I administrator my company's inherited Unity voice mail system. It was originally setup in 1999(!) and runs on NT 4 with IIS and Exchange 5.5. It has been working fine for the last two years I've administered it but today a big problem started. Recently it refused to create new voice mail accounts stating that there were no more licenses. Another employee told me that was because Unity does not delete old accounts on the Exchange side. So lo and behold there were a couple of hundred accounts of people I've never seen before! I carefully deleted accounts in the Exchange administration tool and ever since then Unity has refused to start. It will try to start itself when manually told to but gives up within 15 seconds. I made very sure that I did not delete any known admin accounts. I don't have the error log in front of me right now but every hour or so there will be 4 alerts stating that the Exchange IMAP service could not be started or logged into. The first log of the problem stated something like AvComponent Manager has an error. I've googled for a solution to this of course but nine year old systems are pretty scarce! I have telco support and will be able to rely on them for some support but if the community here has any leads or ideas on how to help with this it would be _greatly_ appreciated.
