Get all Exchange SMTP addresses and export to CSV
Heyo and Happy New Year!
A new year brings even more acquisitions and as such, the ongoing desire to automate as many of these tasks as possible. Our latest one is nice because they are a decent sized company, running Microsoft products, namely Exchange. As with nearly all acquisitions, these companies have multiple aliases for a single mailbox. This particular one has roughly 6 different domains/aliases for each user. Thus, I created this script.
This script will pull all of the mailboxes from the Exchange org, select all the SMTP addresses and export all of the data to a spreadsheet. Also, we break up all of the SMTP addresses with a semicolon so that we can later import those addresses to Exchange. Simply put, my import process uses a semicolon to decipher different addresses, so the export process should work upon that base.
