Outlook 365 Signature Editor with image blurry on retina display once sent

Question

Hi,

I am using Office 365 on Windows 10 and created a signaure with company logo image. I have followed the following steps but it did not work the image is still blury.

• Click on Insert Picture icon
• Select company logo (2x) - 268 x 56
• Right click on the image.
• Click on Size and reduce height and width to 50%

I have checked files saved in "AppData\Roaming\Microsoft\Signatures" and under "Test Image_files" folder i can see 2 png files created. The following html file was added (part code). I did try to change image002.png to 001.png (268x56) but no luck.

</v:shapetype><v:shape id="_x0000_i1026" type="#_x0000_t75" style='width:100.5pt;

height:21pt'>

<v:imagedata src="Test%20Image_files/image001.png" o:title="BCG Logo@2x"/>

</v:shape><![endif]--><![if !vml]><img width=134 height=28

src="Test%20Image_files/image002.png" v:shapes="_x0000_i1026"><![endif]></p>

Any advise will be appreciated.?

Hi Brvaland,

It seems the size of your image is quite small. If possible, would you mind finding a larger one? Since the resolution scale of the image would affect the sharpness. You can see the example below, it's 16% 4000 x 2400 (left) and 100% 500 x 334 (right).

Besides, I tested in Monthly Channel version 1812 build 11126.20196. For your reference, see Office update history.

Hi Marvin

Thanks for your quick reply.

I did try on outlook monthly channel version 1811 (Build 110290.20108) and it does not work.

The image added to signature is 1000 x 290px and reduce it down to 10% but once email is sent on receipient side user gets low resolution image - 107 x 31 px (attached developer tool snapshot)

I would except image to be original size 1000 x 290 and image resized with width / height attribute specified (107 x 31). This will fix resolution issue of retina display screens.

I am happy share signature html and files if you want to have a look.

Thanks

Hi Marvin,

Sorry the issue is not fixed, it does not work on high resolution display (retina).

Thanks
