You can issue a command to disable the ESE forced reboot, the cause is well explained by Don's answer. I did it latelly for a custumer with a single server with esx, as the IO was overkilling the Exchange. (its still killing it, as it take age to simply open a management console in example, but atleast it dont reboot..) Add-GlobalMonitoringOverride ...

Your storage system is failing or too slow to keep up. If IO has been stalled for too long, Exchange thinks that storage is dead and kills Wininit to force hard reset. See https://technet.microsoft.com/en-us/library/ff625233.aspx and scroll to the end. It's the same for 2013 and 2016. In some cases, the entire storage stack may be affected by the hang, ...

Horde Although I don't know if your also using Plesk/Odin, which I am, I ran in the same problem. After some search it seems Horde Webmail has some built-in functionality for that and if that is not the case for you, you can install addons for that. For example, when you login in to Horde Webmail go to Agenda and edit the agenda you want to have on ...

You cannot install Exchange and Office Web Apps on the same server. Putting Exchange on to a DC isn't a good idea. The best option here is to use VM tech with two physical boxes: Host 1: VM1: DC, VM2: Exchange Host 2: VM1: DC, VM2: Office Web Apps server. Remember with Windows 2012 R2 standard, you can install two VMs on a single physical machine. ...

I wouldn't put anything on the DC other than AD DS, DNS, DHCP and possibly Print Server. OWA is a component of Exchange. It's not a separate Role. SharePoint and Skype could potentially be installed on the same server. I don't understand this statement: This is also presuming multi-partitioned hard-drives as required by the installation. What installation ...

The 3 digit error codes come from the original SMTP specification RFC 821. The dot separated error codes are RFC 3463 compliant which was drafted because those SMTP error codes were deemed insufficient: There is a need for a standard mechanism for the reporting of mail system errors richer than the limited set offered by SMTP and the system ...

Have you check if these aren't just non-delivery notices sent in responses from spam that was sent to invalid internal email addresses ?

We had the same issues when moving from Windows 7 to Windows 10. I followed the given solutions in this Microsoft article: microsoft support - exchange connection. After this everything worked fine again. But take a look at AutoDiscovery as well. Even if you think it might work make sure it really does. A lot of problems with exchange have their root ...

I had this problem once when the Forward Lookup Zones on the Exchange server didn't have the correct DNS entries for the public domain, only the local domain. The Outlook client continued to error out and change the Proxy server connection on me. If your autoconfigure isn't correctly configured, you may also find that the authentication doesn't work properly ...

All that is set is the attribute MSExchDelegateListLink, there is no enforcing of using the same Outlook version. As an admin you may want to force users to use the same Outlook version by configuring 'Outlook client blocking' - https://technet.microsoft.com/en-us/library/dd335207%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396

Every Exchange mailbox is always associated with an Active Directory user object; when you create a room or resource mailbox from Exchange, a corresponding (disabled) AD user account is created. The attributes for the mailbox are stored in that user account.

The only reliable way is to move the mailboxes to Exchange 2013 for everyone who needs to use ECP. Anything else will quickly become an admin nightmare.

If you want to keep track of bouncing, most bounces are sent back to the return path. Bounces contains the name of the email that's being bounced back normally in a NDR Format (Non-delivery Receipt). You can then use tools like ListNanny to process those bounces. Or another option will be to use PHPList as your mailer and let it process the bounces for you ...

You can use Office 365 Message Encryption. Users have to login with either a Microsoft account or a one-time PIN code to view the message. You can disable the PIN code option to enhance the security. It won't know any recipient details like SSN though.

Outlook will auto download images for addresses in the Safe Senders list. You can push out a Safe Senders list to all clients via Group Policy and/or Registry settings. https://support.microsoft.com/en-us/kb/2252421

I haven't personally used the Microsoft Azure Rights Management service, but it should fit into your requirements to protect the data just nicely. IT won't ask for a PIN or code, but it I believe that it's a better solution for ease of use. https://channel9.msdn.com/Series/Information-Protection/Azure-RMS-user-experience ...

The Exchange Sender ID agent will take action when the SPF status = FAIL. The SPF status for your test email = NONE. There is no SPF record so the Sender ID agent can't take any action based on the SPF record, because it doesn't exist.

The Exchange 2010 Management Tools are only supported on Windows 7 or Vista. You may get lucky and have it work on Windows 10 but there is no support for this setup. You can install the Exchange 2010 management tools on the following Windows operating systems: Windows 7 Windows Vista with Service Pack 2 (SP2) Windows Server 2008 SP2 Windows Server ...

Offline defrags? Is it 2005? Create a new database and move the mailboxes. Zero risk, zero downtime - unlike an offline defrag. If you really don't have the space, then another option would be to stand up a temporary Exchange server, move those mailboxes you want to delete to that temporary server and delete them from there. That should give the white ...

List out mailboxes and remove Get-Mailbox -Database <database> You can do something fast like Get-Mailbox -Database DB02 >> C:\MailboxesToDelete.txt and then $users=Get-Content C:\MailboxesToDelete.txt foreach ($user in $users) { Try{ #Print to screen user mailbox to delete Write-Host "User: $($User)" #Mark Mailbox for ...

Deleting the mailboxes isn't going to reduce the size of the mailbox database file. You need to perform an offline defrag of the mailbox database to shrink the file. You might be better off moving all mailboxes to a new mailbox database and removing/deleting the original mailbox database, if you have enough disk space to do so.

If you're asking specifically about Hyper-V Replica then I think it might make sense to balance the load rather than have one host mostly idle. Set up a DC on each host, and then set up Exchange on one and SharePoint on the other. After this, set up your VM replication and you should be set. As already mentioned, you don't need to replicate your domain ...
