If you're using Outlook, two questions have probably crossed your mind: what is the maximum size of an email, and how can I send a larger file?
These are completely legitimate concerns! Whether for personal or professional use, knowing the sending limits and being able to manage the size of your emails is essential for optimal communication. And honestly, what’s more frustrating than an error message telling you your email didn't send because of a file that's too large?
No more headaches! Today, we’ll tell you everything you need to know about the maximum email size in Outlook, along with tips for sending large attachments.
So, what is the maximum email size in Outlook? Actually, Microsoft’s email service has defined several limits based on the type of account (free or paid) and the version of Outlook you're using.
A note about the said size: it includes not only your attachment but also the text and other elements embedded in the email, such as your professional email signature. Generally, however, these last elements are negligible compared to the size of the attachment.
But why impose a size limit on emails and attachments in Outlook? Don't see this as a Microsoft conspiracy to make your life more difficult! In fact, the company only has your best interests at heart.
This size limit has several reasons, including:
Speaking of UX, do you know what can be designed intuitively and in the blink of an eye? Your email signature! Find out how to create your Outlook email signature seamlessly.
In addition to the email size limit, Outlook imposes other restrictions to ensure security, proper service functioning, and a smooth experience. Among these restrictions is the daily sending and receiving limit.
The third limitation imposed by Outlook to protect its users and ensure a smooth experience is the maximum number of recipients per email.
Once again, this is a variable figure depending on the type of account.
For free accounts, the recipient limit is not specified by Microsoft but is certainly lower.
To send an email to a large number of people, regardless of your Outlook account, the best solution is to create a contact group.
Here’s how to do it:
Additional tip for your communication campaign to be a real success: add an impactful Outlook signature with your company’s branding to your email!
Can't quite accept the size limit imposed by Outlook? No problem – there are several methods to send emails with larger attachments.
Zip! In the time it takes to say it, you can compress your large file into a zip file using dedicated software. WinZip or 7-Zip, for example, are two very effective free services.
Another practical and quick option for sending your larger files is to use a file-sharing service. With Dropbox or WeTransfer, among others, upload your photo/video/experimental art film of 4 hours, then insert the link into your email, and you’re good to go!
For its subscribers, Microsoft offers a file-sharing and real-time collaboration cloud service called OneDrive. With this tool easily accessible from your email, there's no need to get frustrated by error messages due to a file that's too large. Simply upload the file to OneDrive, and your collaborators will have immediate access.
Want to send a file exceeding the standard 25MB limit in an Outlook email? In addition to the methods mentioned below, you can also send the file in multiple parts, if the nature of the file allows it (for example, a video split into several parts).
By the way, if you have a paid account for your professional activity, don’t forget to create your Outlook 365 signature to enhance your communication.

Yes, with the 'Campaigns' offer, it is possible to track the number of clicks on the email signatures of all your employees in the 'Statistics' area of the platform.
You can then access a detailed or global view of the number of clicks on the email signatures of each employee. You can use the search option to target a specific signature or a given period. Finally, you have the possibility to export all statistics to an Excel document.
If you launch campaigns with banners inserted in your email signatures, you can also access their performance via this same space.
With Letsignit, you can easily add social network icons in your collaborators' email signatures and link to your company pages. Also, our "attributes" feature allows you to manage personalized URLs for each of your collaborators such as their individual LinkedIn profile.
And that's not all: you can add links to an appointment-setting application, allow your customers to leave reviews easily, and integrate our 'Chat on Teams' widget to let anyone start a discussion via Microsoft Teams chat.
It’s up to you! As an administrator of the Letsignit platform, you choose whether or not to grant modification rights to your employees. These permissions are managed on an attribute-by-attribute basis, which means that you can decide to allow the employee to change their phone number, but not the address of your premises, for example.
This feature applies to all attributes in your directory, including custom attributes created on Letsignit. When your employees change one or more attributes, your directory is obviously not affected.
It often happens that employees make their email signature their own: custom format, bad fonts, colors inconsistent with the brand standards... all of this has an impact on your brand!
A consistent visual identity is considered authentic and outperforms a perceived weak one by 20%. And, your customers are 2.4 times more likely to buy your products.
With Letsignit, take back control over your brand identity by standardizing all your email signatures. Our tool has many features that allow you to customize your signatures by department, by audience or by subsidiary. Not to mention the possibility of carrying out campaigns within your email signatures thanks to our Campaign offer.
