A user has reported that he does not get outlook notifications for corresponding work items in his inbox.
All the settings are in place i.e. correct email address maintained in SU01 as well as in Infotype 0105 subtype 010.
Not really sure why he alone does not get any outlook notifications.
I tried sending a new message manually from SAP Inbox to his external mail id and was successful in this (checked SOST).
What might be wrong? Please suggest.
