Offboarding mailboxes fails with “PropTagToPropertyDefinitionConversionException.”
Hybrid M365 setup, just recently upgraded the on-prem server from Exchange 2019 to Exchange SE. After doing so, migrations from Exchange Online back to Exchange On-prem fail at 10% with the error “PropTagToPropertyDefinitionConversionException.” I opened a case with M365 exchange support, and after some time, they came back to tell me that the Exchange Online portion of the process is not at fault, and that I have to engage the on-premise support team (this seems a little nuts to me, as its all connected and all supported, but I've been in this business for 30 years now, and it's not the first time I've seen buck-passing), and/or ask this community for help. Hence, this post. That error appears exactly two places on the internet, as far as I can tell: a blog (in German) from an Exchange expert doing cross-tenant migrations, and a page at https://west.jcteams.info/bhit11/docs/EX1232513.html that seems to describe my exact issue. Neither had useful suggestions - mostly, they say this: Set-MoveRequest -Identity "<UserPrincipalName>" -SkipMoving FolderRestrictions Resume-MoveRequest -Identity "<UserPrincipalName>" That didn't actually work, but when I tried the same parameters with Set-MigrationBatch, they worked as long as I ignored the message "The SkipMoving parameter is deprecated. Use the MoveOptions parameter instead. If you have any scripts that use the SkipMoving parameter, update them to use the MoveOptions parameter." So what was a simple process is now a more cumbersome workaround. Does anyone have an idea on how to troubleshoot "PropTagToPropertyDefinitionConversionException?"
O365 Email Migration to Another Tenant while Deferring Migration of Sharepoint files
Hi, This is the context: ChildCompany has O365 and it has an Azure AD in hybrid mode synchronizing to a on-prem AD server. They have an internal domain ChildCompany.com, and an external domain ChildCompany.com where they also receive and send email using O365. ParentCompany is going absorb the ChildCompany some time in next year, and I was asked about the integration options. According to this https://download.microsoft.com/download/b/a/1/ba19dfe7-96e2-4983-8783-4dcff9cebe7b/microsoft-365-tenant-to-tenant-migration.pdf I could do a phased migration, where the end state is that they decomm their onprem AD and that they only use our ParentCompany systems. The business requirement is to start their integration with Email, and then in later phases do the Sharepoint integration as that requires way more analysis on their data sources, as they also have wikis and many other on prem legacy stuff. They are less than 50 users, so I can use Quest migration tools for the email part, but I wonder what needs to happen in what order. This is what I have in mind: Migrate their current O365 into our ParentCompany Office 365 subscription, so that they can continue logging in into their domain joined windows machines using childCompany.co, so they start using ParentCompany.com email addresses, but the problem then is how can they continue using their sharepoint and onedrive resources associated with the Azure and local domain at ChildCompany.com? This is more or less what I have in mind, for the intermediate step, the cutover: Child Company ParentCompany --------------------- ---------------- On-Prem | MS Cloud: | MS Cloud: ---------------|----------------------|-------------- Local AD (ADFS)| Azure Subscription | Azure Sub | Azure AD | Azure AD |--------------------- |--------------------- | O365 Sub -> | O365 Sub | Exchange mailboxes-> | Exchange mailboxes | Sharepoint? -> | ??? | -------------------- |--------------------- I wonder how could it be possible to defer the sharepoint and onedrive migration, so that the child company users can still work on their sharepoint files using their normal auth methods, while disabling childcompany.com as MX so they start using ParentCompany.com mailboxes.Is that even possible? Would make more sense to try to migrate everything at once? That is way more work, but I'm weighting my options.
