Mailbox security change

Dear users, at the beginning of October, older authentication methods for Office365 services will be disabled for security reasons. This is a change whose impact on users will vary.

1) Login and password remains the same.

2) This information doesn't apply to users who use Outlook via the web

3) Users using Outlook 2016 and later on their computer experience the change automatically. If you cannot log in to the e-mail even after repeatedly entering the login and password, contact your network administrator.

4) Users using the Thunderbird client for viewing e-mails should also be switched automatically, depending on the version. If you cannot log in to your e-mail even after repeatedly entering the login and password, contact your network administrator.

5) Users of other clients will have to change the settings themselves - only the authentication method will be changed to OAuth in the login settings. If the client does not support this option, contact your network administrator.

6) Users of mobile devices will need to delete the old account and re-enter it. This change might be device specific, or it will depend on your operation system or e-mail cliend. We recommend using Outlook mobile.

Generally, if you repeatedly have problems with logging into your mailbox, try closing and restarting your e-mail client. If this does not help, contact your network administrator and until it is resolved, you can use the web client https://outlook.com/upol.cz
