Exchange - In-Place Archive

[skell]

Consider the following scenario

 

- On-prem Exchange 2013 CU13 hybrid with O365

- Enable archiving in ECP and point it to the cloud based offering.

- User gets HostedProvisioned status and the archive is accessable via Outlook.

- The archive appears in OWA, but when its clicked the message "Your archive appears to be unavailable. Please try again later." appears.

- Hybrid Config wizard gives the following warning

 

HCW8064 - The HCW has completed, but was not able to perform the OAuth portion of your Hybrid configuration. If you need features that rely on OAuth, you can try running the HCW again or manually configure OAuth using these manual steps.

 

- Manually configuring OAuth and rerunning the HCW makes no difference.

 

Microsoft seem to think we need to update to CU16 but I'm pretty sure that won't help.

 

Anyone come across this?

For those of those interested, installing CU16 fixed this issue.

 

I would assume it was because we were more than 2 updates behind.
