We have a four nodes Windows 2025 Hyper-v cluster with only one virtual switch of 2 NICS On each node we get this warning repeatedly V-Switch operation IOCTL_SWITCH_GET_INFO_EX (2241648) took too long to complete. Operation Type: IOCTL. Execution time 0 ms. Queued time 0 ms. Expected execution time less than 0 ms. SwitchName: CF06EC90-20EB-460D-9A88-6820BFCCB14D.

We have two standalone Windows 2025 Hyper-v Servers. They have been configured with a network team for Management, one for VM traffic and one for replica traffic. We have configured both hosts with self-signed certificate to configure HTTPS replica. The two hosts FQDN are host1.company.com host2.company.com and those names are resolved in the DNS with the management Network IP. To have the replica going through the "replica team" we created on each host's host file two entry like host1.repl.company.com host2.repl.company.com pointing to the replica network IP. The self-signed certificate of each host contains both fqdn ( xxx.company.com, xxx.repl.company.com ) Problem is that when activating a replica for a VM if we chose xxx.repl.company.com as replication partner the process fails with the error that the hosts cannot be contacted, if we use the fqdn company.com it works. To test connectivity we also set the hosts file using the replica network IP for the company.com FQDN and it works. So it's like it doesn't like the FQDN repl.company.,com Any Idea on what the issue might be ? thanksRe: Common user attributes synchronized
VasilMichev I was trying to do it, I found that KB as well, with this command New-DynamicDistributionGroup -Name “TEST” -RecipientFilter "(RecipientTypeDetails -eq 'UserMailbox') -and ( l -eq 'Text')" to filter by "city" which should correspond to "l" but I got this error Write-ErrorMessage : Cannot process argument transformation on parameter 'RecipientFilter'. Cannot convert value "(RecipientTypeDetails -eq 'UserMailbox') -and ( l -eq 'Text')" to type "System.String". Error: ""l" is not a recognized78Views0likes2CommentsCommon user attributes synchronized
We have Entra id Connect configured to synchronize with Office 365 tenant for Exchange Hybrid environment. We noticed that in exchange online when trying to create a Dynamic distribution group based on user properties only a limited subset is available. Even common attributes as "city" are missing. Is it something related to the Entra ID "default" configuration that does not synchronize such attributes or is something due to exchange online ? thanksSolved122Views0likes4CommentsDDG fields
We have Dynamic Distribution groups on On-prem which are using user's attribute as, an example, City and we should create the same DDG on Exchange Online. However we when creating the DDG from the Exchange Online Portal such attributes are not present. The only attributes shown are State/provice Company Department Custom1-custom15 Is there a way to have all the user's attributes available for creating DDG ?61Views0likes1CommentRe: OU list incomplete in AAD connect
LainRobertson Thanks for the input. I checked the missing OU's security settings and it has the inheritance enabled as the OU that I see. Checking the permissions they looked the same. The AdSync service is running as NT SERVICE\ADSync EDIT: even if apparently they have the same security settings applied "inherited" checking with "effective access" in the advanced tab for the "user" NETWORK SERVICE there's actually a difference that I couldn't understand coming from.19Views0likes1CommentOU list incomplete in AAD connect
We're facing a strange issue while configuring EntraID Connect. At the point of selecting the OU we want to synchronize the list we see in the EntraID application is not complete in respect of what we see in ADUC. We miss an OU at first level, which by the way is ont of the OU we need to sync. Any idea ?Solved214Views0likes4CommentsRe: Local domain mailbox migration error
Dan_Snape that's correct, I know that it's the default policy managing the domain.local address and that I can remove it to solve the issue. My point is that in all other situations where I had the same configuration, I did not have such issue while migrating mailboxes to O365 in hybrid environment and cannot understand it52Views1like0CommentsRe: O365 hybrid connector to onprem failing TLS

AnnTaeYoun I know that, but I'm talking about the "AD internal domain" which is by default added to all exchange users created. Each user has his primary SMTP address as user @ domain.com which is the public domain and an alias pointing to the AD domain domain.local. We made several migration and never happened that the internal AD domain was rejected during the migration133Views2likes0CommentsLocal domain mailbox migration error
I ran into an issue while migrating from on-premise to O365. On-premise AD domain is “domain.local” so users have their mailboxes smtp address as follows: primary smtp mailto:email address removed for privacy reasons ( public domain ) aliases smtp proxy: mailto:user@domain.local We setup the hybrid environment and started the mailbox migration but they’re failing with the error that domain.local is not an accepted domain in O365. this is the first time it occurred to us since we made a lot of migration so far What can it be ? obviously is not possible to add domain.local as accepted domain in o365235Views3likes8CommentsOn-prem shared mailbox access in hybrid Environment
Migrating user's mailboxes from exchange 2016 on-prem to exchange Online in Hybrid configuration. What is the best approach regarding the shared-mailbox present on-prem ? Users migrated to exchange online lost access to the shared mailbox, outlook removed the shared mailbox from profile, until the shared mailbox is not migrated as well. Is there a way to have the migrated users still able to access the on-prem shared mailbox ? thanks SCSolved157Views0likes1Comment
