We are getting lots of reports of this from users. Is anyone else experiencing it?
It seems that if a user logs in and stays on the mail tab, they never get their calendar reminders. If they log in, click on the calendar and return to the mail tab, then the reminders work fine.
I found this bug for Desktop...
Bug 32162 - Reminder didn't pop up until I opened the calendar
...but it seems to be affecting us on the 5.0.9 Web Client as well.
We think maybe the "lazy loading" feature is set so that reminders don't happen unless/until the calendar is selected (and Zimbra loads that module).
Can anyone else confirm that this is happening?
