When a new user is created, Appian takes their email ID as the username. Should

When a new user is created, Appian takes their email ID as the username. Should the email ID be in lowercase for it to work correctly. We have a user who was deactivated (used the application before without any issues) and now we are reactivating him back. Details below:

Name: Stuart Whitby
Username in Appian: Stuart.Whitby@aberdeen-asset.com
Email on our HR database: stuart.whitby@aberdeen.com

But even though we have reactivated the user in appian designer, the user is not able to login into the application.
Could you help?
