Migrate Office 365 Groups to another tenant
How can I migrate an Office 365 group, including conversations and calendar, to a new tenant? I found how to migrate individuals using pst files. I found how to migrate from on premises to Office 365 using PowerShell. But nothing about Office 365 to Office 365 migration.Enterprise Vault Archive Data to O365
Hi Team, Can anyone please recommended tool (Microsoft tool/3rd Party) to migrate archive data from Enterprise Vault to O365. And do we have any data limit to migrate data to O365 per day? Just wondering what would be the timelines we consider to migrate per TB/GB data generally? Is it possible to perform EV migration without any tool (power shell scripts etc.? Any inputs will be appreciated. Regards,
Questions on Office 365 Tenants integration
Hi Community, One of our customer has the below environment: Forest A AD Citrix thin clients are installed. Office 365 enabled with Teams licenses (Tenant A) Forest B AD ADFS installed. SSO is enabled. Laptops are provided by vendor and those accounts are hosted in this AD. Office 365 enabled for Exchange mailboxes. (Tenant B) The fact is that the end-users would be using the Citrix Virtual Desktop environment in a full-screen mode. So while Forest B / Tenant B does provide workplace services (like a mailbox) the end-users would not access those directly from their desktop session. Requirement: As a Forest B user, the user should be able to log on to their laptop using Forest B’s AD credentials. (As they’ve SSO enabled they can access Tenant B mailboxes without entering the credentials again) Then the user would be able to log on to the Citrix session using Forest A credentials. User would be able to use Teams with Forest A / Tenant A credentials Then the user would be able to run an outlook fat client logging in using Forest B / Tenant B credentials. Question Teams and Outlook clients from different O365 tenants will create some issues and wanted to find out if such a scenario was supported? Any pointers would be of great help.ADDS trusted forests.domains A. OnPrem EX2013 B.Office 365 into new ADDS and New 0365 Tenant?
Greetings. We have two company's (each with their own forest and single domain) that have operated in a trusted ADDS forest configuration. Each forest contains their own respective mail system. One has on-premise Exchange 2013. The other ADDS forest has O365 and uses Azure AD Connect to sync on-premise ADDS users to o365. These mail systems are utilizing Galsync (enow) to support cross forest GAL's. We are not (yet) using o365 SharePoint, one drive, or other 0365 services other than email. *We will later in the new named entity. We are now going to merge these two environments (ADDS forest(s) / domain(s)) into a new named ADDS entity (forest and domain) - and new o365 tenant. This new named entity will utilize many of the o365 offerings. I have migrated/merged trusted forests, and Exchange on-premise 2010/2013 systems together via ADMT and mailbox moves. This looks to be a bit more challenging. Has anyone performed a similar migration/merge? Would they be willing to share how they did it? Any insight, links, or thoughts are very much appreciated. I found something similar in a forum on reddit -https://www.reddit.com/r/Office365/comments/93f4oq/cross_forest_office_365_migration/ Thanks in advance,
Office 365 Usercredentials are cached
We migrated our data from one tenant to another and a lot of the local user profiles still caches the old tenant data. We found that out because they had a lot of problems with the Teams client in connection with Outlook. Sent out Teams meeting invitations but weren't able to join the meetings... And we also figured out that if we are using this command: dsregcmd /status and the "Work Account 1" is still using the old Tenant (Tenant name, Tenant ID). So the user has to disconnect here manually. But is there a way to do it via Powershell? Or is there any other way to do it remotely for all users? Thanks in advance
Cutover migration with already setup Azure AD and SSO
Hi All, We are looking at doing a cutover migration with our current Exchange 2010 DAG setup to exchange online. We have about 112 users to move so going with the cutover. We're going that way also to remove the ned of having an onsite exchange presents. Only thing that's I've been reading about is that you need to disable DirSync to perform the cutover migration. My question(s) are 1. Will disabling DirSync (which will move all users into the deleted users) stop SSO access to our over products we use day in and day out. 2. Does having an already synced Azure AD impact on the migration, IE will it duplicate users/mailboxes 3. Does having no exchange presences onsite with DirSync enabled (After migration) cause issues? we have no plan on moving back to onsite. We do plan on keeping users onsite and in azure with the Sync Thanks a bunch, I cant find any documentation that covers our specific scenario
Why is RetentionHoldEnabled set to true during hybrid migration?
I noticed that my retention policies weren't being applied after migrating from Exchange 2010 to Office 365. I found this article indicating RetentionHoldEnabled is set to true during the migration and it needs to be disabled for your retention policies to function. What is the reason for this? Is there any issue with disabling this on all of the migrated mailboxes? https://support.microsoft.com/en-us/help/3194755/retention-policy-no-longer-works-after-a-mailbox-is-moved-from-the-onUsers Office 365 Outlook Crashing - Hyper-V with a VM RDS Server running on Server 2019 RDS
We have a brand new Dell R7515 with a new AMD EPYC Processer. The OS is Windows Server 2019 Hyper-V with a VM RDS Server running on Server 2019 Standard. We decided to go with a shared license Office Pro Plus installed on the RDS Server. Each user is licensed in O365 with an MS 365 Apps for Enterprise License. There was nothing special configured about each user's Outlook except Cached Mode was enabled since employees are using O365 Groups. Shortly after cutting over users, we found that some employees were experiencing crashes when sending emails outbound. The crashes appear to be completely random, unrepeatable and occur only a few times a day. The only consistent theme was 98% of the cases; the employee was hitting send right before the crash.

Cutover migration of external domain without AD sync
Hey all was wondering if anyone is familiar with exchange migrations where you don't want to pull over the AD accounts. We acquired a company and want to migrate there exchange to our office 365 tennant but not sync there AD. We want to exchange server mainly for historical data and will convert them to shared mailboxes when imported, but I am unable to find an answer on weather this is possible or not.
