Outlook Error - "Due to the size of this email, we've turned off Editor temporarily."

I recently updated my signature block and came across and issue I want to share. 

 I use Microsoft Outlook for my job and transitioned to using the online version instead of the actual program. When I updated my signature block with new icons, all seemed to be ok when I sent a test email right after.

 Later, when I went to create a new email, I noticed all my icons were missing and shown instead as follows

 as well as an error message at the top of the screen stating: "Due to the size of this email, we've turned off Editor temporarily." 

 At first I thought, maybe I need to go into the actual program and update it that way. Once opened, I noticed the old signature block was still there. I updated it there too, closed out and reopened the web version also in hopes everything would sync up. Went to create a new email, and once again, it was still messed up. 

The more odd thing is when I created a new email using the actual program, I did NOT get this error message and all icons were showing fine. I refuse to go back to that version, I just don't like it as much; my personal opinion. 

Come to find out, the message is appearing because the icons were too large for the signature block. A co-worker had originally sent me the new signature block update and I just copied and pasted into my signature. Apparently what was sent to me, the icons were too large in resolution. 

So at first I tried changing the resolution of one of the icons and that seemed to work but consisted of extra steps I did not want to have to do for each one.

 What did I do to fix it? 

So instead, I clicked on the icon from within my coworkers email, right clicked on the icon from within the window that opened and selected 'copy image' then went and pasted it individually into the signature, rather than all together as I originally had done. 

 I did this for each one and low and behold, it is working now. I have tried creating a new email now multiple times and each time it is fine and working as it should. 

I wish I was smarter to know exactly how this worked to be able to explain it better. Unfortunately I am a bit confused since I ended up not having to do any resizing for it to work.

If anyone can explain how this worked, that would be so helpful. 

Hope this helps someone out there. 

ENJOY!!
