i have a user that keeps getting delay notifications and eventually gets an NDR when sending an invite from her calendar to an external recipient. the NDR she eventually receives is:
Subject: subject subject
did not reach the following recipient(s):
firstname.lastname@example.org on Sat, 25 Apr 2009 13:13:53 -0400
Could not deliver the message in the time limit specified. Please
retry or contact your administrator.
this only happens when sending invites from her calendar not emails, her emails get there without any issues. any help with this would be great, thank you.
