RunDll32 Outlook Mail - Windows Host Process Error (SOLVED)

Hello All,

Recently I had a problem with one of my users laptops the laptop model was a Dell M3800 I believe. The problem related to Office 2013.

The issue was - When you create a new mailbox it crashes and gives your an error message or similar to "RunDLL32 WINDOWS HOST PROCESS ERROR".

After hours of trying to solve this issue, rebuilding the laptop, updating, fiddling with windows settings, running SFC /Scannow, etc, etc. I solved the issue! so i thought id share.... 

  1. Open Microsoft Word 2013
  2. Go to FIle, Options, Advanced
  3. Scroll down to "display"
  4. Check the box "Disable Hardware Graphics Acceleration

The problem arises when you have a dedicated graphics card on your computer. This option disables the use of the dedicated card and uses the integrated one instead (I have zero idea why office needs to use a graphics card for its applications since its 2d and runs the same without it).

This issue caused me pain! hopefully I can help others too as I hadn't seen any solutions to the problem like this one.

Rupert

Wracking my brain over this issue for a week now with a client experiencing the exact same problem: Windows 8.1, Control Panel..Mail, Profiles....Add Profile, Enter in name, e-mail and password for your Office 365 profile and it crashes in RunDll32.

Tried everything from running a full battery of updates all the way to removal and reinstallation of Office 2013 to no avail.

THIS FIXED IT!

Crazy---why would hardware graphics acceleration have any effect on whether an e-mail account can be added?  But nonetheless, disabling it was absolutely the solution to this sticky issue.

I'm glad i could help! I don't often write forum posts because most answers are online already but when I spent a week on this mind numbing problem and found no fixes to it I had to write it.

The reason it wasn't working for me (I believe) was either a faulty or incompatible graphics card (It was a dedicated NVIDIA card), and since by default office applications choose to use a dedicated card over an integrated one (even though it would never need a dedicated one to run) means that it can have issues. I also found that it might be a problem with some software the GPU was installing onto my machine. 

Anyway, please direct people to this post when you can!

Cheers

Thanks, this did the trick for me too. Spent many hours trying to solve this error and I was just about to log a support ticket with Office 365 when I saw your posting. I got it working now!

Amazing!

I was trying to set up Outlook 2010 on Win XP in an Asus laptop with only internal graphics card to connect to Exchange 2013 and this resolved the issue somehow. Outlook opened normally and all folders syncing.

Thanks!

Brilliant example of how a completely irrelevant setting can affect severe connection/crash issue.

Firstly, thanks a lot dear Rupert :)

I faced this seemingly irrelevant issue configuring an email account on Outlook 2013 on an HP Envy 15 with dedicated NVIDIA GeForce graphics card with Windows 8.1 Pro being installed on it.

At the first place not I didn't even bother to Google "Rundll32" but I thought doing so is only time wasting. So I tried removing that account on our domain and changed the computer name and then again put the computer on our domain which didn't help at all.

Thanks again dear Rupert.
