Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Problems installing OneNote and Skype; Outlook Mail does not Sync in RS4

Since installing RS4 on two HoloLens devices, I've been unable to install OneNote or Skype. The error message reads 'Something unexpected happened' and error: Code 0x803FB005

Also, Outlook Mail adds my Outlook.com account but is unable to sync e-mail showing 'Nothing has arrived yet' and a bang error (!) over the sync symbol that indicates a Sync Error. No other details and I've tried adding my account a few times.

Other MS apps work, such as PowerPoint, OneDrive, Word and Edge.

Has anyone else encountered these problems or do I have an issue with my account settings?



  • Same problem here. Installation of Skype or OneNote generates the unexpected error.

  • I'm unable to open Feedback Hub on the HoloLens to log this issue. Is there any word from MS?

  • Skype works ok for me but OneNote doesn't sync

  • Same here has anyone got a work around to get skype working with rs4? Or has microsoft contacted anyone with regards to how long the fix will take?
