We have a list in our Sharepoint Online instance, and I'm trying to add an alert for another user. When I do so, I receive this error message:
The following users do not have e-mail addresses specified: -{Name of User} Alerts have been created successfully but these users will not receive notifications until a valid e-mail or mobile addresses have been provided.
I've confirmed through user profiles that the work e-mail address and "SIP Address" has been specified for the user in question and that the user has permissions to the list and parent site. (Creating an alert for myself also works as expected, and these are the two user profile fields that contain my email address)
Thanks very much!
