I pay $83.00 annually for more than 7 years to Microsoft for use of Office 365. In turn, Microsoft provides Office 365, and Outlook Mail. I have had the email address in Outlook mail of kristen.[protected]@live.com for more than 15 years. Every business contact I have made as a freelance copywriter and Ecommerce developer is in this account. I cannot work without access to this email account. On March 3/26/21, I logged into my Microsoft Account and changed the phone number listed [protected] which is my homeland line, to my cell number [protected]. I did this for security reasons, realizing that if I needed to receive a text from Microsoft in the future, they would need a phone number that can receive a text message. When I did this Microsoft gave me a message saying the change might take up to 30 days, but my email access would not be affected. The next morning when I logged in, I was locked out of my account. At the lockout sign-in, Microsoft told me to fill out a verify form. I did. The form asks for basic info, an alternate email account, for you to list 4 recent emails you sent from memory and to remember 4 subject line messages. I filled all of this out. I received a rejection saying I was not myself. I filled out the form now 4 times, each time receiving rejections. I contacted Microsoft customer service on 3/37/21, and had lengthy, very lengthy conversations with them trying to unlock my email account. Both times I was told I had to wait 30 days. Both times the customer service representative told me my security was important. In both conversations I asked them to simply change the account back to the old phone number. They said no. I asked them to call me on both phone numbers to verify I was the same person. They said no. I have two open tickets for this matter. My Microsoft open tickets are as follows: #[protected] #[protected] 1.As of now, I must sit without access to my paid subscription email for 30 days. 2.Representatives that I spoke with at Microsoft cannot tell me tell me what happens in 30 days. Microsoft has given me no written notice to their policy. In fact, they use an automated message to tell me I will have access to my email during a 30 day wait period to change my account phone number. 3. I pay Microsoft to use this email as part of my annual Office 365 subscription. However, since I am locked out of my Microsoft account, I am unable to cancel the upcoming auto renewal on my Microsoft Account. That seems convenient for Microsoft does it not? 4. Is locking a businessperson out of their paid subscription to Office 365 like a ransom ware? It feels like that to me. If any logic is applied to this matter at all, people across the state of Minnesota subscribe to Microsoft Office 365. And of those people many will get updated phone numbers and want or need to change them within their banking, credit, and business. If a Corporation like Microsoft makes policy that results in changing a contact number and informing the consumer it will not affect their Outlook Mail, and then locks them out of their mail, that is fraud
