On the first load of your users, Signitic retrieves the information from your connector. This data is loaded once each time it is added to Signitic.
However, when a user is present in Signitic and their information changes in your directory, the user will not be modified in Signitic.
To change this behavior, you have the option to enable data rewriting.
Go to your settings

Go to Settings > Connectors then click on the desired connector.
Enable/disable the data rewriting option

You will find the connectors Source Microsoft 365 or Google Workspace and the following option "Data rewriting".
Each day, your users' information such as their phone or position will be updated from your directory.
Tip : If you have specific cases that you want to handle in Signitic, you can always pin specific fields to avoid this update: See the guide.
