Add Alternate Email Address or Recovery Email Address for Office365 Administrator

In Office365, depending on the admin role of an account you may want to add an alternate email address for password recovery. This is a basically a self-service password reset for Administrators of Office365.

Quick way to do this is with PowerShell:

If this setting is unset for an administrator, Office365 gives you a nice reminder about adding an alternate email address in case your primary account gets locked out.

You can add this information when first setting up the account:

It can also be added for an existing admin user by going to the Gear, Office 365 settings, and edit your settings in the ‘me’ section, you can enter your mobile phone number and alternate email there.

Excel: Check email addresses in bulk if format is correct or not

So had a request today to clean up email addresses as some of them were not valid. This was needed for over 1500 email addresses.

So used the formula below and was able to find all addresses that were “FALSE”. I filtered them out and was able to fix them as needed.

Here’s what you need to do:

If your e-mails are in A column, go in the B column and in the B1 cell and copy paste this code:

Then, go down and left on the B1 cell so you can copy and paste the code to the other cells.  For all the valid e-mails, it will give you ‘TRUE’ and for the invalid ‘FALSE’.
