Microsoft Exchange refers to an older certificate that no longer exists, ID 12023.
We have one Microsoft Exchange 2013 server. The Windows Application log periodically displays the ID 12023 entry, which states that Microsoft Exchange could not load the certificate with the thumbprint 3E8XXXXXXXXXXXXXXXXXXXXXXXXXXXX from the local computer's personal certificate store. This certificate was deleted because it expired, and a new self-signed Auth certificate was created. Now, when running the Get-AuthConfig | Format-List CurrentCertificateThumbprint, PreviousCertificateThumbprint, NextCertificateThumbprint command, only the current certificate is displayed. The Microsoft Exchange 2013 server is running. The question is, what should I do to remove the ID 12023 entry from the Windows Application log?
Keep user account but provision new empty mailbox
i did ask in another forum but thought i would ask here as it seems impossible... we are hybrid exchange. We have litigation hold and purview retention policies in place. We have a scenario where an existing user is moving to a new role and her existing mailbox needs to be dissociated from her AD account and a new clean mailbox provisioned. The original mailbox needs to stay as inactive and searchable via ediscovery. Is it possible? I have asked AI and its said: Make sure all the holds and retention policies are in place Move the AD account to a non-syncing OU and run a delta sync The mailbox should show as inactive in exchange online Then it tells me to run Set-User <UserUPN> -PermanentlyClearPreviousMailboxInfo but ONLY if the recipient type shows as MailUser or User This is where i am stuck as it is still UserMailbox. It told me to restore the cloud only object which i did. But it still shows as RecipientType = UserMailbox when i check. Its now just a cloud only account, it has no license. The mailbox is inactive but its still a UserMailbox Is what i am trying to do possible? Would now just changing the cloud only account to have a new email address be the only way to retain it and then sync back the on-prem account?
DMARC rejection after Exchange upgrade
I'm having problems with inbound emails getting bounced as Undeliverable due to DMARC rejection. For many years I've had my email come through Fasthosts / Livemail to my own domain (qts.org.uk) with catch-all forwarding set to forward everything to my GMail account. Just recently Fasthosts have upgraded their servers to Exchange and I've started getting DMARC rejections from GMail which start Diagnostic information for administrators: Generating server: exchange2019.livemail.co.uk Total retry attempts: 1 (my gmail email address) t1-hex-xprelay.gem.livemail.co.uk Remote Server returned '550 5.7.26 Message rejected by DMARC policy by gmail.com. Please use your own email address as the sender, instead of (sender's email address). [MSG0009]' Which bounce from Fasthosts / Livemail back to my GMail address. My own domain has SPF, DMARC, and DKIM configured I've done a little digging and it appears to only affect senders from originating domains with DMARC set to reject. So either GMail has coincidentally become much more strict (possible) or Fasthosts are somehow failing to forward emails fully transparently. I have spoken to Fasthosts and logged the issue with them and was not impressed so I hope the experts here can offer a solution I can forward to them.
Modern Auth EWS error 50199 when signing from Crestron Touchpanels
Good Afternoon, All I am having a difficult time nailing down this issue. I have a few Crestron TTS-770s that were, up to last week, working correctly by pulling Calendars data with EWS. They were configured with a service account signed into EWS using 'modern authentication'. This week, these panels have disconnected and report that 'Needs to be authorized' as the EWS status. I have verified that CA is not blocking sign in, the account is excluded from MFA policies, and is correctly licensed for Exchange Access. We do not use Intune for device management. When I attempt to re-register the device, I follow the prompts until I am prompted to close the browser window; The device spins, then fails to connect with the status above. I have attempted this with the service account and my own Admin account with MFA, to the same result. Entra Enterprise Apps Sign-in logs show a 'Successful' entry, then immediately after, a 'Failed' entry with an error '50199'. I had not made changes to any of the URIs before initial failure, and any additional entries or changes do not change the results of the error. Initial URI was configured to 'https://app.noop' (no idea, was configured before I got here, and I hadn't needed to change it), I have attempted combinations of our Tenant URI, ' https://login.microsoftonline.com/common/oauth2/nativeclient', and other 'fixes' I had found while GTS-ing. I additionally have set my 'legacy authentication' and 'legacy applications' CA polices to read-only for troubleshooting. I am working to disable OAuth2ClientProfile on Exchange Online temporarily for troubleshooting. Does anyone have any ideas? Please let me know if any additional information is needed, or if needed to post in another location. Thank You
