Delist IP Address

This is Exchnage 2016 deployment. For some reason out IP has been in banned sending IP lists.

We've tried the O365 Anti-Spam IP Delist Portal.  We first tried this around 5 hours ago.  At which point we were told that in about 30 minutes the IP address would be delisted.  However,  the problem continued,  so we've tried again (and again etc).  Now when we try to delist we get a message saying "The request to delist IP address XXX has been denied and we have escalated your request to Microsoft support.  However, there's no information on turnaround time or how to contact the correct Support team.

This issue is huge for us - we are unable to contact numerous clients and candidates until it's resolved.

We aren't currently Office 365 customers (though we are considering this as a solution). we are right now using Microsoft Exchnage 2016. Is there any other way we can expedite unblocking our IP address.

432 4.3.2 STOREDRV.Storage; mailbox server mapi session limit exceeded; STOREDRV.Deliver.Exception:TooManyObjectsOpenedException.MapiExceptionSessionLimit;Failed

Wondering if anyone can point me in the correct direction for dealing with a really annoying issue. The last few weeks we have had mail flowing really well and now the following issue has popped up yet again. I have no idea why after everything has been working well. No changes have been implemented anywhere so I'm stumped as to why this has started happening.

The problem is on some of the queues with the following message:

432 4.3.2 STOREDRV.Storage; mailbox server mapi session limit exceeded; STOREDRV.Deliver.Exception:TooManyObjectsOpenedException.MapiExceptionSessionLimit;Failed

Google has not been my friend when looking at this and what happens is that the relevant queues this hits builds and builds and then it re-tries, deals with a shit load of mail and then it starts to build again.

Hi,

Need some help on one specific request that my management team has. For all the sales department they want to set a rule in Outlook or from Server side, where if any email they receive and if it is unread for more than 15mins then it should be forwarded to his manager and if he also keeps the mail unread then it should be forwarded to his manager (up to 2 levels). Is this functionality can be achieved without any third party <g class="gr_ gr_781 gr-alert gr_gramm gr_run_anim Style multiReplace" data-gr-id="781" id="781">utility ?</g>

If it requires third party utility then what tool I should be looking.

Thanks,

List Parent Distribution Groups that Nested Distribution Groups Might be Members Of

Hi,

We have a series of typical regular universal distribution groups. We also have a large number of dynamic distribution groups. The dynamic distribution groups have been placed / nested in the universal distribution groups

We need to be able to determine which static groups a dynamic group is a member of

We're not looking to list the members of a group, or to recursively list members of a group and the members of a group nested within each group. Instead, we want to be able to determine, for example, which universal distribution groups the dynamic distribution group "MyDynGroup" belongs to

We have tried:

$groups = Get-DistributionGroup
$groups | where-object { ( Get-DistributionGroupMember $_ | where-object { $_.Name -eq “MyDynGroup”}) }

we have also tried commands along the line of:

Get-DistributionGroup |  Get-DistributionGroupMember | where { $_.Name -eq "MyDynGroup"} | select name

No joy unfortunately

Any help would be greatly appreciated

Thanks

Exchange Server 2013 and ms-Exch-SMTP-Accept-Authoritative-Domain-Sender

January 8, 2015, 11:18 am

Hello, Team!

I think I’ve found a serious issue in last CU releases. This is the case:

1 Multirole server Exchange 2013 SP1 (and older) , one creceive connector from internet to this server, no edge, nothing.

I care about preventing spoofing my company’s email addresses, and remove remove the ms-Exch-SMTP-Accept-Authoritative-Domain-Sender transport permission from anonymous senders.

To do this, we usually simple run powershell command

Remove-ADPermission <ReceiveConnector Name> –user “NT AUTHORITY\Anonymous Logon” –ExtendedRights ms-Exch-SMTP-Accept-Authoritative-Domain-Sender

This command works on Exchange SP1, the client (telnet session, f.e.) which try spoof address of company will be refused. (see screenshot below)

But in Exchange 2013 CU5, CU6 and even CU7 release this revoke permissions DOESN’T WORKS without any errors, softly. I've try Powershell and ADSI but unsuccessfully.

