Short answer:
To use different signatures for multiple accounts in Classic Outlook, set your primary account as the default for Xink and manually assign optional signatures to secondary accounts. Use (Do not change) to prevent Xink from overwriting them.
Summary: This guide explains how to allow users to manually select and use different email signatures for secondary email accounts, while Xink continues to manage the primary account.
Step 1: Set the default account for Xink
Open Outlook and go to File > Account Settings:

Ensure your Default account is the account you want Xink to manage.

Step 2: Confirm primary account signatures (Xink managed)
The primary account (e.g. eric@xink.io) will automatically receive the default New and Reply signatures assigned in the Xink admin portal.

Step 3: Assign signatures to a secondary account
Switch to your secondary email account (e.g. xinkdemo@gmail.com) and manually assign optional signatures as Default and Reply:

Click OK to save your changes.
Step 4: Verify in Compose view
Create a new email and switch between accounts:
- The primary account will show the Xink-managed signature.
- The secondary account will show the manually assigned signature.

Important: Prevent overwriting
Before testing, ensure the signature setting is set to (Do not change) in Xink. This prevents the client from overwriting manually assigned signatures.

Step 5: Test your setup
- Open the Xink app and click Update Now.
- Return to Outlook and click New Email.
- Verify signatures for both accounts:
- The primary account shows the Xink-assigned signature.

- The secondary account shows your manually assigned signature.

Next steps
You can now allow users to personalize signatures for secondary accounts while maintaining centralized control for the primary account.
