Phone number for on our users has changed automatically to +44xxxxx7913

[IBN]

Hello Teams Community,

Please i need your help on this.

The issue is that the number for on our users has changed automatically, please see the screenshot below:

This was previously +44xxxxxx9229 and this same correct number is also on the user’s AD account. We’d like to know why and how this number has changed automatically.

 This is the user's account on-prem:

This is her synced account in Azure:

According to audit logs it hasn’t been updated or changed manually:

so we would like to know:

1. Why is the number different to her AD attribute and Azure properties
2. Why did the number change automatically on her teams account according to our Teams admin portal
