Employee Email

If you’re communicating on Outlook with over 500 employees, you know firsthand about Outlook email limits. Have no fear! We have all the info about Outlook’s email sending limits and what to do about them.

Many people are surprised when they first encounter limitations on their email sending in Outlook. You’ll quickly discover that you’re only able to send a single email to a fraction of your recipients, and that the limits of Outlook maximum recipients are holding you back. Yikes!

Outlook’s sending limits can hold back your internal communications, adding time and effort to a process that should be quick and easy! If Outlook email limits are a problem your organization is already facing, then your internal communications are in desperate need of optimization.

ContactMonkey is a powerful Mailchimp alternative and best alternative to Staffbase for email tracking and internal communications in Outlook. It enables you to go beyond the email limits imposed by Microsoft on your email newsletters.

How Many Emails Can You Send From Outlook 365?

According to Microsoft, there are different limits on how many emails and newsletters you can send from your Office 365 account.

Outlook restricts you to 10,000 daily recipients. This limit works on a rolling timer, rather than a daily timer which means that your Outlook email recipient limits will reset 24-hours after you’ve reached them, rather than at 12 a.m. the next day. If you wanted to send more than 10,000 emails in a 24-hour period, you would need a third-party app dedicated to mass email sending.

The other limit is for Outlook maximum recipients for a single email or newsletter. The Outlook recipient limit for a single email is 500 people. This restricts the To, Cc, and Outlook Bcc limit. The maximum number of email addresses you can put in the To, Cc, and Bcc fields is 500.

This means that if you wanted to send to a unique group of recipients for which you don’t have a distribution list, you would be limited to 500 recipients.

In large organizations, this limit can add unnecessary time and effort to your internal communication process.

Outlook Email Limits Workarounds

There are a few approaches one can take to avoid error messages in Outlook when sending to a large number of recipients.

Distribution lists can partially solve this problem. A distribution list is a method that enables you to send email to tens of thousands recipients via a single address. It’s super easy to create a distribution list in Outlook, which greatly helps your internal email efforts.

For example, if your company has 64,000 employees, your IT department could create a distribution list that includes any and all of these people. The distribution list would appear as everyone@company.com, for example. This lets you bypass the 10,000 daily Outlook recipient limit.

The problem with distribution lists is that they are difficult to create and edit. This means that if you want to send an email to a unique group of employees, you would need to enter their individual emails into the To, Cc, and Bcc fields.

Here you’ll encounter the other Outlook email limit: you will be restricted to 500 individual emails in those send fields. If you need to send to more than 500 recipients, you’ll need to send multiple emails, which is not ideal:

  • Employees receive information at disparate times
  • Email addresses can be overlooked when entering them manually
  • Multiple emails are more difficult to archive and find in the future

Both of these Outlook maximum recipients limits can negatively impact your internal communications process. If you want to avoid needless time and effort in sending mass emails to your employees, then a dedicated employee engagement software may be your best bet.

Manage Distribution Lists with ContactMonkey

Even though you’ve powered up your distribution lists, there will always be situations in which you need to send email to a unique group of more than 500 recipients not covered by an Outlook distribution list.

Remember, Outlook limits you to 500 recipients in the To, Cc, and Bcc fields.

You could always request your IT department to create a new one, but if you’re in a large company that could take a while!
