I am using a Cisco 7941 and recently experienced a problem whereby I am unable to turn on/off alternate greeting.
Our Help Desk received this response from Cisco: the issue that is being seen is the exhaustion of MAPI connections for this mailbox. There is a maximum connection limit of 50 per subscriber. This limit is hit, and no further connections are allowed. Unity is not releasing the connection to Exchange, the only way to clear them is to restart the Information Store on the exchange server, or reboot the entire exchange server.
While this solution has not yet been attempted, my question is this: what is causing me to reach/exceed the 50 MAPI connections, and how can I avoid this in future?
As additional background, I work from home 3 days per week, so I use the alternate message to advise callers to call me at my home number, and I generally change the voice message remotely.
