Hybrid deployment for Microsoft Exchange is the norm for very large environments for a number of reasons. With a material portion of your messaging residing in the cloud and managed by Microsoft, knowing when and why declines in service quality occur can be a challenge. Our Microsoft Exchange monitoring tool can help you fill the visibility gap.
Hybrid environments are hard to manage because they involve multiple hybrid services such as ADFS, Azure AD, Exchange Edge server and, sometimes, mailbox servers. Some subsidiaries are on-premises while the group is online in the cloud. Security and compliance are also issues. Of course, all the other online services need to communicate and integrate perfectly with Office 365.
