Reject/bounce message based on non-presence of attachment

February 14, 2019, 12:04 pm

We have a somewhat complex workflow designed for a bid proposal project. 
External senders can send emails with attached bids to a series of mailboxes located on our Exchange 2010 server.
A transport rule then forwards that email to an external O365 address, and rules on that side then upload that attachment to Sharepoint. This mailflow is working as desired.


I am trying to devise a way to bounce any message that does not contain an attachment, and then notify the sender so that they can resubmit properly.


I am not certain if this can/should be done within our cloud email management (Mimecast), Exchange, O365, or some combination of the three - but the logic seems simple enough. Any insight or ideas on how to build this out will be greatly appreciated!

Exchange logs - Proxy Protocol.

we have an exchange 2010 environment.  its being load balanced by an F5 LTM using SNAT.  right now we are only getting the F5 ip address in our logs.  however, the F5 team set up an irule on their side, using the 'Proxy Protocol' and they are inserting the true source IP into the TCP header.  

my exchange question is this.  how do i configure exchange to accept/read this header.  its basically like an x-forwarded-for, except for no http traffic.  here is how the header reads from my tcpdump:

281702019-02-14 13:40:28.63774310.47.x.x10.40.90.40SMTP14387C: PROXY TCP4 10.11.x.x 10.47.x.x 44218 25

Hi there,

During the migration process of moving our mailboxes to office 365, we have inadvertently screwed up our SSL certificates on the exchange 2010 server. 

We have the certificate codes necessary however now all our e-mails on the server have stopped receiving e-mails. 

We need help/guidance on the best way to totally uninstall all certificates on the exchange 2010 server and start again from fresh such that our e-mails start receiving and sending again. 

We have tried all steps on the internet, but to no avail. Everything we do the server says has been 'successful' however still no e-mails....

Please help!

Error - externalemailaddress is mandatory on mailuser - while running Exchange 2010 Setup (Mailbox Role)

We are trying to install a 3rd Exchange server to be used as a Mailbox Role in a DAG configuration. It passes all the neccessary preconfiguration tests, but as it gets to the Installation of the Mailbox role then throws up this error

STEPS.

  1. Server Role Selection - Mailbox Role only
  2. Preparing Setup - Passed
  3. Mailbox Role - Failed

Error: The following error was generated when "$error.Clear();if (($server -eq $null) -and ($RoleDatacenter -ne $true)) { Update-RmsSharedIdentity -ServerName $RoleNetBIOSName}" was run: "ExternalemailAddress is mandatory on MailUser. PropertyName: ExternalEmailAddress".

ExternalEmailAddress is mandatory on MailUser. Property Name: ExternalEmailAddress

Elapsed Time 00:00:03

This is the 3rd server/exchage install all done according to a checklist, have destroyed VM and recreated to be absoutely sure there were no hangovers left from first failed install.

 

  • Server 2008R2 with SP1 (plus all current updates)
  • Exchange 2010 standard with Service Pack 1
  • 8GB RAM
  • 40GB OS Drive
  • 100GB Data Drive
  • Dual Homed IP's 192.168.1.1 (LAN) 10.1.1.1 (Replication)
  • Replication NIC has Microsoft Network disabled as well as File/Print Sharing. Advanced settings are LAN as first binding priority

Any assistance would be appreciated in trying to sort out why the setup brings up this error. I have read in places that it can occur when running a script to move a mailbox (or create one) and you forget to include the homeMDB field, but not sure twhy that is relevant with a normal setup routine from the actual software manufacturer. If I have forgotten anything important to include, please let me know and I'll post the information required.

I have an Exchange 2010 database with about 700 mailboxes. I need to merge a PST calendar file into all those mailboxes. I'd like to script it so I don't need to perform the merge for each mailbox individually. Does anyone have any recommendations or examples of scripts that I could use?

I’m not able to edit membership of My Universal security groups using outlook, when I add/remove members it shows the error

“Changes to the public group membership can’t be saved. You do not have sufficient permission to perform this operation on this object”

I've already assigned the RBAC role “Security Group Creation and Membership” to a security group and the user who is editing the group is the member of this role group. I’ve also tried to assign the role directly to user, but it also did not work.

