Outlook instructions
Thunderbird instructions
Windows Mail app instructions

Information: We recommend using Outlook as e-mail client so that you can use all features of your Exchange mailbox (such as calendars or address books). When other alternative e-mail clients (Thunderbird, for example) are connected with your Exchange mailbox, the features may be limited and may require add-ons. There is no guarantee that these add-ons will be updated or will work in future. Due to this, the University IT only offers extensive support for Outlook. 

You can also access your Exchange mail box via web browser at https://exchange.uni-mannheim.de if you do not want to install a client on your computer. In this case, please login with your Uni-ID and the corresponding password.

    Outgoing mail server:

    Server

    exchange.uni-mannheim.de

    Port587
    SSLSTARTTLS
    AuthenticationPassword, normal
    User name

    Uni-ID

    Thunderbird will then connect to your new mailbox and synchronize your e-mails. 


    Updating the system folders in Thunderbird
    We recommend setting up the system folders in your e-mail client in such a way that they are identical to the folders of the Microsoft Exchange OWA (Outlook web access). This way, the same folders will be used in the e-mail client and OWA.

    Please proceed as follows to update the system folders:

    1. Please make sure that all Exchange folders are displayed. Click with the right mouse button on the e-mail account and select “Subscribe...”:

    2. Click “Update” (1) in order to receive the latest Exchange folder list. Then check the boxes of the folders that should be displayed in Thunderbird (2). Then click “Subscribe” (3) and then “OK” (4). Now the new folders will be displayed in Thunderbird:

    3. Click with the right mouse button on your e-mail account and select “Settings”:

    4. In our example, we describe how the folder for sent e-mails is updated. In the menu on the left, click “Copies & folders” (1). In the middle, activate the option “Other folder” (2) under “When sending messages automatically”. Then click on the drop down arrow (3) and select the folder “sent elements” (f) under your e-mail account (NOT “Local folder“)

    The system folders should now be displayed correctly, at the latest after you closed and re-started Thunderbird.


    In order to also synchronize your calendar and your contacts, please follow the instructions in the next chapter.

  • Connect the calendar and contacts of your new Exchange mailbox to Thunderbird

    The permanent functionality of these calendar and contacts add-ons depends on the developers of the individual add-ons. If these add-ons are not updated, you may not be able to use them with your Exchange mailbox. In this case, UNIT cannot offer support. Therefore, we expressly recommend the Outlook clients for Windows/Mac or Outlook web client for using your Exchange account.


    In order to synchronize not only your e-mails but also the calendar and contacts of your new Exchange mailbox in Thunderbird, you need to install and set up two add-ons:

    1. Click on the application menu in the upper right corner in Thunderbird and choose the “add-ons” option:


    2. In the window that appears, enter “tbysync” in the search bar at the top and confirm by clicking the “Enter” key:


    3. A tab with search results will appear. First, click on the button “Add to Thunderbird” in the section for the “TbSync” add-on, confirm and repeat the process for the add-on “Provider for Exchange ActiveSync”:


    4. Close the two add-on tabs and switch back to the main window of Thunderbird:


    5. In the lower right corner, click on “TbSync: Leerlauf”:


    6. This will open the  TbSync account management. Then go to the lower left corner and choose “Account actions” -> “Add new account” -> “Exchange-ActiveSync”:


    7. Then select “User-specific configuration” and enter your data. In the field  “User name (e-mail address)” enter your ad\Uni-ID, for example ad\mamuster. Then click on the “Add account” button:


    8. The account will then be added and must be activated. Check the box “Activate and synchronize account”:


    9. Then a  selection menu will open in which you can choose the contents to be synchronized. For your calendar and your contacts, check the boxes “Contacts” and “Calendar”. Then set the periodical synchronization (≥ 5min) and click on the “Synchronize now” button:


    10. Then the elements you selected will be synchronized. If a green tick appears next to your account name, the synchronization has been successful.

    Now you can access your calendar and contacts.

    If you want to search for contacts in the university’s global address books, switch to the address book in Thunderbird, mark your new Exchange account by clicking on it and then search for your contacts in the search bar in the upper right corner:

  • Information and error messages

    Please note that Thunderbird’s functions will be restricted when connected via the IMAP protocol with your new Exchange mailbox. For example, when you create and synchronize your e-mail folders, they will not automatically have the same structure as in your Exchange mailbox. You need to go to the settings to adjust the folder mapping. In this case, UNIT is unable to provide support. In Outlook 365, Outlook 2019, Outlook 2016 and the web client, this will appear automatically.

    Error messages when synchronizing

    If you see error messages when synchronizing:

    • Make sure that Thunderbird is in online mode. If this is not the case, click the button in the lower left corner:
    • If this does not solve your issue, please check your account settings again, by un-checking the box “Activate and synchronize your account” and then switch to the tab “Account settings”.
