All,
Below is a post by a Senior Engineer at my company for a problem that began last Saturday. Our exchange transaction logs are growing wildly because of two voicemails that where intially sent to a user who's mailbox was "over the limit." No one (including Cisco and Microsoft Engineer that we have talked to so far) has been able to solve the problem. Please take a look a give me any feedback.
Thanks,

How To: Kill a voicemail that is looping

Unity_[server-name] account shows 53GB of items deleted in 7 days.
A user was over his size limit and the message could not be delivered. We fixed the users limits and made arrangements to reclaim the space from our exchange servers Unity Information Store.
Now that the message can be delivered, we see it is not the case, it is still looping. To be a bit more technical, our transaction logs and message tracking center shows that message is still replaying back and forth in a cycle from Unity_(server-name) to unity.messaging@sitename.com. I added the Unity_(Server-name) to my mailbox so I could see what is happening, and shows the VM going into the drafts from the inbox and back out over and over; up to 95,000 times a day.
Any help would be appreciated.

I have seen a case similar to this before. In that case we were able to send new messages (email and voice) to all mailboxes. However, forwarded messages with a voicemail attachment were not getting through. This failure occurred whether the message was forwarded by Unity (as it does with NDRs from outside callers) or forwarded manually using a client like Outlook Express. Unfortunately, we never found the root cause of this delivery failure. A number of changes were made in the Exchange environment (including a migration off of Ex5.5).
It looks like you may be hitting a similar issue. the "FW: Message from 8007780532" indicates that the failing message is probably an NDR being forwarded from the Unity_(server) mailbox. While I can't help with the root cause, I can maybe offer a workaround that ought to stop the looping.
By adding the following DWORD reg key and setting it to 1, you will stop Unity from automatically forwarding NDR messages from the Unity_(server) mailbox. You’ll need to restart Unity for the change to set in. The downside is now NDR messages from outside callers will collect in the Unity_(server) mailbox. You MUST monitor this mailbox and manually keep it clean. If that mailbox fills up then nobody will get their voicemail.
HKLM\SOFTWARE\Active Voice\Notifier\DisableSystemMailboxCleanout
While the root cause probably lies out in Exchange land, Unity really should be a bit more considerate and not keep trying to hammer out the same message to the point that it might bring down your message store. I’ll look into getting this enhanced by submitting a bug.
Regards,
Eric

Eric,
FYI... (May make a difference between the reg parameters)
We are running Unity 4.0(3) sr1 with no ES patches.
I looked in the registry and did not see DisableSystemMailboxCleanout under Notifier.
One thing to add is that we changed HKLM\SOFTWARE\Active Voice\ Conversations\1.0\
DWORD: Exclude Return Receipts
from 0 (false) to 1 (true).
After the reboot we still had this endless message flow still. We believe that may keep similar issues from happening in the future, but as of now the existing messages are stuck in this never ending cycle.
Blurb from UnityAdvancedSettingsTool
- This change does not affect whether Cisco Unity includes receipts when subscribers check messages by using the Cisco Unity Inbox. To exclude receipts from the Cisco Unity Inbox, use the "Unity Inbox - Exclude Return Receipts From Inbox" setting.

The registry key I mentioned above is not present by default. It would need to be created.
I beleive the "Exclude Return Receipts" setting only controls whether or not NDRs in a subscriber mailbox are present when checking messages via the TUI. It does not impact delivery of NDRs.
Below is a post by a Senior Engineer at my company for a problem that began last Saturday. Our exchange transaction logs are growing wildly because of two voicemails that where intially sent to a user who's mailbox was "over the limit." No one (including Cisco and Microsoft Engineer that we have talked to so far) has been able to solve the problem. Please take a look a give me any feedback.

I have seen a case similar to this before. In that case we were able to send new messages (email and voice) to all mailboxes. However, forwarded messages with a voicemail attachment were not getting through. This failure occurred whether the message was forwarded by Unity (as it does with NDRs from outside callers) or forwarded manually using a client like Outlook Express. Unfortunately, we never found the root cause of this delivery failure. A number of changes were made in the Exchange environment (including a migration off of Ex5.5).
It looks like you may be hitting a similar issue. the "FW: Message from 8007780532" indicates that the failing message is probably an NDR being forwarded from the Unity_(server) mailbox. While I can't help with the root cause, I can maybe offer a workaround that ought to stop the looping.
By adding the following DWORD reg key and setting it to 1, you will stop Unity from automatically forwarding NDR messages from the Unity_(server) mailbox. You’ll need to restart Unity for the change to set in. The downside is now NDR messages from outside callers will collect in the Unity_(server) mailbox. You MUST monitor this mailbox and manually keep it clean. If that mailbox fills up then nobody will get their voicemail.
HKLM\SOFTWARE\Active Voice\Notifier\DisableSystemMailboxCleanout
While the root cause probably lies out in Exchange land, Unity really should be a bit more considerate and not keep trying to hammer out the same message to the point that it might bring down your message store. I’ll look into getting this enhanced by submitting a bug.
Regards,
Eric

Eric,
FYI... (May make a difference between the reg parameters)
We are running Unity 4.0(3) sr1 with no ES patches.
I looked in the registry and did not see DisableSystemMailboxCleanout under Notifier.
One thing to add is that we changed HKLM\SOFTWARE\Active Voice\ Conversations\1.0\
DWORD: Exclude Return Receipts
from 0 (false) to 1 (true).
After the reboot we still had this endless message flow still. We believe that may keep similar issues from happening in the future, but as of now the existing messages are stuck in this never ending cycle.
Blurb from UnityAdvancedSettingsTool
- This change does not affect whether Cisco Unity includes receipts when subscribers check messages by using the Cisco Unity Inbox. To exclude receipts from the Cisco Unity Inbox, use the "Unity Inbox - Exclude Return Receipts From Inbox" setting.

The registry key I mentioned above is not present by default. It would need to be created.
I beleive the "Exclude Return Receipts" setting only controls whether or not NDRs in a subscriber mailbox are present when checking messages via the TUI. It does not impact delivery of NDRs.
