Over the past few months, we’ve enhanced compatibility across platforms and further stabilized the product. Additionally, Microsoft is phasing out "legacy" authentication for Exchange Mailboxes, which may affect Microsoft 365 users. If you’re a Microsoft 365 user, please refer to the following article to update your installation accordingly!

Lastly, while this may not apply immediately, it’s essential to always update your Microsoft Exchange environment with the latest manifest.xml file, if you're updating. This recommendation also applies to Microsoft 365 users.