Exchange 2010, Outlook 2010.

Could someone please suggest me on this.

Shared Mailbox (Online) freezing Outlook - Exchange error event 9877

January 11, 2019, 3:18 am

Hello,

We have a team of 4 people working on a shared mailbox. (By default shared mailboxes are not being cached.)
Sometimes this mailbox becomes unresponsive and freezes Outlook (2016).
Restarting Outlook fixes the issue until they click on the shared mailbox again.

This issue lasts for a good 10 minutes until it goes away by itself.
It can last hours, days or even weeks before it happens again. There doesn't seem to be a set interval for this problem.

What I do notice is that each time event 9877 is logged 5 to 10 minutes before the people report the issue.

Content Indexing function 'CISearch::EcGetRowsetAndAccessor' received an unusual and unexpected error code from MSSearch. 
Mailbox Database: MBX-DB-03 
Error Code: 0x80041606 

The error has occured for all our mailbox databases in the past.

The error has occurred for all our mailbox databases in the past. But only 1 team is currently reporting issues with a shared mailbox. (1 mailbox also had this problem, but this one is no longer being actively used.)

Can the issue be related to the Indexing error?
If yes, can we fix something server side? I would rather not have caching enabled for shared mailboxes as we have had our issues with that in the past.
We are running Exchange Server 2010 Standard SP3 RU22 (Build: 14.03.0411.000).

Thanks.

Outlook 365 clients not synchronizing unless cached mode disabled (Exchange 2010).

Yesterday we setup 5-8 Outlook 365 clients to an Exchange 2010 server (autodiscover).

The users had a mix of IMAP and POP accounts set up. We manually exported to .pst, created new Outlook profiles and imported. However, today we learned that no mail is syncing, unless we go and disable cached mode. Cached mode also runs quite slowly, so definetly not a solution. The Outlook clients status' are "updating inbox" or similar. But no new mail is coming in. The Exchange 2010 server is working for other people in the organization.

Any help would be appreciated.

Certificates | Exchange | F5 Firewall

We are two teams, I manage Exchange & network team manages the F5 firewall device. I wanted to buy the certificate (third party) for my exchange but before that the F5 Firewall admin prepared a csr & purchased a cert for his device for the same common name & autodiscover. F5 Admin was pretty sure that if i give my cert it will not work in his device.

Now, I was thinking to buy first & then export and give it to F5 Admin. Anyways, Can I Export the certificate from F5 device and Use the certificate for exchange.

If yes, then how do i go about it. Simply import it and assign services because if i prepare csr then the cert will not be valid as it was not obtained using that csr.

If no, then does it means that I have to obtain a new cert. Do all organizations spend twice the money to buy the cert for same names but different devices.

Thanks

Outlook Calendar invites from 1 domain displaying as plain text

Hello,

Exchange 2010

Version 14.03.0339.000

We are receiving meeting invites from a particular domain as plain text. All other meeting invites are coming in properly formatted.

This specific domain is able to successfully send a properly formatted meeting invite to other exchange organizations. So not too sure what I should be looking at. Could it be that the IronPort does something to the email headers and strips the format and converts it to plain text? Or could it be the Exchange server? Does anyone know what I should be looking at to get the meetings received as an calendar invite and not as txt?

Thank you

I can no longer gain access to our Exchange Management Console 2010 on our 2008 R2 Server.  Has worked fine for the first two weeks.

EMC 2010 Initialization failed. 

The following error occured while searching for the on-premises Exchange server:  No Exchange servers are available in any Active Directory sites.  You can't connect to remote Powershell on a computer that only has the Management Tools role installed.  It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true -CurrentVersion 'Version 14.1 (Build 218.15)".

Any suggestions are appreciated, I cannot find anything regarding this error.

Hi,

I have a bit of a strange issue.

I'm running on Exchange sp3. I've notices that once I hit logoff on owa it would actually kick out other sites. From what I have tested so far it only happens in IE 11. I didn't have this issue when I was running SP2.

Help will be greatly appreciated.
