we deployed a Partner Community the production org and now a single user is getting all their Chatter email notifications from the Partner Community email sender account instead of the standard Chatter email sender. This is happening just for that one user; all the other users in the org are getting their Chatter emails sent correctly. The affected user is in the System Administrator profile and does happen to be the account the org was set up under. Other users in the same profile are not experiencing the same behavior.
All settings have been checked and verified – can’t find anything that appears to be causing this.
Has anyone run into this or heard of it before? What would cause the Chatter email sender to be different for one user over another?
Any insights would be appreciated.
