Connecting Multiple Portals to the Same Microsoft 365 Account

Sometimes, administrators need to connect multiple Avanan tenants to the same Microsoft 365 account.

This might be needed to apply strict categorization of users, where administrators of one tenant do not read emails, files, and messages of users in other tenants.

Use Case

Large global organization with different branch offices managed by different administrators.
MSPs hosting multiple small customers on the MSP's Microsoft 365 account.

Limitations

If you activated the Office 365 Mail SaaS application in the past not following the procedure below, you cannot connect additional tenants to it.
- To connect multiple Avanan tenants to the same Microsoft 365 account, you must disconnect the existing Office 365 Mail SaaS application from the tenant and connect it again. See Deactivating Office 365 Mail and Connecting Multiple Avanan Tenants.
By default, Avanan does not support connecting tenants from different regions (see Accessing the Avanan Administrator Portal) to the same Microsoft 365 account. If you need this option to be enabled, contact Avanan Support.
Each tenant must be restricted to a specific group of users (user group). These user groups must be mutually exclusive and no user can be a member of two such groups.
Currently, Microsoft Teams can be enabled only for one tenant when connecting multiple Avanan tenants to the same Microsoft 365 account.
Single Phishing Reporting Mailbox - By default, a dedicated phishing reporting mailbox can ingest phishing reports for only one Avanan tenant (see Automatic Ingestion of End User Reports ). If you want a single dedicated phishing reporting mailbox to ingest reports from all the tenants connected to your Microsoft 365 account, contact Avanan Support.
