Configure archiving options to handle failures in Skype for Business Server 2015

Summary: Learn how to block IM and conferencing sessions in the case of a Skype for Business Server 2015 failure that would prevent archiving.

If archiving is a requirement for your organization, you can block IM and conferencing sessions in the event of a Skype for Business Server failure that would prevent archiving. This is sometimes called critical mode. For example, if there is a problem with a storage service, IM would be blocked for users whose communications are enabled for archiving. Both IM and conferencing automatically recover after the failures are corrected.

Configure critical mode by using the Control Panel

To specify whether communication sessions should be allowed in case of a failure that would prevent archiving:

  1. From a user account that is assigned to the CsArchivingAdministrator or CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Skype for Business Server Control Panel.

  3. In the left navigation bar, click Monitoring and Archiving, and then click Archiving Configuration.

  4. Click the name of the appropriate global, site, or pool configuration in the list of archiving configurations, click Edit, and then click Show details.

  5. To set how archiving behaves when a failure occurs, select or clear the Block instant messaging (IM) or web conferencing sessions if archiving fails check box.

  6. Click Commit.

Configure critical mode by using Windows PowerShell

You can also specify whether communication sessions should be allowed in case of a failure that would prevent archiving by using the Set-CsArchivingConfiguration cmdlet with the BlockOnArchiveFailure parameter.

For example, the following command disables communications in the case of an archiving failure:

Set-CsArchivingConfiguration -Identity "site:Redmond" -BlockOnArchiveFailure $True

The next command enables communications in the case of an archiving failure:

Set-CsArchivingConfiguration -Identity "site:Redmond" -BlockOnArchiveFailure $False

For more information, see the Help topic for the Set-CsArchivingConfiguration cmdlet.
