Email security for Outlook
strong encryption of emails and files
Every day your business exchanges a wealth of data with customers, suppliers and partners. A big part of this communication takes place via email and Outlook and is constructed in your Office applications.
However, often the information is highly confidential or captured in files that are simply too big to send via email. So what happens then?
There are many different ways to get around this problem but our advice is to use the tools you already have!
Cryptshare for Office 365 & Outlook enables you to
- secure and share confidential emails and files without size restrictions
- completely ad hoc via your regular email directly from your familiar Outlook interface.
By solving these known problems in email Cryptshare provides the fastest and most simple solution.

How to send a large file in Outlook
Get rid of email attachment file size limitations in Outlook
From time to time, most users need to send large files with Outlook.
When you try to send a large email in Outlook, you are faced with two file size limitations:
- The file size limit set by the mail server of your email recipient
- The file size limits set by your Outlook itself.
Outlook limits the size of email attachments to a total of 20 MB. It makes no difference whether a single file with 20 MB or several smaller files are attached;
If the total size of the email attachment exceeds 20 MB, a warning message will appear that is well-known by most Outlook users:
Now one could certainly discuss whether one can still speak of a "large file" at 20 MB nowadays. Furthermore, this file size limit for email attachments dates back to the previous millennium.
Nevertheless, these restrictions give legitimate hints to problems resulting from large email attachments, no matter if with or without Outlook:
- Large emails (or emails with large attachments) cause your email recipients' storage quotas to become very busy
- Large attachments also burden your own email storage quota (for example, Exchange) by storing the data in the Sent Items folder.
If you then add yourself, or perhaps work colleagues, to CC/BCC, the memory consumption can increase many times over again.
With our Outlook add-in "Cryptshare for Outlook", you can create your emails in Outlook as you are used to.
It extends Outlooks capabilities so you can attach very large files to your message, up to multiple gigabyte.
You don't have to take care about attachment file size limitations in Outlook anymore! The Cryptshare Attachment-Manager will be activated automatically, when the total attachment file size exceeds a previously defined threshold (5 MB by default).
The files are then not transported via email anymore, but via your Cryptshare server. Even taking the load off your and the recipient's email system. Only your system administrator can limit the size by configuration.
We recommend, to watch our video (File attachment handling starts at 1:05) to see how easy it is to send large files in Outlook with Cryptshare.
How to attach a folder to an email message in Outlook
With Cryptshare you can add entire folders, including files and subfolders to email by dragging them to the sidebar.
The Outlook add-in will suggest to create a ZIP archive in order to transfer the folder structure in its original form, including all the files in that folder and subfolders. You have the option to give the zip file a name and start with creating the zip archive by clicking "Yes".
So you do not have to create the ZIP archive yourself beforehand to send entire folder structures by email.
By selecting the "No" option, all files saved in the folder structure are appended directly to the sidebar. The structure of the folders will be lost then.
Email classification in Outlook
Data classification is an important compliance standard asked for by the GDPR.
In addition to email encryption, Cryptshare offers the capability to classify data before transmission with Microsoft Outlook.
Keep on track of your secure data transfers
Everything under control
Don’t lose track of those important items! With an integrated transfer manager as a side bar into Outlook you keep full control. It shows the status of all transfers you have sent and received via Cryptshare for Outlook. Since sending a lot of items means having to manage many different passwords, an option lets you check all corresponding passwords you’ve assigned. In order to prevent storage space problems in your Outlook inbox, large files received via Cryptshare can be detached from the original mail and stored on your hard drive. The side bar provides a clear overview at all times, convenient and secure. A feature you’ll never want to do without again.
Recall email in Outlook
This happens to everyone and can turn into a real risk, because such a mistake by any employee can become a security risk, especially for valuable data. How can you avoid accidental leaks or loss of information such as
- Trade secrets
- Personal data
- Patient data
- Constructional plans
With Cryptshare's Revoke feature, human error can be corrected even after the fact. This offers your employees a safety tool that alleviates the stress in cases where files were sent by mistake. At the same time, you significantly reduce the overall risk of data loss for your company.
Password protected email and attachments in Outlook
Every email sent via Cryptshare is encrypted and protected with a password.
You do not need to remember these passwords - you can view them at any time in the Cryptshare for Outlook transfer manager.
This password is used to protect the confidential email or mail attachment and can be set as follows
This option will generate a secure password fulfilling all the requirements that the administrator has set.
The password will be shown to the user who can then copy it to the clipboard.
This option allows you to set a password manually. The administrator can specify how secure the password has to be by defining which characteristics the password needs to fulfill.
This option allows you to send emails without having to deal with passwords. Cryptshare still generates a secure password in the background and uses it to encrypt the transfer.
But the password will be sent to the recipient in plain text as part of the download link in the notification email. So security is significantly lower.
After activation, the Cryptshare QUICK Technology takes care of all passwords for the exchanges between communication partners in the background.
