Why Cant I Forward An Email In Outlook – Enabling Forwarding Options

by

You press the forward button on an email in Outlook, and the message fails to open. This is a common frustration, and you might be wondering why cant i forward an email in outlook. The issue can stem from several causes, from simple settings to more complex technical glitches.

Dont worry—most problems have straightforward fixes. In this guide, you will learn the exact reasons behind this issue and how to resolve it step by step. We cover Outlook for Windows, Mac, and web versions.

Why Cant I Forward An Email In Outlook

This heading covers the core problem. When the forward button does nothing, or the email opens blank, it is usually due to one of these reasons:

  • Corrupted email item or mailbox
  • Outlook add-ins interfering
  • File attachment size limits
  • Outdated software version
  • Email format or security settings
  • Profile or data file issues

Let us break down each cause and show you how to fix it.

Corrupted Email Item Or Mailbox

Sometimes a single email becomes corrupted. When you try to forward it, Outlook freezes or gives an error. This is more common with emails containing complex formatting or large attachments.

How to check: Try forwarding a different email from the same folder. If that works, the original email is likely damaged.

Fix:

  1. Open the problematic email.
  2. Copy the entire content (Ctrl+A, then Ctrl+C).
  3. Create a new email manually (Ctrl+Shift+M).
  4. Paste the content (Ctrl+V) and send it as a new message.
  5. Delete the original corrupted email.

If the issue persists, the mailbox itself might be corrupted. Run the Inbox Repair Tool (Scanpst.exe) for Outlook data files. This tool is located in your Outlook installation folder.

Outlook Add-Ins Interfering

Add-ins are small programs that extend Outlooks functionality. But some add-ins, especially third-party ones, can block the forward feature. They might conflict with Outlooks code or consume too many resources.

How to check: Start Outlook in safe mode. Hold the Ctrl key while clicking the Outlook icon. If forwarding works in safe mode, an add-in is the culprit.

Fix:

  1. Go to File > Options > Add-ins.
  2. At the bottom, next to Manage, select COM Add-ins and click Go.
  3. Uncheck all add-ins and click OK.
  4. Restart Outlook normally.
  5. Re-enable add-ins one by one to find the offender.

File Attachment Size Limits

Outlook has a default attachment size limit of 20 MB for most accounts. If the email you are trying to forward has attachments that exceed this, the forward function may fail silently.

How to check: Look at the attachment size in the email header. If it is over 20 MB, that is likely the issue.

Fix:

  • Remove large attachments before forwarding.
  • Use a cloud link instead (OneDrive, Google Drive, etc.).
  • Compress files using a zip tool.
  • Check your Exchange server limits if you use a corporate account.

Outdated Software Version

Microsoft releases regular updates to fix bugs and improve performance. An outdated Outlook version can have unresolved issues that block forwarding.

How to check: Go to File > Office Account > Update Options > Update Now. If updates are available, install them.

Fix:

  1. Run Windows Update to ensure all system files are current.
  2. Restart Outlook after updates.
  3. If using Microsoft 365, check the version number against the latest release.

Email Format Or Security Settings

Outlook supports three email formats: HTML, Plain Text, and Rich Text. Sometimes an email in a specific format cannot be forwarded due to security restrictions. For example, emails with digital signatures or encryption may block forwarding.

How to check: Look for a red ribbon icon (digital signature) or a padlock icon (encryption) in the email.

Fix:

  • For signed emails: Remove the signature before forwarding. Right-click the signature area and select Remove Signature.
  • For encrypted emails: You cannot forward them directly. Ask the sender to resend without encryption.
  • Change the email format: Go to File > Options > Mail > Compose messages in this format. Try switching to HTML.

Profile Or Data File Issues

Your Outlook profile stores settings, account info, and data files. If the profile is corrupted, forwarding may fail. Similarly, the PST or OST file (where emails are stored) might be damaged.

How to check: Create a new Outlook profile and test forwarding.

Fix:

  1. Go to Control Panel > Mail > Show Profiles.
  2. Click Add to create a new profile.
  3. Set up your email account again.
  4. Open Outlook with the new profile.
  5. If forwarding works, migrate your data from the old profile.

Outlook Web Access (OWA) Issues

If you use Outlook on the web, forwarding problems can be different. Browser cache, cookies, or extensions might interfere.

How to check: Try a different browser or an incognito window.

Fix:

  • Clear browser cache and cookies.
  • Disable browser extensions temporarily.
  • Check if your organization has disabled forwarding in admin settings.

Antivirus Or Firewall Interference

Some antivirus programs scan Outlook emails in real-time. This can block the forward function if the software misidentifies the action as suspicious.

How to check: Temporarily disable your antivirus or firewall. If forwarding works, the security software is the issue.

Fix:

  • Add Outlook to the antivirus exception list.
  • Disable email scanning in the antivirus settings.
  • Update the antivirus software to the latest version.

