You’ll see a banner at the top of the message that informs you of any restrictions on the message. If you’re using a different email account or email program, you may receive a notification that you’ve received a protected message and need to take additional action. If you’re using a Microsoft email account in Outlook or Outlook on the web, you shouldn’t have to do anything special to read your message.
If you have a Microsoft account and you’re using the Outlook mobile app, the message should just open. You’ll be redirected to the Gmail sign-in page. Once you sign in, select Allow.

Some email clients and services can’t automatically open protected messages. Which option gives you the Outlook Encrypt button?
Which of the three Outlook email encryption options are available to you depends on who your recipient is and which email account you are using to send encrypted email. The three options and their availability scenarios are:. The best Outlook email encryption option for you among the available ones depends on the ease of use for you and your recipients , available features such as access to encrypted messages outside Outlook, costs, and other capabilities.
The table below summarizes the features to help you choose. If your recipients do use Outlook but you have to purchase certificates for them, this option becomes extremely expensive. This option should primarily be chosen if your recipient’s organization requires it.
The OME option is great if you already use Microsoft email through an Office subscription and do not mind recipients to go through the extra step of requesting a code. In practice this can be a hurdle that many clients may need hand-holding with.
The option to use the Encyro Outlook Addin provides the easiest user experience and is free. Regardless of which option you choose, you can find the setup instructions and the detailed steps to send an encrypted email from Outlook, below. Microsoft’s instructions to encrypt email in Outlook can be a little daunting as the different steps to obtain email encryption certificates and using the available options are split across multiple documents.
Unfortunately, these articles have not been updated to include the easier OME option that newer versions of Outlook provide. Also, most of them show older screenshots from Outlook with the “Get Digital ID” button to obtain email encryption certificates. This button is no longer available in Outlook , Outlook and Outlook ProPlus the version installed with an Office subscription.
In this article, we want to provide the most up to date information to help you make the correct choice for your business email encryption in Outlook, and give you comprehensive setup instructions with screenshots. The sections below walk you through all the setup instructions including the process to obtain the required email encryption certificates.
Buy Certificate: You may obtain a certificate from several certificate authorities. Microsoft’s documentation recommends three certificate authorities CAs :. To purchase, click this Microsoft link and then click on the CA of your choice. Here is a link to obtain a free email security certificate. When you purchase a certificate, you will receive a file containing the certificate and a password that is required to import the certificate. Backup the certificate and password: Make sure you maintain a backup of both the certificate file and the password because in case your computer or hard disk gets damaged and you need to setup Outlook email encryption on a new computer, you will need this same certificate again.
If the certificate is lost, then you will not be able to open your previously sent or received encrypted email. Also, if you change to a new certificate, all your email recipients who have your old certificate will be required to update to the new one, which could be a very laborious process for you.
Import Certificate in Outlook: Once you have purchased and backed up! Your certificate is now imported. Your recipients also need to obtain and import their own certificates. Share your certificate with each recipient: To share your certificate, send a digitally signed message to each email recipient to whom you intend to send encrypted email in the future.
Here is how:. At this point, you have sent your certificate to your contact s. Note that the public key portion of your certificate is sent – so others can encrypt a message that they need to send to you. Only you can decrypt such an encrypted email message sent to you because to decrypt, you need your private key which is imported only within your Outlook application.
Now, to send an encrypted message to a recipient, you need to have their certificate public key portion. Add Recipient’s Certificate to Contact Data: These steps need to be followed for every email recipient who will receive encrypted email from you.
Finish composing your email message and add any attachments. Click Send as usual to send the message. It will be sent encrypted. Any copies of the email message saved on intermediate email servers are also encrypted since only your recipient has the certificate with the private key to decrypt this message.
This vulnerability allows an attacker to intercept your message, and add their own signature impersonating you. While the attacker cannot decrypt your original email, they may be able to decrypt replies and subsequent emails on that email thread.
If you have not yet obtained the certificate for this recipient, then Outlook will refuse to send the message. So if the message is sent, you can be fairly confident that the recipient has the required certificate to open your encrypted email. They may need to be on their desktop computer and open the message in Outlook rather than say on their mobile device.
Your recipient’s Outlook application will automatically decrypt the message for your recipient. If your recipient replies to this email message, the reply will automatically be encrypted assuming your recipient had added your email encryption certificate to their contact data. Once your recipient has performed the initial setup steps described above, they have the required encryption certificates.
They can easily send you encrypted replies by replying to your encrypted email. They can also send you new encrypted emails by following the steps to send an encrypted email described above.
However, if you are considering encryption options for your business email, we recommend this option only for cases where your recipient explicitly asks for such encryption. That is only likely the case if your business or professional practice serves large enterprise clients or government agencies.
If you serve many small businesses or individual clients, it is unlikely that your recipients will have the resources and expertise to purchase and install email encryption certificates. The cost of the certificate is a recurring cost as the certificate needs to be renewed every year or every 2 or 3 years, if you paid for multiple years in advance.
Also, this is the cost for one certificate: you need a certificate for each user at your organization. Your recipients also need to purchase certificates. The OME email encryption option lets you send an encrypted email to any email address. So your recipient need not be using Outlook or have any email encryption certificates installed. The two restrictions to keep in mind are:. To enable Office email encryption the key step is to upgrade your Office subscription to a plan that includes Office Message Encryption.
Alternatively, you may add Azure Information Protection Plan 1 to your O subscription, but this usually works out to be more complex for most users and more expensive as well. The steps are:. When you send an encrypted email using OME as above, your recipient receives an email from you without the actual email content or attachments but with an email body that looks like the one shown below the formatting of the email may look a little different depending on which email application or web-mail interface your recipient is using; the screenshot below is from Gmail.
Your recipient will need to click the button Read the message. The button may show up as a link in certain email applications. Upon clicking that button, your recipient will be taken to a web page that looks like the one below:. Caution: The option to Sign in with a work or school account will only work for your recipient if they have an Office subscription with the same email address as you sent them the message to. This can be confusing for your recipient because clicking the link to Sign in with a work or school account will work even if the recipient’s email is not associated with a relevant Office subscription but after logging in, they will not be able to see your message.
So unless your recipient has an Office subscription with the same email address that you emailed them at, they should click the link Or, sign in with a one-time passcode.
For certain recipient email addresses, those on Gmail or Yahoo! Mail, the above web page will look a little different and they will see a button to login with either Google or Yahoo:. These recipients may click the relevant sign-in option and then login with their Yahoo or Google account.
After your recipient clicks Or, sign in with a one-time passcode , they will be taken to a second web page that looks like so:. At this stage, your recipient will need to switch away from their web browser and go back to their email account to wait for an email from from Microsoft Office Message Encryption MicrosoftOffice messaging. Note that this email comes from Microsoft’s email address and not yours, so your recipient may have to look for it in their spam or junk email folders if it is not found in their email inbox.
Your recipient would copy the passcode from this email and then go back to the web page shown previously that was asking for the passcode to be entered. Once they enter the passcode and click Continue on that web page, they will finally arrive at your secure email message along with any attachments. The web page that shows your encrypted message looks like the one below.
