Hi All, My work as a Cloud Engineer is around M365 and Azure. As a Messaging Expert, i often use DNS to Query for diffrent Records like MX, SPF, DKIM, DMARC etc.
A while ago, i startet to create a Script that checks all these Settings for a specific Domain. The Script has been published to my GitHub Repo. The Script checks diffrent DNS Records about a Domain - mostly about Mailsecurity Settings.
Hi All, Recently i had the following Error Message in Outlook: DE
Mindestens eine Regel kann nicht in Microsoft Exchange hochgeladen werden und wurde deaktiviert. Die Ursache sind möglicherweise nicht unterstützte Parameter oder mangelnder Speicherplatz. EN
One or more rules couldn't be uploaded to Exchange server and have been deactivated. This could be because some of the parameters aren't supported or there's insufficient space to store all your rules.
Let's have a look at the Mailbox and the Rules Quota - it's already set to the Maximum of 256 KB.
Hi All, It's been a while since i activated External Mails in Exchange Online Set-ExternalInOutlook -Enabled $true I have not updated my Office Version since last week.
But when i restarted Outlook today a saw a new "External" Tag in the Message Overview. Seems to be there was a Change on 10. September 2022
On the Message itself - it's still the same Tip
In OWA nothing changed and it looks still the same
Hi All, Now it's finally have come true: Signatures from Outlook for Windows and OWA are shared.
M365 Roadmap Signature cloud settings
https://www.microsoft.com/en-us/microsoft-365/roadmap?filters=&searchterms=signature%20cloud%20settings
Let's check the Signatures on my Outlook for Windows Client
You can have multiple Signatures in Outlook
And they are now available in Exchange Online OWA
Sadly Outlook Mobile does not support it. Or not yet - don't know. But that would be much appreciated if signatures would be consistent across Clients.
