Office 365 / Exchange Online Mailbox Size Report Including Mailbox Free Space with PowerShell

Office 365 / Exchange Online Mailbox Size Report Including Mailbox Free Space with PowerShell

I wanted to create an automated alert that would notify me of Office 365 mailboxes that were approaching full, and found a terrific PowerShell reporting script by Ruud (LazyAdmin.nl). If you have not checked out his blog, stop reading now and head on over there. There is a ton of great scripts and write ups! The script connects to your Office 365 environment and exports the following:

  • Display name
  • Primary Email address
  • Mailbox type
  • Last user action time
  • Total mailbox size
  • Mailbox Free Space (NEW!)
  • Deleted item size
  • Item Count
  • Deleted Item Count
  • Issue Warning Size
  • Prohibit Send Receive Quota (max mailbox size)

  • Archive Deleted Item Count
  • Archive warning quota
  • Archive quota

Improved External Email Tagging in Office 365

With the rise of Phishing emails, a popular method to help your users not get phished is to append warnings to emails that either originate outside the organization or if they originate outside the organization and the display name matches that of a internal user. I myself have posted a blog on how to do this and get around the mail flow limitations.

A problem with this method however, is since it prepends a message or warning to the email, users can no longer view previews of the emails either in outlook or on mobile because all they will see is the warning message. A possible solution that I have rolled out several times is to prepend a warning unicode character (⚠️) to the message. The warning symbol was approved as part of Unicode 4.0 in 2003 and added to emoji 1.0 in 2015. As long as the receiving end … Continue...
