Trying to see if anyone has seen this before. VMs were being successfully left and retrieved from a particular VM box. Yesterday over 200 VMs appeared in the mailbox with timestamps ranging from about the time an upgrade was done (October 2013 from 7.1(5) to 9.x to present day. The only thing anyone knows for sure was done was a resync of the MWI on the same day and within a couple of hours of the new VMs being seen.
Syncrhonizing MWI shouldn't lead to recovering 200 voicemail messages.
If yu are using UM/Single Inbox then I would be curious to see if someone did a restore on the Exchange side.
I am also curious on message retention policies. How is CUC configured to handle saved and deleted messages. Do you purge deleted messages?
This line of quesitioning is not related to the Exchange statement. I am just curious and pondering (in the back of my mind) if there was a way to undelete 200 messages on purpose or by way of software defect/issue. If you are purging messages then that thought is moot.
Sorry, no answers but it is an interesting problem for sure.
