user cannot remove delegate on calendar

[arminhaaf]

after importing a user from an old server (with other mailnode name) to a new server
a user cannot remove a delegate

my assumption is the the delegate is bound to the old mail node name

This leads to a problem that on inviting this user a error message is generated that the delegate is not reachable

Is there a possibility to remove a delegate other than on the webmail?

Thanx

I would suggest trying this with Outlook and see what happens.
