In some cases, the invitation e-mail will be marked as spam by your e-mail server, or ithe e-mail server will block senders with the name "noreply".
This also affects e-mails with unread message notifications.
- If you find the e-mail in your spamfolder, you can add firstname.lastname@example.org to your contact list. This can be done manually or by adding business cards
- If the e-mails are blocked by the e-mail server, you must contact your IT-department to whitelist the adress email@example.com
