Export/Email issues getting Failed Validation error in Lightroom after computer tune up

Hi there,

Sorry that you're getting a failed validation error while trying to export or email images from Lightroom.

Which version of Lightroom are you using? Check that under the Help> System menu. Also, what it your computer's operating system?

Are you getting this error while exporting a specific set of images that are stored on your computer or any other storage location?

Would you mind checking the steps mentioned in this article https://helpx.adobe.com/lightroom-classic/kb/issue-validating-email-account-lightroom.html#ValidationfailedforGoogleGmailaccount and let us know if that helps?  

Thanks,

Akash
