Hi @Arin W
Welcome to our forum!
Does the issue occur recently on Outlook Desktop Client? Do you have any specific operation before the issue occurred?
What is the version of your Outlook? It is recommended that you please check the Outlook client version (File>Office Account>Product Information) and try to upgrade to the latest version to see if the problem is resolved.
In addition, here are some steps you may want to take:
- Check Email Signature:
- Ensure that your email signature does not contain any blank images.
- Go to File>Options>Mail>Under Compose Messages, Stationery and Fonts>E-mail Signatures and review your signature settings.
- Check for Add-ins:
- Sometimes, add-ins can cause unexpected behavior in Outlook. Disable all add-ins and see if the issue persists.
- Go to File>Options>Add-ins>Click on Manage COM Add-ins and uncheck all add-ins, then click OK.
- Restart Outlook and check if the blank GIF still appears.
- Create a New Outlook Profile:
Hope it helps!
