Using Outlook for iOS in business environments for email and scheduling
Hello @Davies Holly,
I'm sorry to hear about your situation.
To help provide the most accurate and effective solution, could you please share a bit more information about your setup?
- Since this question is posted under the Business category, can you confirm whether you're signing in with a work or school account or a personal account (such as Outlook.com, Hotmail, Gmail, Yahoo, etc.)?
- Do you still have access to your old phone, and if so, is the Microsoft Authenticator app still installed and able to receive notifications or generate verification codes?
- Does this issue only occur on Outlook, or also on other Office apps (like Word, Excel,...)?
- If this is a work or school account, does the account have any administrative role in the organization (Global Admin, User Admin, etc.)? Also, is there another administrator available in the tenant?
- How was your Microsoft 365 subscription obtained: directly from Microsoft or through a partner/reseller?
This information will help us determine the available recovery options and whether the authentication methods can be reset or reconfigured.
Thank you, and I look forward to your response.
