<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>We ran into an issue with messages not being delivered after
applying some Exchange hotfixes (KB912442, KB916803) - it only affected certain
subscribers and those users did have AD accounts that belonged to administrative
groups. The errors we were seeing in the AvCsMgr logs indicated that it
was a permissions issue:<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>We re-ran the Permissions Wizard, which was a newer version
(not older than 2.1.0.25 as mentioned in this TechNote <a
href="http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_tech_note09186a00806c3575.shtml">http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_tech_note09186a00806c3575.shtml</a>)
but it didn’t seem to fix anything. Our Exchange admin did temporarily
remove KB912442 which seemed to resolve the issue, but we had been planning to
upgrade to Unity 4.2 anyways, so we went ahead with that; he re-applied the
patch, we re-ran the 4.2(1) Permissions Wizard, and everything has been OK
since then. There was some discussion on the voice forums indicating that
you didn’t have to remove the patch, just set the necessary permissions
for the message store account; we didn’t try that, but it sounds like it
could be a solution. <a
