2. Product

When you start a new group chat, you can add a title. When a group chat already exists, please open the chat and press the group administration icon on the top right. There you can find an option to edit the title of the group chat.

You can find an overview of all chat members via the chat menu under 'Members'. You can access the chat menu in the respective chat via the icon in the top right corner.

Chats cannot be deleted, you can either leave a chat or archive it.

If you archive a chat in the message inbox overview, this chat will be removed from the overview until you receive messages in this chat again.

On the other hand, if you leave a chat, you will no longer receive messages in that chat. Leaving a chat is final and cannot be undone.

Next to the text input field for messages you will find a plus symbol, which opens a menu for selecting various digital contents. Please select the desired content, e.g. choose a photo from the photo album, and then press "Send".

In Teamwire, instead of an online status, there is the read confirmation. Please scroll down as far as possible in a chat, above your text input field you will now find a line with an eye symbol under the last message of the chat. The profile pictures next to the eye show you which chat members have already read the last message.

If your Teamwire administrator has not disabled this feature, you can disable your own read receipts via the settings.

Teamwire is designed for team communication - create group chats with your colleagues with whom you communicate regularly. Since Teamwire offers the possibility to customize the title of group chats, you can also create several different, e.g. topic-based chats with one group.

You can define your own groups (similar to email lists) in the "Contacts" menu - these groups are so-called 'lists' and allow you to start new group chats with a certain, selected group of recipients, which you have previously defined as a list yourself, with one click or to extend existing chats, provided you are a chat administrator.

In addition, Teamwire also provides so-called circles that you can use to create or expand chats. Circles are groups preconfigured by your IT administrator, so the members of the circles are already predefined (e.g. your teams, project groups, departments, etc.).

Both lists and circles can also be used to extend existing chats - add additional members via the chat settings menu if you are a chat administrator.

You can create group chats for colleagues with whom you communicate regularly (e.g. your teams, project groups, departments, etc.).


You can also define groups (similar to email lists) in the "Groups" menu. These groups allow you to start new group chats with a selected group of recipients with one click.


Furthermore, your IT administrator can preconfigure lists for you. These groups will then also appear in the Groups menu.