Registry Or Group Policy Restrictions

In corporate environments, IT admins can disable forwarding via Group Policy. This is rare but possible. Similarly, registry keys can block the forward button.

How to check: Look for grayed-out forward button or error message like “Forwarding is disabled.”

Fix:

  • Contact your IT department to check policies.
  • If you are an admin, navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options in Registry Editor. Look for DisableForwarding. If it exists, set it to 0.

Email In The Drafts Or Outbox Folder

Sometimes you try to forward an email that is still in your Drafts or Outbox folder. These emails are not fully sent and may not support forwarding.

How to check: Look at the folder name. If it says Drafts or Outbox, the email is incomplete.

Fix:

  • Open the draft email and complete it.
  • Send it first, then forward the sent copy.
  • Delete the draft if you dont need it.

Outlook Running In Compatibility Mode

If you installed Outlook on a newer Windows version but set it to run in compatibility mode for an older version, features like forwarding may break.

How to check: Right-click the Outlook shortcut > Properties > Compatibility tab. See if “Run this program in compatibility mode for” is checked.

Fix:

  • Uncheck the compatibility mode box.
  • Run Outlook as administrator temporarily to test.

Large Number Of Emails In The Folder

If your Sent Items or Inbox folder has thousands of emails, Outlook may slow down. The forward function might time out or fail to load.

How to check: Look at the folder size in the status bar or folder properties.

Fix:

  • Archive old emails to a PST file.
  • Use the Clean Up Tools in Outlook to remove duplicates.
  • Create subfolders to organize emails.

Email With Embedded Images Or Scripts

Emails containing embedded images, scripts, or active content can cause Outlook to block forwarding for security reasons.

How to check: Look for a yellow bar at the top saying “This message contains blocked content.”

Fix:

  • Click the yellow bar and select “Download pictures” or “Enable content.”
  • Copy the email content into a new message as plain text.

Third-Party Software Conflicts

Other email clients, sync tools, or productivity apps can interfere with Outlook. For example, if you have a CRM plugin that integrates with Outlook, it might hijack the forward function.

How to check: Disable all third-party software that interacts with Outlook.

Fix:

  • Uninstall recently added software.
  • Use Task Manager to end non-essential processes.
  • Perform a clean boot of Windows to isolate the conflict.

Outlook Data File (OST) Sync Issues

If you use an Exchange or IMAP account, Outlook syncs emails to an OST file. If the sync is incomplete or corrupted, forwarding may fail.

How to check: Look for sync errors in the Outlook status bar (bottom right).

Fix:

  1. Go to File > Account Settings > Account Settings.
  2. Select your account and click Repair.
  3. Follow the prompts to fix the sync.
  4. If that fails, delete the OST file (Outlook will recreate it).

Outlook Not Responding Or Frozen

Sometimes the forward button appears to do nothing because Outlook is frozen. This is often due to high CPU or memory usage.

How to check: Press Ctrl+Alt+Delete and open Task Manager. Look for Outlook under Processes. If it says “Not responding,” that is the issue.

Fix:

  • Close Outlook via Task Manager (right-click > End Task).
  • Restart Outlook.
  • If it happens often, check for add-ins or large PST files.

Frequently Asked Questions

Why Cant I Forward An Email In Outlook But I Can Reply?

This usually indicates a corrupted email item or a format issue. Reply uses the same email structure, but forward creates a new message. Try copying the content into a new email. If that works, the original email is damaged.

How Do I Enable The Forward Button In Outlook?

If the forward button is grayed out, check Group Policy restrictions (corporate accounts) or registry settings. For personal accounts, ensure you are not in a read-only folder like Junk Email. Also, check if the email is encrypted or signed.

Why Does Outlook Say “Cannot Forward This Message”?

This error often appears for encrypted or rights-managed emails. The sender has restricted forwarding. You cannot bypass this; ask the sender to remove the restriction. Alternatively, take a screenshot or copy the text manually.

Can A Large Attachment Stop Me From Forwarding?

Yes. Outlook limits attachments to 20 MB for most accounts. If the email has attachments over this limit, the forward function may fail. Remove attachments or use a cloud link before forwarding.

Why Cant I Forward An Email In Outlook Web?

For Outlook on the web, browser cache, extensions, or admin settings can block forwarding. Clear your cache, disable extensions, or try a different browser. If you are in a corporate environment, contact IT.

Final Steps To Resolve The Issue

You now have a complete list of causes and fixes. Start with the simplest solutions: restart Outlook, check for updates, and test with a different email. If the problem persists, move to more advanced steps like running the Inbox Repair Tool or creating a new profile.

Remember to backup your Outlook data before making major changes. If you are in a corporate network, involve your IT department for policy-related issues.

Most users find that clearing add-ins or updating Outlook resolves the problem. If none of these work, consider reinstalling Office completely. This is a last resort but often fixes deep-seated issues.
