Plus Addressing in Exchange Online
During Ignite 2020, Microsoft announced that plus addressing was coming to Exchange Online. Plus addressing allows users to create their own unique email addresses by leveraging a plus sign in their email address—for example, email@example.com. Anything after the plus sign is completely at the discretion of the user.
This becomes particularly useful when you want to target newsletters to a unique email address, especially when configuring inbox rules. It is also useful to determine who might have sold or leaked your email address.
To leverage this feature, an administrator must enable it globally (by default, it is disabled). To do this, log onto Exchange Online PowerShell. First, let’s verify if plus addressing is disabled. We do this with the following command.
C:\> Get-OrganizationConfig | FL AllowPlusAddressInRecipients AllowPlusAddressInRecipients : False
From our output, we can see that plus addressing is disabled in our tenant. To enable, run the following command.
C:\> Set-OrganizationConfig -AllowPlusAddressInRecipients $true
To confirm the setting has taken effect, rerun Get-OrganizationConfig.
Users can then start leveraging plus addresses. Emails addressed to a plus address will appear in the user’s inbox without any further user intervention. From there, the user can build inbox rules for the plus addresses if they desire.[Read more…] about Exchange Online Updates (December 2020)

Microsoft hosted its annual conference this September. However, unlike prior Ignite conferences, this one was impacted by COVID-19. As a result, Microsoft took its massive conference, typically attended by tens of thousands of individuals, and converted it into a digital online experience.
At 1,222 sessions, here are the top 15 sessions I think every Exchange admin should watch.
Tip: I have included extensive notes for each session and the time each topic starts. You can expand the session notes under each video by clicking “Show more session notes.”[Read more…] about 15 Ignite sessions every Exchange admin should see (2020 Edition)

As always, test these updates in a lab first! I recommend checking out this 7-part guide on configuring Exchange in your lab. It doesn’t take much to get one going.
The updates are as follows:
So, what’s new in these Cumulative Updates?
In this series of cumulative updates, Microsoft added thirteen new blocked file types for use with the OWA Mailbox Policy. The additions included several scripting extensions, including many python file types such as .py, .pyc, and .pyo. For a full list of the new extensions, check the following article.
These cumulative updates also correct an issue when using the Restore-RecoverableItems command in a pipe. We covered the cloud-exclusive GUI version of this command in an article earlier this week. Be sure to check it out.
Companies leveraging Hybrid Modern Authentication will also want to take note of these updates as they fix unexpected authentication prompts during certificate rollovers.
Customers leveraging Edge Transport will also want to take note as these updates resolve a situation where Edge Transport servers may become unresponsive due to deadlock in the shadow redundancy manager.[Read more…] about Exchange Cumulative Updates (June 2020)
Recover deleted mail using the new Exchange Admin Center in Office 365
In the last quarterly update, we covered the new Exchange Admin Center in Office 365. Exclusive to the new admin center is the ability to recover deleted items back into a user’s mailbox. This process has been available using PowerShell for some time.
Keep in mind you can only recover up to the limit of your single item recovery policy. By default, this is 14 days in Office 365, but can be increased to 30 days (although you will need to set this ahead of time).
You can read more about how to recover deleted items in the following article.
Preventing Reply-All Storms in Exchange Online
Microsoft has added a new feature to combat reply-all storms. These storms are particularly prevalent when numerous people execute a reply-all to a massive distribution list.
Microsoft’s initial reply-all protection will block replies to an email thread for 4 hours if it detects more than ten reply-all messages within 60 minutes to a thread with over 5,000 recipients.
The eleventh sender will receive a non-delivery report titled Reply-All Storm Protection with the reason the message was blocked.[Read more…] about Exchange Online Updates (June 2020)
On February 29th I had the great pleasure of being a guest on the RunAs Radio podcast. I joined host Richard Campbell to discuss all the new security requirements coming to Exchange Online, specifically around the new modern authentication requirement and the deprecation of TLS 1.0 and 1.1.[Read more…] about RunAs Radio #684 – Exchange in 2020 with Gareth Gudger
