Workaround 1Use the EnableRoamingFolderHomepages registry value to re-enable the Enterprise Vault Search button. This Microsoft KB article describes the usage of this registry value setting as it applies to this issue. This value type should be DWORD and set with a value of 1. Note that some of the registry path keys may will need to be created if they do not already exist.
The Registry location for these settings varies by the version of Outlook. For convenience, Veritas has made available a downloadable zip file containing Registry Entries (.reg) files to create the required settings on each supported version of Outlook.
To create the Registry settings on an affected machine:
- Download the zip file attached to this article and extract it.
- Browse to the folder for the appropriate version of Outlook.
- On the affected workstation, import the contents of the .reg file by double-clicking it or by using File > Import from the Regedit application.
- Restart Outlook on the affected workstation.
The Registry settings can also be applied to a large number of machines using Group Policy.
Workaround 2Users can access their archived items via Enterprise Vault Search in a supported web browser
Workaround 3Remove the security patch
Go to Enterprise Vault Admin Console, go to the Exchange Desktop Policy properties, Advanced tab, change the drop down box called List settings from: to Outlook, and then scroll down to Search behavior and change value to "Separate browser". Then synchronized across all mailboxes for the change to take affect.
If this issue is encountered with MS Outlook 2019, use the patch for MS Outlook 2016.
SolutionThis issue has been addressed in the following releases:
Enterprise Vault 12.2.2
Enterprise Vault 12.3
NOTE: After installing the Enterprise Vault 12.2.2 or above Outlook Addin Client, Outlook must be started for the changes to be applied and then restarted for the changes to take affect.
