Fix Claude Add-In Installation

Job ID: 40613141

Budget: $10 – $30 USD

Claude for Outlook refuses to install. Every time I click “Get Add-in,” the Microsoft Store tab at pages.store.office.com comes back with an HTTP 500 error and nothing proceeds. I’m running Outlook 365 on Windows and, so far, the only troubleshooting I’ve done is clearing my cache and cookies—no luck.

I need a proven workaround that ends with Claude fully installed and usable in my desktop Outlook client. Remote assistance is fine, but I also want a short set of repeatable steps or a manifest I can keep on file in case I need to reinstall later. If you’ve dealt with stubborn Store add-ins before—whether by side-loading, registry tweaks, or repairing the Office install—this should be quick.

Deliverables
• Claude add-in operational inside my Outlook 365
• Written procedure (or packaged files) so I can redo the install myself if needed
• Confirmation the fix survives an Outlook restart and a system reboot

Please let me know your estimated turnaround and any prerequisites you’ll need from my side.
