Signatures - right mouse button

Question

Signatures - right mouse button

Luca Samiolo 40

Hi,

we have PCs with Outlook 2021: when we right-click in the body of a new email, instead of showing the drop-down menu with copy, paste, etc., a window appears with the names of the saved signatures. Why does this happen?

Thanks.

Regards.

Hi Luca Samiolo,

Welcome to Microsoft Q&A Forum!

Have a good day and I hope you're doing well!

Thank you for sharing the details. I completely understand how confusing this must be, especially since the right-click behavior in Outlook usually shows the standard editing menu, not the list of signatures.

I’ve recreated this scenario in a test environment and noticed that it can sometimes happen when the right-click is performed too close to the existing signature block in the message body. Outlook appears to interpret that action as interacting with the signature area itself rather than the editable text space.

Before we go further, could you please try this quick double-check:

Temporarily disable your default signature and test on a blank email:

1. Go to File > Options > Mail > Signatures...

2. Under Choose default signature, set New messages to (none).

3. Open a new email. It should now be completely blank, without any signature inserted.

4. Right-click anywhere in that blank message body.

If the normal right-click menu (Copy, Paste, etc.) now appears, the issue is likely related to Outlook recognizing the signature region as non-editable.

If the problem still happens even in this blank email, please continue with the following steps to rule out other possible causes:

Start Outlook in Safe Mode

This helps check if an add-in might be interfering.

1. Completely close Outlook.

2. Press Windows + R. type: outlook.exe /safe and press Enter.

3. Create a new email and right-click in the message body again.

If the normal menu reappears, one of your add-ins is likely the cause.

You can disable them via File > Options > Add-ins.

Repair the Office application

If Safe Mode doesn’t help, try restoring the Outlook components:

1. Open Control Panel > Programs and Features.

2. Select Microsoft Office > Change.

3. Choose Quick Repair first.

If the issue remains, run Online Repair for a deeper fix.

Create a new Outlook profile

If the issue persists even in Safe Mode and after repair, the Outlook profile may be corrupted.

1. Close Outlook.

2. Go to Control Panel > Mail > Show Profiles > Add… Tess

3. Create a new one (for example, TestProfile) and add a single email account.

4. Open Outlook with this profile and check if the issue is gone.

If right-clicking now works correctly, your previous profile was corrupted. You can safely switch to the new one.

Hi,

thanks for the information. Without the signature, I can see the classic menu (copy...paste) with the right mouse button. I think the problem is the signature: since it's structured like a table, I suspect it might cause problems with the right mouse button. I honestly don't know how to set up the classic right-click menu in an embedded table; can you help me? If you'd like, I can share the signature structure (removing personal references).

Thank you.

Best regards,

Hi Luca Samiolo,

Thanks again for confirming that, and great observation. When composing a new email, Outlook automatically provides one or two blank lines at the top of the message body. That’s the intended space for starting your text.

Could you please try this quick test:

Open a new email.

Press Enter once or twice so your typing area moves further away from the signature block.

Then right‑click in that upper text area (one or two lines above the signature) and check if the normal context menu appears.

You can also compare two cases to verify the behavior more clearly:

(1) Move the cursor and right‑click above the signature (in the text area).

(2) Move the cursor and right‑click below the signature (empty space after it).

Try not to right‑click on the same horizontal line as the signature, because Outlook may interpret that action as an attempt to interact with the signature itself rather than the editable message body.

This helps confirm whether Outlook is distinguishing correctly between the body area and the embedded signature table.

Additionally, to better understand your setup, could you please share a screenshot of the signature structure (via File > Options > Mail > Signatures… > Edit)? Kindly blur or remove all personal and company details, keeping only the layout visible. For example, how the logo and text areas are arranged.

With that visual reference, I’ll be able to recreate your signature in my test environment and gain deeper insights for the next troubleshooting step.

Thanks again for your patience and cooperation!

Hi,

I can't upload the signature completely because it's made up of multiple files and I can't use zipped files.

Thank you.

Best regards,

Hi Luca Samiolo,

Thank you for following up and for your thorough testing so far. I really appreciate your effort and patience.

Based on your previous check, could you please confirm whether the issue happens as soon as you insert the signature, and then the right‑click menu shows the signature list regardless of where you click in the message body? If that’s the case, it’s quite possible that the signature’s structure is somehow spilling over (overflowing) into the text area. This can happen even when the signature looks perfectly sized, but its embedded HTML layout extends invisibly beyond its visible boundaries.

You can try the following adjustments to verify:

Simplify or resize the signature slightly in the Signatures editor.

If your signature includes animated logos, hyperlinks, or complex formatting, try removing or simplifying them temporarily.

Experiment with repositioning where the signature is inserted (for example, ensuring a clear blank line between the signature and the message body).

Please check carefully whether any elements in the signature (images, tables, or links) might be pushing content outside the main body or causing layout overflow.

If, after reviewing and adjusting the signature, the issue still persists and it’s unclear what exactly causes the behavior, feel free to let me know. I can point you to the right process for submitting a ticket to ensure the technical team can assist further.

Once again, I truly appreciate the time and effort you’ve invested. You’ve done excellent troubleshooting so far, and we’re getting very close to isolating the cause.
