Much to our surprise, this blog is covering the availability of three new Office 365 browser themes. We’re only doing this so that we can avoid including it in the Office 365 for IT Pros eBook. We know this will upset some people, especially fans of the unicorn theme, but we really have to draw the line somewhere when deciding what should be in the book.
Exchange Online supports inactive mailboxes as a way to keep mailbox data online after Office 365 accounts are removed. Inactive mailboxes are available as long as a hold exists on them. You can update mailbox properties to exclude all or some org-wide holds. If you exclude holds from a mailbox, you run the risk that Exchange will permanently remove the mailbox. If that’s what you want, all is well, but if it’s not, then you might not be so happy.
The CISA report titled “Microsoft Office 365 Security Observations” makes five recommendations to improve security of an Office 365 tenant. The recommendations are valid, but competent administrators won’t take long to implement them. In fact, the worst thing is that consultants brought in to help organizations didn’t seem to have much expertise in securing Office 365.
On May 7, Microsoft eventually fixed a truncation bug that affected group events (creation, add member, etc.) ingested into the Office 365 audit log. The fix took far too long coming and the overall response is certainly not Microsoft’s finest hour. Audit events, after all, are pretty important in compliance scenarios and it’s not good when those events are incomplete.
One of the great things about Teams is the way that it orchestrates Office 365 resources like SharePoint Online sites. The downside is that a tenant’s valuable SharePoint storage quota might be absorbed by a profusion of Teams. To offset the problem, you can apply lower limits to sites belonging to Teams and the best approach is to use PowerShell for the job.
