5. Use the Signature Pane to view and select the available Client-Side signatures.
   
   NOTE: A signature set as the default signature is shown by a pencil icon. A signature set as a default reply/forward signature is shown by an arrow icon. For more information on default signatures, see How to apply a default signature.
6. Select Details to open the Details window and view a breakdown of all the signature rules that affected the application of the signatures in the test.

8. Select Close to close the Details window.

The Details tab of the Signatures Tester shows you why signatures were or were not applied and which signature rules are affecting deployment. For more information on available signature rules, see Manage Signature Rules.

Signatures in folders

If you have created folders which store your signatures, the folders are shown by a folder icon next to the folder name in the Signatures section. If you applied folder rules, all signatures in the folder are affected by these rules. If a signature does not meet any rules set for the whole folder, it will not be applied.

_{The folder icon. If you do not have any folders, only individual signatures are shown.}

Select the arrow to expand the folder. This displays the Rules and Result sections.

The Rules expandable shows all the rules that were evaluated. Each rule has a Success (green tick) or Failure (yellow cross) icon indicating whether the rule conditions were met.

The Result expandable informs you whether the signatures were successful and, if unsuccessful, the reason why they could not apply.

• Success: If all conditions for the signature are met, all rules and the folder will have a green tick icon and the result will show Signatures applied.
• Failure: If any conditions are not met, the rules and folder will have a yellow cross icon and the Result will show Signatures in this folder were not evaluated. This is then followed by the reason for the failure.

For example, the following screenshot shows two folders: one that has failed a test and one that has succeeded. The folder called AUS has a yellow cross icon, and the Rules show that there is a sender rule in place for this folder. The sender entered in the tester is not a member of a specific group, so the Result is Signatures in this folder were not evaluated due to folder conditions. This means that none of the signatures in this folder can be applied.

The folder called UK has a green tick, meaning that all the signatures in this folder met the conditions for the Rules, so the signatures can be applied.

Individual signatures

Signatures are indicated by a card icon in the Signatures section.


_{The signature icon. Each signature is also identified with its signature name.}

The Signature Tester checks the following conditions for each signature:

• Enabled for client-side/server-side
• Senders
• Exceptions
• Recipients
• Date/Time
• Advanced Rules (Server-Side only)

Select the arrow to expand each signature. This displays the Rules and Result expandables for that signature.

NOTE: For individual signatures, the Rules and Result evaluation applies only to that signature. For example, if you are testing multiple signatures, each signature will have its own Rules and Result, as the rules are assessed for every enabled signature.

The Rules expandable shows all the rules that were evaluated. Each rule has a Success (green tick) or Failure (yellow cross) icon indicating whether the rule conditions were met. Rules that you did not set are greyed out, showing that they are not applicable to this signature and are not checked by the Tester.

The Result expandable informs you whether the signatures were successful and, if unsuccessful, the reason why they could not apply.

• Success: If all conditions for the signature are met, all rules and the folder will have a green tick icon and the result will show Signature applied.
• Failure: If any conditions are not met, the rules and folder will have a yellow cross icon and the Result will show Signature not applied. This is then followed by the reason for the failure.

For example, the following screenshot shows a successful test. The Rules for this signature all have a green tick icon, meaning this signature meets all the conditions that were set in the Manage Signature rules. The Result is therefore Signature applied.

As a further example, the following screenshot shows a failed test. The signature has a yellow cross next to the signature name, and the Rules show that although the conditions are met for the first two rules, the conditions for the rule called Date/Time trigger were not. The date/time of the test does not match the date/time chosen for the rule, so the Result is Signature not applied.

Campaigns

If you have created Campaigns, they are indicated by a card icon in the Campaigns section.

_{The Campaigns section.}

The Signature Tester checks the following conditions for each Campaign:

• Enabled for client-side/server-side
• Senders
• Exceptions
• Recipients
• Date/Time
• Advanced Rules (Server-Side only)

Select the arrow to expand each Campaign. This displays the Rules and Result expandables for that Campaign. All rules and results are processed in the same way as signatures.

The following table shows the order in which rules are processed when evaluating a signature. For more information on the signature rules, see Manage Signature Rules.

Product Type	This rule checks whether Server-Side or Client-Side is configured.
Recipient is	This rule checks if the recipient is internal or external.
Sender is	This rule checks all the senders specified in the email. The list of senders can use a combination of rules, such as individual users, groups, and advanced queries.
Recipient Rules	This rule checks all the recipient rules defined. The list of recipients can use a combination of inclusion and exclusion rules. Inclusion rules are defined by 'Any recipient is'. This can be a combination of individual recipients and domain rules. During the evaluation process, if any recipient does not meet the defined rule conditions, then the signature will fail. Exclusion rules are defined by 'Except where any recipient is'. This can be a combination of individual recipients and domain rules. During the evaluation process, if any query matches the exclusion rule, then the signature will fail.
Date/Time	This rule checks the date and time rules.
Body	NOTE: This rules is only applicable for Server-Side.   This rule checks if there are any messages set to exclude or apply signatures via trigger text, using the Advanced Rules for Server-Side deployment. These rules are always evaluated last.

 

The following table lists some of the possible errors that may stop your signatures from applying:

Error	Description
Signature rules are preventing any signature being applied. Please view the Details for more information.	This typically occurs when signatures are not enabled. You cannot test a signature before enabling it.
Only a single recipient email address is permitted	Currently, you can only test Server-Side signature results with a single recipient at a time. To test for multiple recipients, you must run multiple tests. Emails are automatically split for internal and external recipients and signatures will be applied based on the recipient settings for your signatures.
Sender domain is not valid for this tenant.	This error occurs when Azure AD/Google Workspace has not been authorized. This is a requirement for running the Signatures Tester.  To resolve this: 1. Navigate to Configuration > Manage User Data 2. Check that Enable Azure AD/Google Workspace Access displays Authorized. If this is not Authorized, complete the authorize and synchronize process for Microsoft 365 or Google Workspace. 3. Make sure all new domains are synchronized with Exclaimer. To do this, run a manual data synchronization.
