Hello,
Our company has two entities that share the same Dynamics 365 CRM instance. Let's call Entity 1 (Main) and Entity 2 (Other). Our main email is associated with Entity 1 and four of us have Entity 2 emails.
The scenario is as follows:
Entity 1 (Main)
1. For the most part emails are tracked, both incoming and sent (we had to update a special setting with XRMToolBox to track the sent emails\
2. The remainder of our issues with tracking, I believe, are attributed to issues with Contacts and Accounts
3. The Dynamics 365 Add-in will launch and operate with no issues with our main email
4. All mailboxes are tested and approved
Entity 2 (Other)
1. Emails will track intermittently for one of our team members, which only has the Entity 2 email
2. The other 3 members emails do NOT track; neither incoming, nor sent
3. The Dynamics 365 Add-in does NOT work for Entity 2 emails
4. We purchased a license for Dynamics 365 CRM for Entity 2 email for one user to no avail
5. Setting up/Approving mailboxes for Entity 2 emails has no effect
