Frequently Asked Questions (FAQs)

Q1: Can I change my phone number on Outlook without logging in?

No, changing your phone number on Outlook requires you to log in to your account. This ensures the security of your account and protects your personal information from unauthorized changes.

Q2: How long does it take for the new phone number to be updated on Outlook?

The time it takes for the new phone number to be updated on Outlook may vary. In most cases, the changes should take effect immediately after you’ve successfully saved and verified the new phone number. However, there may be occasional delays due to network or system updates.

Q3: Will changing my phone number on Outlook affect my other Microsoft accounts?

Changing your phone number on Outlook only affects your Outlook account. If you have other Microsoft accounts linked to your Outlook account, such as Xbox or Office, the phone number change will not automatically update those accounts. You may need to update the phone number separately for each linked account if necessary.
