Hi,

Just recently, I experienced issue somewhat similar to https://solidcp.com/forum/question/error-changing-mailbox-plan/

Creating new mailbox with whatever mailbox plan works flawlessly, but issue occur when updating mailbox to whatever mailbox plan.

As far as I knew there were no changes on Exchange other than upgrade CU 12 about 2 weeks ago.

Here's error in panel:

System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Error executing 'SET_MAILBOXPLAN_RETENTIONPOLICY_ARCHIVING' task on 'test2@101site.tk' EXCHANGE ---> System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> The request failed.
