When logging in to a customers Exchange Server 2013 environment recently, a pop up caught my eye, indicating the following errror:
An expired certificate as such obviously isn’t such a weird event. However, when zooming into the error, the server that the error referred to was an old, already decommissioned, Exchange Server!
The following locations were checked, to no avail:
- ADSI Edit
- Certificate store on all Exchange Servers
googling searching the web with Bing, I found a solution on the web.
Get-Mailbox -Arbitration | Search-Mailbox -DeleteContent
Keep in mind, to run the command, specific permissions are required. A management role needs to be created with Mailbox Import Export assigned role. Assigning the Discovery Management role is not enough!
