Short answer:
To deploy the Xink Outlook Add-in across multiple accounts in the same Microsoft 365 tenant, you must generate a unique token for each account, modify the manifest XML file with that token, and deploy each version to the correct users.
This article builds on the Outlook Add-in deployment guide and is intended for organizations deploying the Xink add-in across multiple domains or accounts (managed or independent) within the same Microsoft 365 tenant.

How to modify the manifest XML files
To support multiple accounts, you must generate a unique token for each account and download the corresponding manifest files.
Do not deploy the files immediately after downloading. Each XML file must be modified before deployment.
1. Rename each manifest file so they are unique, for example: XinkOutlookAddinManifest-Account1.xml, XinkOutlookAddinManifest-Account2.xml.
2. Open the manifest (XML file) in Notepad or another text editor.
3. Locate the GUID <Id> tag.
4. Replace the value in the <Id> tag with the account-specific token value.
Copy:
Paste:
Note: Download a separate XML file for each account. If you reuse the same file, you must also update the DomainToken values for each account.
5. Save the XML file and proceed with deployment.
6. During deployment, ensure you use a targeted deployment so each modified add-in is assigned only to the relevant users or account.
