HI Gwen
We have outlook 2010 and the invite.ics files that get attached to the emails work fine so i can't help much with that - sounds like an Outlook setting more than a Moodle/f2F issue.
For your second question about the error message, this post has a (lengthy) description about getting the manager approval process working:
https://moodle.org/mod/forum/discuss.php?d=205966
As a quick summary of my understanding
- You need a user profile field for the manager email with short name 'mangersemail'
- This needs to be setup with an email address for all users - either by collecting it as a required field in signup, getting users to add it to their profile or some other method such as using a query to assign a default address - if this field is not populated you get the message you mentioned
-
If the profile field is populated it gets displayed as an editable field in the f2f activity allowing it be changed (note that it is a once off change for this activity sign up - it does NOT update the profile value - that would need to be done via Edit Profile)
We use F2F but as we can't reliably maintain the manager profile field we have it turned off:
- Managers email unticked in Site Admin/plugins/activity modules/face to face
- no manager approval or send confirmation fields ticked when the F2F activity is set up
