Question

Hi, I receive payment receipts via a link in an email, and they have always worked fine.

However the latest email link does not work. I have checked previous emails and they have stopped working too. Is this something the vendor needs to fix, or is it my Outlook configuration?

I am using Microsoft® Outlook® 2019 MSO (Version 2407 Build 16.0.17830.20056) 32-bit

This is the full error;

Hi @Shane Arnold

Welcome to our forum!

Does the error occur recently on Outlook Desktop Client? Do you have any specific operation before the error occurred? 

To further confirm if the error is more related to Outlook desktop client, if possible, please log in to your web mail and do the same test to check if the error persists. 

If the error does not persist, please take the following steps:

1. Update Outlook: Ensure that you are using the latest version of Outlook. Sometimes, updating the software can resolve unexpected issues.
2. Repair your Outlook profile:
   • Open Outlook and go to File > Account Settings > Account Settings.
   • Select your email account and click Repair.
   • Follow the prompts to complete the repair process.
3. Create a new profile: If all above do not work, considering data file corruption, it is proposed that you create a new profile, re-add your account to the new profile and check if the same error still occurs. 

If the error persists, since the error message indicates an issue with the server's authentication, it is recommended that please contact the link vendor and inform them about the problem. They might need to check their server configuration and ensure that the links are generated correctly.

Hope it helps!
