Hi @Bhakti , welcome to the Community!
The email address you mentioned returned an error to our mail delivery service:
550: 550 #5.1.0 Address rejected
I've cleared the error out on our end, but it's possible there might be something amiss with your company's email server. I would suggest trying to send your company email address an email from an outside account - perhaps a gmail address - and seeing if you receive it at your company email. If so, you should be clear to resend the invitation email from Bitbucket and have it properly delivered this time around.
