With Exchange 2019, something has changed in the search index, the search index for the Outlook and OWA search is no longer separate from the mailbox database in the file system, but has been moved to the database as part of the mailbox. Resetting the search index by deleting the search index files in the file system works with Exchange ... Read more
I have just uploaded a new version of the Exchange Certificate Assistant. The old version still uses the Let's Encrypt protocol ACMEv1, which is no longer supported by Let's Encrypt. The new version 3 of the Certificate Assistant now uses the PowerShell module Posh-ACME to automatically request certificates for Exchange Server via Let's Encrypt. Posh-ACME is ACMEv2 ... Read more

This problem only occurred when the mail routing was switched to the Exchange 2016 ... Read more

Exchange 2019 was already announced last year, but this year there is no new Exchange version, so Exchange is probably only a topic in a few sessions this year. Perhaps ... Read more
