Error message "The incoming mail server is already in use"

If you have already created a mail account in Thunderbird with the default mail address benutzername@(smail.)uni-koeln.de, you cannot set up another mail account with your alias address in the way described above. This applies to all types of alias addresses, i.e.

  • vorname.nachname@uni-koeln.de or v.nachname@uni-koeln.de for personal accounts
  • bezeichnung@einrichtung.uni-koeln.de for aliases in virtual mail domains
  • vorname.nachname@smail.uni-koeln.de or v.nachname@smail.uni-koeln.de for student accounts

In this case, you will receive the message The incoming mail server is already in use when you try to set up the mail account.

This is because the alias address is only a reference to the existing e-mail account, but not an independent e-mail account that you could query separately. All e-mail messages, regardless of whether they are sent to the standard e-mail address or to the alias address, end up in the same inbox folder.

If you receive the message The incoming mail server is already in use, please consider which of the following two alternatives is the most suitable for you:

  • Enlarged view:
    In the menu bar, click either on Tools->Account settings or on the three horizontal lines at the top right and then on Account settings.
  • Enlarged view:
    If you have several accounts, check whether you have selected the correct account. You can now adjust the email alias under Default identity.

  • If you want all emails to have the alias address as the sender address in future, change the email address of the account.
    To do this, select Account settings from the Tools menu in Thunderbird. (If the menu bar is hidden, click on the three dashes, Settings, Account settings at the top right instead.)
    In the new window on the left-hand side, select the relevant email account if you have set up more than one.
    On the right-hand side, you can then enter the alias address instead of the previous address in the Email address field. Save the change by clicking on the OK button.
  • However, if you would like to be able to choose whether a specific message should be sent with the alias address or the default sender address, create another identity for the mail account instead. To do this, follow the instructions for setting up identities in Thunderbird.

More than synchronizing mails

By setting up an e-mail account in Thunderbird as an IMAP account, you can also access your stock of e-mails from different devices and always have a consistent view of the status of your e-mail messages, for example, whether they have already been read, answered or forwarded.

In addition to e-mails, you can also use Thunderbird to synchronise appointments (calendar information) and task lists across multiple devices. Follow our instructions for calendar synchronisation if you also want to have this data uniformly available on all devices.
