Answer 1

Check, if the Exchange Backend website bindings have a certificate assigned and is valid. Usually, a self signed SSL certificate is assigned. If not, assign it properly. If there is any issue like certificate expired or something, you may create a new certificate and assign it

Answer 2

Hi @asif ahamed ,

close this I will reinstall my lapsetup

Have you already proceeded to reinstall the setup? If haven't, I'd suggest having a check via IIS manager to make sure it's point to the correct path:

If it still doesn't help, agree with you that a reinstallation might be a quicker way to sort things out considering that it's a lab environment.

And by the way, to close a question, you can click on the Gear icon for the question or answer(at the upper right corner) and choose "Close", see Closing a question.
