Outlook/Office 365 loads wrong display name on To: field.

AWHolmes This worked for about 3 minutes, then reverted to displaying the wrong name.  *#%#@?!

This Fix worked for us, however it does erase any favorites you have set up in Outlook.

I think I found the solution!

 

The issue with Outlook displaying the incorrect name is a failure of the Offline Global Address Book to properly update with the Display Name settings on Office 365 Website.

 

Here is the solution from start to finish:

 

Step 1) Login to Office 365 website as a Global Administrator

Step 2) In the "Admin Center" select "Users"

Step 3) Change the Display Name and Aliases.

Step 4) Log out of Website

Step 5) Open Outlook Program

Step 6) Go to File-> Info -> Accounting Settings (drop-down)-> Account Settings

Step 7) Double click on account with incorrect display name

Step 8) Uncheck box "Use Cached Exchange Mode to download email to an Outlook data file"

Step 9) Hit Next, then Finish

Step 10) Restart Outlook

 

You can go back and select the box again if you want.  Hope this works for you guys. Here is a Microsoft article that I found once I knew what to look for: https://support.microsoft.com/en-us/help/2429946/how-to-troubleshoot-the-outlook-offline-address-book-in-an-office-365

AWHolmes this worked for me....thanks

This fix does not work. I've only seen this once so far with many email setups, but cached or not cached outlook always shows the wrong from name for only some addresses.
