How CodeTwo client-side signature adding options affect Outlook’s default signature settings

Problem:

You are using CodeTwo Email Signatures for Office 365 in client-side mode. After installing the CodeTwo Signatures Add-in for Outlook, your Outlook signatures are no longer set as the default ones for new messages or for replies/forwards and are not inserted automatically when composing an email. And even if you set your Outlook signatures as default ones, the changes you made are reverted after some time.

Solution:

Client-side signature rules created in CodeTwo Email Signatures for Office 365 control which signature is added by default in Outlook (Fig. 1.). This applies to the default signature for new messages and/or for replies and forwards. To learn more about these controls, read this article.

When a client-side signature rule is configured to add a default signature, this signature will also be set as the default one in the Signatures and Stationery window in Outlook, and will be inserted automatically into emails (Fig. 2.).

Even if none of your client-side signature rules is configured to add a default signature (as shown in Fig. 3.), the CodeTwo add-in still controls the default signature settings in Outlook.

The signature added based on this signature rule will not be set as the default one in Outlook.

In this case, the default signature for new messages and/or for replies and forwards in Outlook is set to none. This means no signature will be inserted automatically when composing an email in Outlook (Fig. 4.).

No default signature is set in Outlook.

If a user changes any of the default signature settings in the Signatures and Stationery window in Outlook, this change will remain in place until the CodeTwo Signatures Add-in for Outlook is synchronized. During the next synchronization (which occurs automatically), our add-in will display the Outlook restart required message, as shown in Fig. 5. When Outlook is restarted, the default signature settings will be overwritten and changed back to the values set in the signature management app. This will continue as long as the user is signed in to the add-in.

The CodeTwo Signatures Add-in for Outlook detected that some settings have been changed, and Outlook needs to be restarted.
