We have hundreds of projects and hundreds of users. A few users this week are reporting that they are not receiving email notifications on tickets when they are assigned or comments are made. All permissions and notifications are correct in the projects. I have triple checked their Outlook for Rules, Junk or sent to other folders and cannot find any there.
The strange one for these users is that they receive a comment notification when the @mention is used for them. If someone does not use the @mention, no notification is sent. These users are on separate projects.
Appreciate any help.
