I am having issues with Barracuda Message Center and recipients being able to pick up their messages. Most users when trying to log in the first time get nothing. Some clients still use windows XP with I.E. 8 and they have to use the legacy website however some can't even use that. Is anyone else experiencing issues with the end users getting their emails? Is the some sort of instruction sheet availible for users to provide their clients on how to use it?
