Our team has been using Gmail delegation through GAM to allow various team members access to accounts. Recently, when we delegated access to an account, the account being delegated received a notification stating that the user now has delegated access, along with a link to review delegation settings. This notification is unexpected because the account was not actually delegated to the receiving user. In the past, we would delegate without any notifications needed on either user's part. A colleague experienced the same issue while running the same command. We haven't changed any delegation settings in the Google Admin panel. Has anyone else encountered this issue, or do you know if there have been any changes made to how delegations work? It's possible there might be a bug on Google's end. The command we ran was: gam user delegate to . After reaching out to Google, they confirmed that this notification is an intended change and not something we can manually dismiss. It will automatically disappear after a certain period.

We're experiencing the same thing this week. Now, delegation sends out user notifications and doesn't complete automatically unless the receiving user confirms. No changes on our side either, so it seems like a recent update from Google rather than an issue with GAM.
Ugh! I just ran into this myself! Our HR team thinks we messed something up because the end-user got notified. Do you know if there's any way to disable that message?

I was testing this out and found that the delegation does eventually complete after about 5 minutes. The notification sticks around, though. You might want to check if the delegation goes through after a bit of time!
