Hi, Ahmed,
Since this issue is more related to Outlook, I'm moving it to a Outlook forum:
https://social.technet.microsoft.com/Forums/office/en-US/home?forum=outlook
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn
from your interaction with us. Thank you for your understanding.
Best Regards
Jerry
