No – users cannot change their own email address.
Only admins can update a user’s email address on their behalf.
How to Change a User’s Email Address
Before proceeding, we recommend verifying the user’s new email address by emailing them and requesting a response. This ensures that the users's email is accurate and that the user will receive important information such as invoices once the address is updated.
Once verified:
Go to Users & Groups > Users
Use the filters to locate the user
Click on the user’s username to open their profile
Navigate to the Edit tab
Update the Email field with the new address
Click Save
The user will now receive system emails to their new email address.
