Outlook 365 - Group sending email "send as" doesnot working
Adin_Calkic Definitely yes. Thanks a lot. But I just found the solution of my problem....It was cache I guess....the field "FROM" on the email must be firstly taken from global address list and then it is working. See below....

SOLUTION
To resolve this issue, follow these steps:
In the new email message in Outlook, click From, and then click Other Email Address.
In the Send From Other E-mail Address window, click From, change the address book to the global address list (GAL), and then select the user to whose mailbox you were granted Send As permissions. For example, select User B.
