A family of Microsoft word processing software products for creating web, email, and print documents.
Dear Wordster888,
Please check whether the Use Ctrl+Click to follow hyperlink is ticked in the user's Word application.
If no, the issue may happen and I suggest you untick it and then download the file from the email to see whether the issue disappears.
If the recipient is from another company or tenant, I'd like you to let him check whether the GPO policy is enabled on Use Ctrl+Click to follow hyperlink in his environment.
If yes, that may be the root cause of the issue and he may need to disable the policy to move forward.
Do the recipient use the same version of the Word application as you? If it is convenient, upload a full screenshot of the Account page in the Word application for our reference. You can access the page via clicking on File>Account.
Note: Remove any private information before uploading the screenshots.
Welcome to share any updates at your convenience.
Thank you for your effort and time.
Sincerely
Cliff | Microsoft Community Moderator
