Without wasting any time, let’s start.

Why Do I Don’t Have Permission to Send Email Error Occur in Outlook?

You will see inadequate permission errors while sending an email because of not having proper send on behalf permission, typing an incorrect email address, and not updating the offline address books after any changes. Also, the Microsoft server plays a role in having an email sending error.

Before jumping to the solutions, it’s essential to learn about the reasons to understand the error better. This passage will help you to understand the causes and make the resolutions easy.

Here are the reasons behind you don’t have permission to send an email error:

Insufficient Send on Behalf Permission

Delegates can send emails on behalf of other recipients with the send on behalf feature. The owner needs to give proper permission to access the mailbox. There are multiple authorization settings that can be modified.

You are facing the error because your Outlook account may not have enough permission to send a message on behalf of the recipients.

Microsoft Server is Down

Microsoft is widely known for its well-managed server. However, the server or a single service can go down due to an outage and heavy pressure. If the Outlook service is down, you will receive an error message while sending an email.

Typed Email Incorrectly

It’s very typical for people to make a mistake. There can be a typing mistake when entering the recipient’s email address. Outlook will send you a non-delivery report message if no user has the same email address.

Address Book isn’t Updated

The address book is necessary for granting send on behalf permission. Also, it’s required to add or remove shared mailboxes from your Outlook account. Outdated or incorrect address books can show errors while sending a message with another email address.

This is irritating when you can’t send emails or don’t have proper permission to send emails on behalf of others. A lot of users find it difficult to fix the error. But, the process is very effortless, and you will be able to fix it without difficulty after reading the full article.

How to Fix I Don’t Have Permission to Send Email Error in Outlook

Here are the ways to fix I don’t have permission to send email error in Outlook:

1. Granting Send on Behalf Permission

Send on behalf feature permits a delegate to send an email on behalf of the owner. Delegates can’t access the mailbox if additional permission isn’t provided. The recipient will see both the delegate’s email address and the owner’s.

Necessary permissions are required to send emails on behalf of other users. In most cases, granting enough authorization solves the issue with insufficient permission to send an email error. Learn more about the granting procedures from the article below.

Here are the procedures to grant on behalf permission:

  • Launch the Microsoft Outlook Application on PC.
  • Go to File.
  • Navigate to Info.
  • Click on the Account Settings.
  • Press on Delegate Access. delegate-access
  • Click on the Add button. add-delegate
  • Select the mailbox from the address book.
  • Click on OK. ok-delegate
  • Grant the permission level for calendar, task, inbox, contacts, and notes.
  • Press on the OK button to confirm. confirm-delegate

You can grant read and write access to the delegate from the permission settings. Choose None if you don’t want to permit to view or write.

After granting the permission, the delegate can choose the account while sending a new email. Follow the steps to send emails on behalf of others.

Here are the steps to send emails on behalf of others:

  • Go to Outlook apps.
  • Click on New Email.
  • Press the From button. outlook-from-button
  • Select the Other E-mail Address option.
  • Type the email address and click on OK. outlook-other-email
  • Send the email.

After receiving the email, the recipient will see the From field as an [Delegate] on behalf of [Owner].

2. Check Service Status

You won’t be able to send messages from Outlook if the server is down or the message service is currently unreachable. Visit Service Portal to see the server status. If the server is down, wait for it to go normal.

3. Type Email Address Properly

When you mistype an email address, the message may be sent successfully because there is a person with the same email address. But, the email bounces back with an NDR or non-delivery report if the email address doesn’t exist or is unavailable under the domain.

In that case, Outlook may show you an error report saying you don’t have permission to send an email to the recipient.

4. Ensure Email Sending Rights

School, company, or large organization grants different permission to every user depending on their responsibilities. You may have access to send emails only to the people inside your organization or domain.

Also, some users may not have email sending permission. You will receive a non-delivery report if trying to send emails to the recipient outside of your authorization. Contact technical support in your company if you have incorrect permission.

5. Update Offline Address Book Manually

OAB or offline address book is a downloaded copy of the user’s email address, allowing the user to access them when disconnected from the Exchange Server. The Send on behalf feature won’t work correctly if your address book isn’t updated.

You must manually update the offline address book to sync with the latest changes. Find the manual updating process from the steps below.

Here are the steps to update the offline address book manually:

  • Open Outlook application.
  • Go to the Send / Receive tab.
  • Click on Send/Receive Groups.
  • Press on the Download Address Book. download-address-book

The offline address book updates automatically unless the changes are larger than 12.5% of the total OAB size.

6. Remove and Re-Add Shared Mailbox

The delegate must add the shared mailbox to his Outlook to access the data. The shared mailbox may have some issues while adding or isn’t syncing correctly.

To resolve the problem, you need to remove and add the shared mailbox again.

Here are the procedures to remove the shared mailbox:

  • Go to your Outlook program.
  • Navigate to File.
  • Click on Account Settings.
  • Press on the Account Settings. outlook-account-settings
  • Select your email address.
  • Click the Change button. outlook-change
  • Select the More Settings option. outlook-more-settings
  • Go to the Advanced tab.
  • Press on the mailbox name you want to remove.
  • Click on the Remove button. outlook-remove
  • Confirm by pressing Yes on the pop-upped dialog box.
  • Press on Apply and then OK.
  • Proceed to Next and Finish the procedure.

Restart your Outlook apps and open them again to add the shared mailbox. You will find the mailbox adding process below.

Here is the process of adding a shared mailbox:

  • Open Outlook.
  • Go to File.
  • Press on the Account Settings.
  • Click on the Account Settings again. outlook-account-settings
  • Choose your email address.
  • Press the Change button. outlook-change
  • Click on the More Settings option. outlook-more-settings
  • Proceed to the Advanced tab.
  • Tap on the Add button. outlook-add
  • Type the name or email address of the mailbox owner and press the Enter button. outlook-add-mailbox
  • Press the Apply and then click on OK. outlook-add-apply
  • Complete the process by pressing the Next and then Finish button.

The owner has to permit you to add the mailbox to your Outlook account if it isn’t granted before.

7. Contact Support

I strongly believe the above solutions have already solved your problem. However, if the issue still appears, contact Microsoft Support for further assistance.
