I'm running a migration for a small customer (about 400 mailboxes). half of the mailboxes are migrated just a couple of random mailboxes failed with this error. Has anyone faced/worked around this issue? I've tried following with no success: -Tried after a server restart -Tried creating a new batch ---- Error ---------------------------------------------------------------- Data migrated: 46.29 MB (48,542,751 bytes) Migration rate: Error: SourceMailboxAlreadyBeingMovedPermanentException: Couldn't switch the mailbox into Sync Source mode. This could be because of one of the following reasons: Another administrator is currently moving the mailbox. The mailbox is locked. The Microsoft Exchange Mailbox Replication service (MRS) doesn't have the correct permissions. Network errors are preventing MRS from cleanly closing its session with the Mailbox server. If this is the case, MRS may continue to encounter this error for up to 2 hours - this duration is controlled by the TCP KeepAlive settings on the Mailbox server. Wait for the mailbox to be released before attempting to move this mailbox again. --> -->249Views0likes2CommentsSMTP Issue - Exchange 2019
Hi All, I have an hybrid exchange environment (365 + 2019), and the onprem server is used for smtp relay only. An internal app uses this relay and send email as "email address removed for privacy reasons", and all works well except by an specific message-subject. This application can send all the emails with any subject, but if the subject is "Purchace Order to be approved" the relay fails. Checking logs, I could see that when the message has this mentioned subject then the field "sender-address" is always empty (return-path is ok). And, of course, SPF/DKIM fails and message is quarantined. All other message subjects contain the address in "sender-address". This could be an issue with my application or something related to smtp config?

We have moved all users off on-prem EX16 8 weeks ago. 3rd party did full migration to MS365, new external Azure AD, no hybrid mode. EX16 has been in maintenance mode for 3 weeks. Have dismounted databases. I am finding lots of conflicting details about decommissioning this server. It was a single server, no DAG, 50 users. Most instructions are for migration to on-prem higher versions with users still tied to local AD and EXCH. I just want to remove it from the environment and retire hardware. Not finding un-install details specific to this scenario. Anyone have some direction?26Views0likes1CommentHow to count messages sent from a specific mailbox
Good morning everyone! I hope everyone is well. As always, I warn you that I don't speak the language so I can help myself by using an online translator. I hope you can make me understand. If not, I am happy to explain my situation further. Briefly: I need to count the number of messages sent by a specific mailbox. Report how many were sent. I don't know if this is important information, but shipments are made in the majority - or in almost all cases - using a shared box. There is the report in the Admin Center and honestly I'm still getting used to it. I assume there is some delay in generating it in relation to the data obtained. But this is a feeling. What I wanted - and this could be the most complicated thing - is to use some command, which does this reading and brings me this data. I tried to do some reading but in addition to not finding anything very specific, I also didn't really understand how my question would be possible. I have a time problem. I am a resident of a region in Brazil that was hit hard by floods. rains. A true climate catastrophe. And my job is to support the teams that organize all the operations here. Therefore, I apologize if this time I do not ask for something for study and understanding but something more direct. If you can guide me - or show me the way - in a more direct way, I would be very grateful. Thank you in advance for the attention that everyone can give to this issue Have a good day at work everyone HugsSolved764Views0likes3CommentsAutomatic redirection of Exchange ActiveSync On-Pre

Hello everyone, I am having this issue where I can't find any useful answer. We are connecting to Exchange Online with certificate based authentication and it works fine when we run the script manually. Running the script via scheduled task with the same user, we always receive the following error messages. PS>TerminatingError(Get-ConnectionContext): "One or more errors occurred."

Please try again later. PRX5
Office 365 refuses SMTP authentication with error: 451 4.7.0 Temporary server error. Please try again later. PRX5 This is when accessing External Send SMTP AUTH through OAUTH2 authentication. Initial authentication is successful (and is logged as so in Entra ID) but when trying to send send messages through authenticated SMTP, you get the above error. Working with multiple support reps, we looked through login logs and could not find any trace of the error in Entra ID. Support reps all blame the third party application. The issue is connected to a special use case, where a user has both the GLOBAL ADMIN role, as well as certain other admin roles. When you have a certain combination of those roles, for a selected user, OAUTH2 will fail, even though OAUTH2 for (apparently) ALL OTHER SERVICES - work without error! - ONLY SMTP Auth is affected. RESOLUTION: Keeping Global Admin while simply removing excess roles will almost immediately resolve the issue. This bug has been publicly noted as far back as August 2022, perhaps earlier. This needs to be fixed.2.1KViews3likes10CommentsAccess to Exchange Admin Centre blocked using most (but not all) URL links
Suddenly, when I try to use most of the published links to the Exchange Admin Centre, including the links on the Microsoft 365 Admin Centre, my access to the Admin Centre for Exchange is blocked. The messages vary but the most common one is "admin.exchange.microsoft.com closed the connection". All of the links for the other admin centres work just fine for me (Teams, InTune, SharePoint etc.) - it's just the Exchange Admin Centre link that are mostly problematic. Two examples of links that don't work for me: https://admin.exchange.microsoft.com/?landingpage=homepage&form=mac_sidebar https://admin.exchange.microsoft.com/#/homepage The only link I can find that still does work for me: https://admin.cloud.microsoft/exchange#/Solved280Views1like2CommentsDelegating permission to approve Quarantined Mobile Devices in Exchange Online
Hi all, I would appreciate some guidance. Today, we are configured to quarantine any mobile device that attempts to add their mailbox to their device. We have three administrators that can approve these devices. I'd like to delegate this responsibility to the person on our team who stages and deploys mobile devices without giving them full administrator access. Additionally, I am looking to grant access within the GUI, not the ability to run a PowerShell cmdlet. From this post on Reddit, I first attempted this process, but it did not seem to work. In the GUI, a user in the group I created cannot access the Mobile Devices page in the Exchange Admin Center. I then attempted this link to Microsoft documentation, but it doesn't seem to fit exactly. Granted, I don't have much experience with Exchange permissions. Any help, guidance, or direction you could point me in would be greatly appreciated. Thanks Steve196Views0likes4Comments
