FAQ e-mail

If you use Outlook with our Exchange Server, this error message may appear:

"Message delivery error to the following recipients or groups

The e-mail address you entered could not be found. Check the recipient's e-mail address and try to send the message again. If the problem persists, please contact your email administrator."

As the receiving address has moved to the Exchange server, Outlook has still saved an old assignment in the "AutoComplete list" in this case.
There are 2 ways to solve the problem:

1. You delete the entire "AutoComplete list"
2. You delete and overwrite the individual entries in the "AutoComplete list"

You should first download the current address book from the server. To do this, please go to "Send/Receive" at the top of the menu, then under "Send/Receive groups" and then click on "Download address book".

If a login window appears repeatedly in Outlook, it is important to first determine which window it is, as this can have various causes:

1. sign-in window from Microsoft 365 or Office 2019 (see screenshot below):

If a Microsoft login window appears, you are probably using Microsoft 365 or Office 2019, in which case you need to sign in with your Microsoft account. If you do not yet have an account, you can create one free of charge via identity management. You can find the instructions here. To do this, use your preferred email address and the password you have set up with Microsoft.

It is also necessary to set a special registry value for Microsoft 365 and Office 2019. You can find the corresponding instructions here.

2. login window of Outlook (screenshot below):

If the login window comes directly from Outlook, make sure that you enter your user name correctly in the format "its-ad\ACCOUNTNAME" (e.g. its-ad\uk000000). If necessary, click on Use another account. If this is not possible, you are probably using Microsoft 365 or Office 2019. In this case, it is necessary to set the corresponding registry value. You can find the instructions here.

3. login window after password change

If the login window continues to appear after a password change, it is possible that old login information is still stored in the client. This must be removed. You can find instructions on how to do this here.

4. group mailboxes:

If the login window appears in connection with a group mailbox, please clarify with the owner of the mailbox whether you are correctly entered as a member of the mailbox.

5. further steps:

If the login still does not work or the window keeps reappearing, please contact the IT coordinator of your (subject) department. If you use a UniKasselClient (UKC), please contact our IT service desk (Tel. 0561 804 5678). Please state your device name and your availability.

Each user has a mailbox (email inbox) in which incoming emails are stored, the so-called "inbox". In addition, directories can be created on the central mail server using the Imap protocol, which also fall under this quota. The inbox and the Imap directories are regularly backed up by the backup service.

You can find more information on the e-mail websites.

If required, you can apply for a quota increase at the IT service desk.

The size of an e-mail message sent or received is limited as follows:

• MIME encoding increases the size of an attached file by a factor of 1.4. (10 MB file => 14 MB e-mail.)

• Larger e-mails should be portioned ("split") or packed ("zip").

The number of recipients that can be specified in an e-mail message is limited as follows:

If more addressees are to be reached, an e-mail distribution list should be used. The ITS operates a central e-mail distribution list that can be used for this purpose.

The number of attachments to an e-mail is limited as follows:
