8 Kb!
