I am using RT5.0.1 and have a problem with RT removing an email address from a configured user. I Know this because looking at the history of the user it tells me
Fri Jan 14 10:00:00 2022 admin (Admin user) - EmailAddress changed from (no value) to ‘email@example.com’
Mon Jan 17 11:10:02 2022 The RT System itself - EmailAddress changed from ‘firstname.lastname@example.org’ to (no value)
If I put it back again it will be removed again. I do not know whats triggering the removal.
I can see no other errors that would indicate why the ‘System itself’ decided to remove the email address from this active user. This means the user does not get notified about tickets he is watching.
Whats causing the System to remove this valid email address and how can I fix it.
