I have been asked to standardise email addresses across my organisation of approx. 10000 mailboxes. Currently, there is a mismatch of email addresses as over time, when creating accounts nothing was followed to standardise.
I would like to know the easiest way to convert all accounts to email@example.com. I would also like to be able to specify what happens if there are two users with the same name.
Are there any scripts I should be running to verify health of addresses before hand? Is there anything to look out for gathered from your experience?
I imagine I need to verify that all users have the check box enabled to update the recipient policy.
Any idea how long this would take to run on 10000 users? would there be any advantage of running this out of hours based on server resources used to run this?
what errors have you all come across when running this? (I need to be pro active prior to running this)
Thanks again for the answers so far!
