How can I login if a colleague left our company and the account is only accessible under his e-mail?
For security reasons we cannot update the e-mail from an account when this is requested by a non-authorised user.
You will need to contact your colleague and ask for the password or ask him/her to change the e-mail of the account to your e-mail address.
If you cannot reach your colleague, you will need to reset the password.
If you are using an e-mail under the same domain, please contact your IT Team or sysadmin to receive the password recovery e-mail. They will be able to access or redirect the contents of the orginal e-mail address.
