Why Disabling Single Inbox Is Important Before Restoring Exchange Mailboxes for Cisco Unity Connection 8.5 and Later

If you want to restore Exchange mailboxes and the single-inbox unified messaging service capability is enabled for Cisco Unity Connection users whose Exchange mailboxes are being restored, you must disable single inbox for those users before you restore Exchange.

For information on how disabling single inbox affects synchronization behavior, see the "How Disabling and Re-enabling Single Inbox Affects the Synchronization of Connection and Exchange Mailboxes" section.


Caution If you do not disable single inbox for Connection users whose Exchange mailboxes are being restored, Connection will not resynchronize voice messages that were received between the time that the backup from which you are restoring was created and the time that the restore is complete.

Connection maintains a synchronization cache that tracks which voice messages have already been forwarded to Exchange. When you disable single inbox, the synchronization cache is automatically cleared. Here is how it works:

1. You back up Exchange.

2. A new voice message arrives.

3. Connection synchronizes the voice message with the Exchange mailbox associated with the Connection user.

4. Connection updates the synchronization cache for that user to indicate that the message has been synchronized with Exchange.

5. A hard disk in the Exchange server fails.

6. You disable single inbox for the Connection user whose Exchange mailbox was on the failed hard disk.

7. Connection clears the synchronization cache for that user.

8. You replace the hard disk and restore Exchange from the backup that you made in 1.

9. You re-enable single inbox for the user.

10. Connection performs a periodic comparison of the synchronization cache with the voice messages currently in Exchange.

11. Because the cache is empty, Connection concludes that voice messages that are in the Connection mailbox but not in the Exchange mailbox have not yet been synchronized with Exchange.

12. Connection resynchronizes the Connection mailbox with the Exchange mailbox, and rebuilds the synchronization cache.

If you restore Exchange mailboxes without disabling single inbox for the Connection users, here is an explanation of why Connection deletes all voice messages that were received after the backup from which you are restoring:

1. You back up Exchange.

2. A new voice message arrives.

3. Connection synchronizes the voice message with the Exchange mailbox associated with the Connection user.

4. Connection updates the synchronization cache for that user to indicate that the message has been synchronized with Exchange.

5. A hard disk in the Exchange server fails.

6. You replace the hard disk and restore Exchange from the backup that you made in 1.

7. Connection performs a periodic comparison of the synchronization cache with the voice messages currently in Exchange. The voice message that arrived in 2. is not in the Exchange mailbox for the associated Connection user.

8. Connection concludes that the voice message has already been synchronized with Exchange and does not resynchronize the message into the Exchange mailbox.

Task List for Restoring Microsoft Exchange Mailboxes in Cisco Unity Connection 8.5 and Later When Single Inbox Is Enabled

1. Disable single inbox for selected users or for a unified messaging service. See the "Disabling Single Inbox for Cisco Unity Connection 8.5 and Later" section.

2. Restore Exchange mailboxes. For more information, see the applicable Microsoft documentation.

3. Re-enable single inbox by reversing the procedure that you used to disable single inbox in Task 1.:

If you disabled single inbox for individual users by using Connection Administration, repeat the "To Disable Single Inbox for Individual Users for Connection 8.5 and Later" procedure, but check the Synchronize Connection and Exchange Mailboxes (Single Inbox) check box.

If you disabled single inbox for a unified messaging service, repeat the "To Disable Single Inbox for All of the Users Associated with a Unified Messaging Service for Connection 8.5 and Later" procedure, but check either the Synchronize Connection and Exchange Mailboxes (Single Inbox) check box or the Enabled check box, as applicable.

If you disabled single inbox for individual users by using the Bulk Administration Tool, repeat the "To Disable Single Inbox for a Large Numbers of Selected Users by Using the Bulk Administration Tool for Connection 8.5 and Later" procedure, but change the value of enableMbxSynch to 1.

Disabling Single Inbox for Cisco Unity Connection 8.5 and Later

The first step in restoring Exchange mailboxes is to disable single inbox, as noted in the "Why Disabling Single Inbox Is Important Before Restoring Exchange Mailboxes for Cisco Unity Connection 8.5 and Later" section. You can do so in several ways, depending on how many Exchange mailboxes you are restoring, whether you are restoring Exchange mailboxes for all of the associated with a unified messaging service, and how concerned you are about affecting Connection functionality during the restore.


Note For information on how disabling single inbox affects synchronization, see the "How Disabling and Re-enabling Single Inbox Affects the Synchronization of Connection and Exchange Mailboxes" section.


Restoring Exchange Mailboxes for a Small Number of Users

If you are restoring Exchange mailboxes for a small number of users, you can disable single inbox on individual user accounts by using Connection Administration. See the "To Disable Single Inbox for Individual Users for Connection 8.5 and Later" procedure.

Restoring Exchange Mailboxes for All of the Users Associated with a Unified Messaging Service, or Restoring Mailboxes When Connection Functionality Is Not a Concern

When you are restoring Exchange mailboxes and either of the following is true, you can disable single inbox for a unified messaging service, which disables single inbox functionality for all users associated with the unified messaging service:

You are restoring mailboxes for all of the users associated with a unified messaging service.

You are restoring mailboxes for selected users associated with a unified messaging service, and you are restoring mailboxes during non-business hours, when interrupting single inbox functionality has less impact on users.

There are two ways to disable single inbox for a unified messaging service:

Disable only single inbox for a unified messaging service: If you disable only single inbox, the Connection conversation continues to play the options for the other unified messaging features. If a user selects one of these features while Exchange is unavailable, the Connection conversation announces that access to messages is unavailable at this time.

Disable an entire unified messaging service: If the unified messaging service also has the other unified messaging features enabled and you disable the service, the Connection conversation stops playing the options for those features until the unified messaging service is re-enabled, which could be confusing for users.

See the "To Disable Single Inbox for All of the Users Associated with a Unified Messaging Service for Connection 8.5 and Later" procedure.

Restoring Exchange Mailboxes for Some but Not All Users Associated with a Unified Messaging Service When Connection Functionality Is a Concern

When you are restoring Exchange mailboxes for a large number of users who are associated with a unified messaging service and both of the following are true, you can use the Bulk Administration Tool to disable single inbox for individual users:

The unified messaging service also includes users whose mailboxes you are not restoring.

You are restoring the mailboxes during business hours, when you want to minimize the impact on users whose mailboxes you are not restoring.

See the "To Disable Single Inbox for a Large Numbers of Selected Users by Using the Bulk Administration Tool for Connection 8.5 and Later" procedure.