Then we take off permission on connector above, we keep 3 default permissions:

Accept-any-sender

Accept-Routing-Headers

Submit-Message to Server

It is wonderful works only on server SP1, but not on servers with older versions, which have right settings.

The saddest thing is I have information about Office 365 this behavior reproduced too. And I also think what in your lab you could take 15 minutes and play this simply thing....

I found only that information on connector side is diffenent on SP1 and CU5,6,7.

This is normal connection on SP1, when somebody try spoofed address. We can see a 250 AUTH Response on server side, and server refuse fake connection, all right.

And on CU5 and newest versions we doesnt see this code. Maybe auth mechanism miss something?

Any suggestions? On MS connect site a didn't found exchange bugs topic :)

For the past few weeks we have experienced e-mail problems with Hotmail domain senders.

Only the Hotmail accounts are not coming in, all other domains work just fine.  We can also send anywhere as well.

I have not made any changes to our Exchange2013 server or spam services, everthing is working as it was before.

Please help, I have the SMTP logs and the emails generated from Hotmail addresses never even left the Microsoft servers.
Almost as if my domain is listed as internal for Microsoft.

Thank you!

Force TLS 1.2 on a send connector

Hello,

I am configuring Exchange with a third party cloud email smart host for message hygiene. In reading the report on the traffic between the Exchange 2013 servers and and the smart host in the cloud, I noticed that the connection says it is using TLS 1.0. I was wondering if I can force the connection to use TLS 1.2, but without using the registry hacks to disable TLS 1.0 and TLS 1.1 all together. The remote smart host supports and is configured for TLS 1.2. The Exchange servers are running CU13, so they should be OK as TLS 1.2 support was introduced in CU8. Thanks!

Internet Send connector

My question is about how Exchange 2013 manages the Servers added to a internet send connector.

Does it work as a Load Balancer, or only active, passive mode? failover kind of deal....(using the secondary only if the primary stops responding)

for example if i have an application sending 2000 emails per hour, is Exchange smart enough to use both available servers to do the Sending, or does it only send through one (default).

If mails starts queuing up would it start using both?

Regards,

MS

Good afternoon. There is Exchange 2013 + Outlook 2010,2016. The user creates the certificate for enciphering of letters (on the basis of a template from corporate CA), adjusts it in Outlook. In case of receipt of the encoded letter the user can't open it, gives an error message that the certificate isn't found.

Transport Rule

Is it possible to create a transport rule that will reject an email to a certain internal address (our helpdesk app) that has any other address in the to: or cc: fields? My users will submit a helpdesk request via email and either cc multiple people or include them in the to: field. They continuously hit reply all and when our helpdesk email address is included we end up getting multiple replies back to a ticket after everyone replies all with their 2 cents worth. I created a rule that works great when the helpdesk address is in the CC filed. I need it to work basically if there is any other address in the email aside from helpdesk

Block ALL attachments

I am looking at trying to create a transport rule to block ANY and ALL attachments in the Exchange 2013 environment.

Test 1 was creating a rule using "Any attachment is greater than or equal to..." 0kb and found that this will block any email that is sent whether it actually has an attachment or not.

Test 2 was creating a rule using "Any attachment's file name matches...".  While using RegEx, for example [a-z0-9], I have been able to block emails with attachments.  The issue with this is if the body of the email has a large amount of information the email will be blocked even if the email does not contain any attachments.

Anyone out there have any experience with blocking all attachments in their environment?

ex2013 - accepted domains - deleted but still relaying

Hi guys.

one domain has been moved to Office 365. This domain was on exchange 2013 premises before.

We have deleted that domain on accepted domains list on on premises exchange 2013.

We kept users mailbox onpremises until we conclude everything Works fine.

We have removed mail allias (the domain that was moved to Office 365) on this users mailbox.

Internal mail flow still Works internally.

Mx records on internal and external dns points to Office 365.

If we sent an email from internal exchange user to this domain it still gets delivered internally.

What else to check?
