Teams Call Queue Cross-Tenant Migration

  Handling Call Queues and Auto Attendant during Cross-Tenant Migration   Note: Call queues can’t be externally chatted with. This is an important information and is the main problem you will have to deal with. Nevertheless, there is a feature, where a call is assigned to a Teams Channel. This allows at least the functionality of Guest User Access. Steps for handling Call Queues: Identify all Call Queues and Groups/ Channel(Teams) Identify all User assigned to Call Queues Identify Users assigned to multiple Call Queues Identify the purpose of the each Call Queue Identify Call Queue used internal, external (phone), internal and external, channel used For all Call Queues used internally, discuss and consider changing them to a Channel based Call queue and build a solution for revers Guest Access.

This address has the following format: x500:/o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOxxxxxx)/cn=Recipients/cn=234xxxx This address is now found in the Exchange proxyAddresses in On-Premises as well as in Entra ID.

How to hide users from GAL if they are AD Connect synchronized

Image
How to hide and un-hide users from Global Address List (GAL) in Exchange Online if they are AD Connect synchronized Hiding User from GAL isn't possible if those are synchronized form On-Premises Active Directory. The local AD is the leading system for all important attributes, like SMTP, UPN and hiding from GAL. Especially during a cross-tenant migration, you do not want to see not migrated user in the GAL. Those User aren't actively working until their cut-over day. Since the Exchange Online attribute  msExchHideFromAddressList s is an AD on-premises parameter, we have two possible ways hiding user in BME from GAL.   Modify the AD Connect for your teant with a custom rule, by using a extensionAttribute to set the HidefromGAL. In this rule, for users which have an entry in the extensionAttribute, hiding / un-hiding will be controlled by AD Connect This is the best option for Cross-Tenant Migration, if you run 2 or more AD Connect system We direct modify the AD hide at

User Adoption Process Cross Tenant Migration

  Cross Tenant User Adoption Process   Change & Adoption is the most critical task in any tenant-2-tenant migration. Not only users who are migrated are impacted heavily by the migration. Users in the target tenant too. Especially in the target tenant they will experience constant changes. New users and groups are appearing, but not “life”, not actively working in the tenant. Further, new services related content will sequentially appear, like SPO sites, Teams Channel, Yammer or others. Since data is flying in slowly, there must be a communication and identification in place, that user are enabled identifying data source in migration. Same applies, for user in the source environment. Content/ data migrated will be in read-only. Content could become unavailable due to accomplished migration to the target. All depends on the migration process, procedures and planning. This needs to be communicated to all users in proper manner. Talking about external users, there is even a m

Working on an end-2-end overview, technical considerations and understandable working template, this Migration book, it was work consolidated during the last 1 ½ years.
