Hi All, 1. We have user named user1, whose Mailbox is getting disabled today. 2.The user will be in the disabled state for 3 months 3. Mailbox will be deleted as per retention policy period settings of 30 days. Query: Once the user mailbox has been disabled (Disconnected) the user email address user1@domain.com will be again available for any new user But how to avoid this --I mean how to make user1@domain.com not available for let say 6 months so that the email address cannot be re-used. Here the issue is there will be so many issues 1. The emails destined to old user may reach new user with same email address 2. Security compliance issue So Please advice on this. Manju

Hi, You could create a dummy user account and add the e-mail address to that account (remove it after 6 months). Leif

Hi, As Leif said you can achieve this... or even you can create a dummy OU and create a contact for those deleting users... Thanks & Regards, Kottees **** Please mark as an answer if it is really helps you.

Hello, If you do not want other users to see the specific user in Gal, you can hide it in AD then clear up the Nick Name Cache NK2 file on the Outlook client. Thanks, Simon
