Email Problem
Try connecting with Facebook. If not do you have your number connected with your email?
If your email is blocked and you can't access it you can try to call the company and follow through the steps to get your email unblock.

Oh, this is terrible, I also encountered this. This breaks everything and prevents you from working normally and receiving information. Unfortunately, I was unable to recover the data.
This is a common problem for those who actively use accounts and especially if it is somehow related to work. To do this, I always try to have a backup and store all data in convenient formats and use mbox to pst converter from https://www.outlooktransfer.com/products/mbox-to-outlook-transfer/ as this is the most convenient option. I hope you can somehow resolve this issue and recover the data.
