We will soon be adding several additional file extensions to the BlockedFileTypes property of existing OwaMailboxPolicy objects. This change will prevent Outlook on the web users from downloading attachments that have those file extensions. Why are we making this change? We’re always evaluating ways to improve security for our customers, and so we took the time to audit the existing blocked file list and update it to better reflect the file types we see as risks today. How does this affect me?...

Microsoft posted the article, "Improving Security - Together" where they explain that they will be turning off Basic Authentication in Exchange Online for EWS, Exchange ActiveSync (EAS), POP, IMAP and Remote PowerShell on October 13, 2020.

Sincerely, Ricardo, Duncan, Sunder and David on behalf of the Outlook team" After I posted the article, "Storing email signatures in the Exchange mailbox" on this blog, this UserVoic...

As part of continued improvements to the Exchange Online service we are releasing an improvement to the User object management experience. Today, when you create or modify user’s properties via Exchange Admin Center (EAC), Exchange Online PowerShell or other API, the change replicates to Azure Active Directory (AAD) through a sync mechanism which can take some time to complete. Simply put, you might not see the result of your change in AAD for a while. This “back-sync” mechanism (as you ma...
