I am running Desktop Client 2.50.06.27 with a Call Pilot 100 on a CICS.
Seems to cause hanging problems when tested with the Beta of Outlook
2007.First message comes in just fine but no others - deleting a message from the desktop works fine, but then no further features of Nortel desktop messaging seem to work.
I guess Nortel will say it's not certified for Office 2007 yet. I guess it will take them forever as it did to run their software on Windows XP.
I think I have the latest release of the desktop clients......
