Account caching stored on different location
How does AccountCacheLocation work
This setting changes the location where the plugin stores cached files. These cached files are stored in the user roaming profile %AppData%\Zivver\OfficePlugin\accounts\[user_id]\cache by default.
Requirements
- The location is within the user’s home folder or is in a folder that the user has (writing) rights to.
- The folder is automatically emptied after ending the user session.
- The folder is on a physical device that reads and writes reasonably fast. Preferably it has the same physical drive as the installation of Outlook itself.
(1) Flash-based storage, like SSD, NVMe or PCI-E storage devices.
When to use AccountCacheLocation
Turn this setting on during troubleshooting of performance issues.
How to enable AccountCacheLocation
In the table below %Temp% is used as an example location on the drive.
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | REG_SZ | AccountCacheLocation | %Temp% |
How to disable AccountCacheLocation
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | REG_SZ | AccountCacheLocation | %AppData%\Roaming\Zivver\OfficePlugin\email_data |
Automatic File Decryption
How does EnableAutomaticFileDecryption work
This setting enables the automatic decryption of files that are received via Zivver.
When to use EnableAutomaticFileDecryption
When your organization has the policy to store unencrypted copies of Zivver messages and their attachments, for example for archiving purposes.
This setting can be disabled to improve performance.
How to enable EnableAutomaticFileDecryption
The setting is enabled by default.
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | EnableAutomaticFileDecryption | 1 |
How to disable EnableAutomaticFileDecryption
Use the registry key below to disable automatic file decryption.
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | EnableAutomaticFileDecryption | 0 |
Automatic login via SSO
Read all about the “Automatic login via SSO” registry key
Extend active session duration
Available from Office plugin version 5.4.10 and higher.
How does ShortRefreshTokenSSOTTLHours work
This setting extends the duration an user stays logged in to the Office plugin. By default the session duration is 12 hours. This means users have to log in to Zivver every 12 hours, which in practice means every day.
When to use ShortRefreshTokenSSOTTLHours
When your organization uses the Office Plugin in controlled working environments such as Citrix or Remote Desktops it makes sense to extend the duration. This will improve the user experience because users are logged in for a longer period of time in Zivver.
Zivver does not recommend to use this setting on personal or public devices.
How to enable ShortRefreshTokenSSOTTLHours
The example below sets the value for the ShortRefreshTokenSSOTTLHours to 720 (in hours), which is roughly equal to a token that expires every month. You can change the value to any value that you like as long as this potential security risks for extended token duration is considered.
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | ShortRefreshTokenSSOTTLHours | 720 (decimals) |
How to disable ShortRefreshTokenSSOTTLHours
This setting is always enabled, however you can revert back to default by using 12 as value.
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | ShortRefreshTokenSSOTTLHours | 12 (decimals) |
Do not show user tutorials
How does DoNotShowTutorials work
This setting determines if users see a tutorial when the user is first logged in to the Zivver Office Plugin. The tutorial shows the main points in the Office Plugin and can be skipped by the user.
When to use DoNotShowTutorials
When your organization is implementing Zivver and users are being exposed to the Office Plugin for the first time. If your organization provides user training for the Office Plugin for each user, then this setting may be disabled.
How to enable DoNotShowTutorials
When enabled the user will not see any Zivver tutorials.
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | DoNotShowTutorials | 1 |

Read all about the “HighlyConfidentialDomains” registry key
Block users from sending with Zivver
Available from Office Plugin version 5.4.10 and higher
How does HighlyConfidentialDomainsBlocksZivverSending work
This setting blocks users from sending a Zivver message when a domain is on the HighlyConfidentialDomains list. It is required to have the HighlyConfidentialDomains list enabled before enabling this setting.
When to use HighlyConfidentialDomainsBlocksZivverSending

When to use EnableZivverAttachmentsWithMailAssistedSubmission
You can enable this setting if your organization does not want to send emails with large attachments. The maximum attachment size depends on the maximum message size configured in your mail server.
You can disable this setting if your organization requires all attachments to pass through your mail server, for example for document management software.
How to enable EnableZivverAttachmentsWithMailAssistedSubmission
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | EnableZivverAttachmentsWithMailAssistedSubmission | 1 |

| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | DWORD | EnableZivverAttachmentsWithMailAssistedSubmission | 0 |
Use email verification by default
How does UseEmailVerificationAsDefault work
This setting automatically applies “Email verification” instead of prompting the user to set a verification method for added security. This setting decreases the average security of all sent Zivver messages. If a verification method is already available in Zivver for the recipient, then that verification method will be used over Email verification.
This setting is enabled by default for version 5.4.12 and higher.

Set maximum attachment size for unencrypted messages
How does MaxSizeForAttachmentsToAttachToMail work
Email attachments are saved with the email when Zivver messages are stored locally unencrypted. Attachments larger than 5 megabyte(MB) will referenced to by a download link to the Zivver portal. Reasoning for this feature is that attachments of Zivver messages can be much larger than the standard 20MB attachment size of Microsoft Exchange server.
With this setting, you can set the maximum email size that is saved unencrypted so that it matches your Exchange maximum email size.
When to MaxSizeForAttachmentsToAttachToMail
Use this setting when you need to save emails that are larger than 20MB together with the attachments.
How to enable MaxSizeForAttachmentsToAttachToMail
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | REG_DWORD | MaxSizeForAttachmentsToAttachToMail | 50 |
The above example makes emails possible with attachments up to 50MB in size. The value needs to be a decimal and can be smaller or larger than the example above. The value should not exceed the Exchange attachment size limit.
How to disable MaxSizeForAttachmentsToAttachToMail
| Key | Type | Name | Value |
|---|---|---|---|
| HKEY_CURRENT_USER\SOFTWARE\Zivver\OfficePlugin\Settings | REG_DWORD | MaxSizeForAttachmentsToAttachToMail | 20 |
