Hello all.

I am experiencing an issue with a critical user who is currently in an ongoing litigation from 2013.   Currently his O365 sent folder only is showing emails from 2015 on.   He needs to be able to locate emails prior to 2015.   When the original migration was done from their old exchange environment to O365 by default we took everything that was in the onprem exchange and sucked it into O365.   However a year later we are being told there was more mail then what is currently listed.   I found a link on Microsofts retention policy

https://docs.microsoft.com/en-us/exchange/security-and-compliance/messaging-records-management/default-retention-policy

This is a very confusing article.   Because of O365 default retention policy that we are unable to get mail before 2015.   Has anyone run across this?  This is critical that they are able to retrieve sent messages prior.   If he logs into portal.office.com the mail only goes back to 2015 so policy somehow kicked in I think when the migration was done and only did 5 years worth.   But I have a feeling when the migration took place there was more than 5 years, so I am hoping perhaps email is sitting somewhere in MS cloud and can be retrieved prior to 2015.   As always appreciate the help.

P.S. I am reading that after the retention policy date is exceeded email goes into an archive.   Is this retrievable?

I have two Exchange servers that are failing to backup using Veeam. The error is:

Exchange servers (both of them with the same error:

Failed to prepare guest for hot backup. Error: RPC function call failed. Function name: ISsnapshot in progress) Target machine x.x.x.x. RPC error, The RPC server is unavailable. Code 1722. Error: RPC function call failed. Function name: (ISSnapshotinprogress). Target machine x.x.x.x. RPC error. The ROC server is unavaialble. Code 1722


I ran vssadmin list writers, none of the writers are in an error state.



Would this issue be related to firewall ports not being accessible on the Exchange server? And if so which ones should I create an exception for?

I configured the mail forwarding hook inside the office 365 admin console to flow to a different mailbox. How can I setup this user when getting the forwarded mail comes over that it can go right into a separate folder?

I am assuming it needs a separate folder and a rule for the targets inbox correct?

I've posted a similar question that's a work in progress that's related to a DC backup failure.

Can someone please recommend some troubleshooting steps to rectify this error?

We are running MS Exchange 2010 in a DAG environment. We are running our Exchange environment with update rollup 13.
Exchange Update Rollup 29 for Exchange Server 2010 SP3 was accidentally downloaded and installed to one of the Exchange servers in the DAG. The problem caused by rollup 29 being installed is users that have their mailboxes that server are  not able to access OWA.

When I try to uninstall Rollup 29, I get this Error message:
"Setup wizard for update rollup 13 for Exchange Server 2010 Service Pack 3 (kb2141339) ended prematurely."

I other words, when attempting to uninstalling Rollup 29 which I don't need, setup tries to uninstall rollup 13 which I do need.

We successfully completed a cut-over migration from Exchange 2010 to O365.  We utilized the Azure AD Sync Tool to populate all the users and sync all the mail.  The migration actually completed the first week of January.  I've left the exchange server up and running just in case something went wrong this whole time.  

On February 3rd, I disabled the Azure AD sync with O365, so now all mailboxes Sync Status shows the "Cloud" instead of "Sync with AD".  I left the Azure AD Connect Tool installed on one of our DC, and will remove it in the near future.

On February 6th, I powered down our Exchange 2010 server and then powered it back up yesterday, February 13th.  I just wanted to make sure any mail related services were not pointing to the Exchange 2010 server.  One week with the server off-line should be sufficient for this need.

Now I want to start removing the Exchange 2010 completely.  All O365 mailbox management will be done in the O365 console. and I simply do not want to have any exchange services within our local network.  I want to properly remove the exchange server so that all the Exchange AD attributes are properly removed in case we decide to install another on-prem exchange server in the future.  

I first want to know if I need to remove all the mailboxes before removing mailbox databases, etc.  I am using the following article to assist me remove Exchange:

I'm currently attempting to migrate three mailboxes from one Exchange 2013 CU19 Mailbox to another.  

On one hand, in the status window on the migration batch UI shows that 'Data migrated' keeps growing.  On the other hand, when looking at the status detail, I see this:

Transient error MailboxOfflineException has occurred. The system will retry (6/60).

Over and Over again.  

If I check using GetRequestStatistics, it shows under status detail the following pattern, also repetitively:  InitialSeeding, MDBOffline, NetworkFailure

I've already migrated over 60 mailboxes without an issue; this error seems to occur only for the last two Im working on.  I've already tried a mailbox repair, stopping the health service, and also mounting and dismounting the db.  Any other ideas?

switched to office 365 and now I keep getting prompted for a password to connect to my exchange server.
I tried going to credential manager and deleting the entry, and have verified that autodiscover can be resolved by nslookup and is working properly.

I'm finally getting around to getting rid of my 2010 after moving everything to 2016. The error is "This server is responsible for generating an offline address book. Removal is not permitted"  It seems since I have multiple GALs, Address lists, Address book policies and OABs that its a challenge. I thought I could just delete them all and re-create on the new server but it won't let me delete. Each one says it's being used by the other, this and that, etc. It's a vicious circle.  I still need all the address list and OABs for multi-tenant seperation. What do I need to do?

I have a user who is retiring work but wants to export some folders containing emails in her desktop outlook to a new personal web based outlook.com address. This address is not linked to the exchange version. Can this be done with .pst files? Or can these only be imported to desktop Outlook?  If so is there any other way to achieve this?

Thanks in advance.

is there a specific security role in office365 which would allow our risk team to run message trace requests and also have complete unrestricted to the various audit logs, such as the unified audit log. e.g. that mentioned in here:

https://docs.microsoft.com/en-us/microsoft-365/compliance/search-the-audit-log-in-security-and-compliance

it would be also useful to identify the current auditing settings, e.g. what is and what is not being captured, so identifying

I have a client with a small office.  Their ability to access files on their local fileserver workstation (Windows 10 Pro) is essential.
They use in-office network and VPN client software when in the field.

Internally, there is a simple peer-to-peer network that works well for them.
However, the owner got tied up with Azure AD somehow and now there's a bit of a mess.  It looks like there is single sign-on involved although I really don't know what for and I don't think they do either.

I hadn't paid much attention to their email as it has always worked.  They're on a company domain named Microsoft Exchange account.

I'm not an expert on Microsoft products (Azure, Office, OneDrive, Exchange, etc.) and fear that "cleaning things up" might be more trouble than it's worth.

I'd be very happy to get the boss off AzureAD and to have a single local user to log on to his own workstation.
I just don't want to break:
- email: this must be easy as all of the other users are local users.
- OneDrive

The owner's PC has two logons:
One is an AzureAD\username account.
One is a local account that I set up for user-matching with their fileserver.  The AzureAD\username account doesn't seem likely for doing that.

Today, he did a Windows Update on his PC and lost access to the fileserver in the process.
I have it fixed now but can't say that I did anything at all to make that happen.

In one sense, I'd like to just leave things alone.
On the other hand, I'd like to get …

I have a client with the domain1.com emails being taken care of by Exchange Online.

We are in the process of bringing another domain (domain2.com)  into the Office 365 system.

I have only verfified domain2.com in Office 365 and not done anything else. We do not want to change the mx record yet as mail is still being handled by an external mail service.

Now when a user in domain1.com sends and email to domain2.com the emai gets bounced back.

How do I configure Exchange Online so that mail sent to domain2.com contniues to go to the external mail service.
