Hi @Shailesh Rana
Thank you for posting your question in the Q&A Forum.
We understand that you are encountering difficulties while attempting to update your Outlook 2016 client, and we would be happy to assist you.
To ensure your online safety, I have redacted your personal contact information from your original post, as this is a public forum accessible to everyone. For your protection, all support will be conducted directly through this discussion thread.
To help us tailor the right solution for you, could you please let us know a bit more about the situation:
- May I ask if you are seeing any specific error messages (e.g., 0x8007xxxx) or codes when you attempt to update?
- It would be helpful to know if your Outlook 2016 is a standalone perpetual license or part of a Microsoft 365 business subscription.
- Could you also kindly inform us which version of Windows you are currently using?
In the meantime, you may attempt to initiate a manual repair of the Office suite:
- Navigate to Control Panel > Programs and Features.
- Select Microsoft Office 2016 and click Change.
- Select Quick Repair and follow the on-screen instructions.
