Last year, Google announced the ability to see when someone is out of office in Gmail, specifically when composing a new email or Hangouts Chat. Now, they’re expanding that functionality to more places in Gmail on the web, like when you’re hovering over someone’s name in your inbox or in the “To” or “From” line in an email.
This feature gives visibility to your time out of office in more places across G Suite, making it clear to senders the appropriate time to message you.
These notices will automatically appear when anyone whose calendar you have access to has an out of office event scheduled. Use the Google Help Center to learn more about disabling the sharing of availability information to other G Suite apps.
According to Google, this feature is available now in the U-M domain.
