Commenting with Mentions in Channels
In AB Projects, a task's comments and its Microsoft Teams thread are two ends of the same conversation. Comments you write on a task are posted into the linked Teams channel, and replies people type in that Teams thread come back as comments on the task — so the discussion stays together no matter where it happens.
Writing a comment and mentioning people
- Open a task and go to its Comments section.
- Write your comment in the rich-text editor (formatting and image upload are supported).
- Below the editor is a "Mention in Teams notification" picker — a row of member chips. Click a member's chip to select them; click again to deselect.
- Selected members are @mentioned in the Teams channel post, so they get Teams' normal notification. Only members who have a Teams identity in this project appear in the picker (people who can't be @mentioned in Teams aren't listed).
How comments flow to Teams — and back
- Every comment is posted to the linked Teams channel, not just the first one. The first comment on a task starts the thread (an Adaptive Card with the task details); each later comment is posted as a reply in that same thread, so the whole discussion is threaded under the task.
- Replies in Teams sync back. When someone replies in the task's Teams thread, that reply is added to the task as a comment automatically — the conversation stays complete on both sides.
- If a Teams replier isn't a registered AB Projects user yet, their reply is still captured as a comment (noted as coming from an unregistered user), and the bot invites them to register so future comments link to their profile.
- Mentioned members are @mentioned in the Teams post itself, so notification happens through Teams natively rather than a separate alert system.
Best practices
- Mention only the people who need to act or weigh in — each mention is a real Teams notification, so use it deliberately.
- Keep discussion in the task's comment thread (in AB Projects or by replying in the Teams thread) rather than starting a separate channel message — either way it stays attached to the task.
- Review your selected mention chips before posting so you don't notify people unnecessarily.
- Because the Teams thread and the task comments are kept in sync, you can follow up wherever is convenient and nothing gets lost.
By tying every comment to both the task and its Teams thread — in both directions — AB Projects keeps task conversations precise, visible, and never split across two places.
