Rules to Better Office 365

Using Active Directory Federation Services (ADFS) lets you use one account to log into multiple systems, through Single Sign-On (SSO).

Microsoft Entra ID - formerly Azure Active Directory, Password Hash Synchronization (PHS) is one of the methods you can use if you want to have your identities synced to the cloud, alongside Pass-through Authentication (PTA) and Federation with AD FS. If you have a hybrid identity in place with Entra ID, chances are you are already synchronizing password hashes to the cloud with Microsoft Entra Connect formerly Azure AD Connect.

The Dynamics 365 app for Microsoft Teams lets you share records with colleagues without leaving the app. Instead of sharing non-descriptive URLs, use the integration to provide more context.

The default message size limit in Exchange Online is 25MB. Even though email attachments are not the best way to share a large file, sometimes it is the only option - and these days, 25MB is quite small. This default limit should be increased; it is easy to do so from the Exchange admin center or Exchange Management Shell.

Microsoft provides a collaboration tool called Microsoft 365 email groups on the cloud, which allows users to send emails to a group of people using a single email address. These groups can be created and managed from any location with an internet connection and can include both internal and external recipients. Microsoft 365 email groups on the cloud offer a wide range of collaboration features, making them an effective tool for streamlining communication and improving productivity.

In Microsoft 365, user mailboxes are limited to 50GB or 100GB, depending on the licence you have. For users with lots of emails, you need a solution to keep mailboxes under the limit, without losing data or access to emails.

There are 3 ways to "archive" emails in Outlook/Exchange, however there's only one true archive option that should be used - Archive Mailboxes (also called Online Archive, or In-Place Archiving).
