Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Dear Experts

We have been provided to configure email account in CRM system to send email through the SMTP server using  office365 connector ( SMTP Relay ) the provided account is of without the password (hence in CRM system configured without SMTP authentication) , we were able to configure this account in CRM system and able to send mails but the messages are not getting stored in sent items. to achieve this should we have to go for Authenticate CRM application directly with an Office 365 mailbox, and send mail using SMTP client submission please suggest, thanks in advance.

Dear Experts, we have several Exchange 2016 servers (VMs) in Vsphere 6.5 environment, but one SAN storage is running out of space.

How can I check whether if we can delete some space in Exchange Database? Due to company policy, we have to keep disabled mailuser for a year; but in urgent they can be deleted.

But I'm not sure to check the space which was taken by those disabled accounts. Can  you please help? many thanks!

Something strange seems to be happening with my email.
1. I am not receiving some emails which I know were sent to me by certain people (because they confirmed so, and the email address was correct, they had sent to a group of persons, including me, but I only received a 'reply all' email from one of the other recipients
2. I sent an email to a friend on Tuesday night and he didnt receive it.  I checked and it was sent, in fact I received the cc copy.  He checked and it didnt go to spam etc.

My email system is:
- I have set-up Google G Suite to receive my emails and synchronise them with MS Outlook on my PC.  (The email arent showing in GMail or on MS Outlook)

Does anyone know what the problem might be, and/or what steps should be followed to identify the problem?

hmailserver_log.txtI've been sending logs and reports from 3 sites at the rate of 20 per site per day.  It has always worked flawlessly - for years.
Suddenly, the emails don't get through from any of the 3 sites.
This happened for a few days about a year ago and then it fixed itself.  So, I didn't get any insight from that.

Here is the path:
Device or program sends an email. addressed to an outside address, via SMTP / local workstation LAN address where hmailserver is running (as a relay only).
hmailserver forwards the emails to fred@r........k.com at our external ISP mail system.
The ISP mail systems forwards the mail to the addressee at a domain / mail server that I "own".
The domain mail server delivers the mail to a POP account on one of my external workstations.
Like this
email to xyz@abc.com sent to server at [local IP addess]
hmailserver running at [local IP address] forwards mail via me@isp.com.
ISP send mail to xyz@abc.com
I get POP mailfor xyz@abc.com in my office.

I have attached a log from the hmailserver which you my well be able to interpret better than I.

In order to fix the disruption, it would be good to know where it's faiing…..

My brother-in-law has forwarded an email conversation to me that was initiated by a request for the payment of an invoice that did not exist. The spam email appears to have come from his email address and was sent to people in his address book. I was wondering if someone could help me to recognise whether the spam email is a spoof or whether someone or something has managed to hack into the email account. I have no real experience of reading email headers so please be gentle.
Thank you in advance.

I have a user using a web hosting company and their webmail to keep emails on the server and in separate folders.

We're moving him to a different hosting company. we want to move the emails / folders from that server to the new server.

I thought I was cute  - I connected outlook via imap to the old server, waited for it to stop saying sync'ing folders.
the exported as PST.

Changed the mail server  settings and pointed to the new mail server via imap.  Folders were empty and not many of them (in, sent, deleted, drafts).

Then I imported the PST into that account. Outlook shows all the folders, but they arent in the new webmail.

The folders / files in them show in outlook but not in the new server.

What's the right way to get emails on a pop / imap mail server into another server?

I set a new IMAP configuration through Outlook 2013 for one of my clients. He originally had a POP3 setup.

My client stated he was wasting allot of time updating his desktop Outlook after he made changes (read, delete, send, etc.) on his iphone, hence the move to IMAP.  

The transition was not easy! He had massive custom folders (including sub folders) under his inbox containing client emails over the years. He is basically keeping a history via his outlook. I ran into a ton of problems attempting to restore a PST backup to an OST IMAP account - too long to explain. At a certain point I was moving one folder at a time/counting emails. I finally got to the finish line. All the folders/emails were synced to the online email server.  As I'm about to report the great news, my client tells me he opened a suspicious word document which turned out to contain a virus.

So...I had to buy new drives , and perform a full restore of  recent backed up images. I bring the system back on line, it performs an outlook sync and proceeds to freeze up the on-line email server web account (purchased through a 3rd party vendor). I am now unable to access any folders, or emails either through the web interface (to a 3rd party email server) or through Outlook. I called up the 3rd party, who stated they will refresh their server. I await the results.

In hind sight, I feel like I should have kept those custom folders out of the sync process. At this point, it feels like a total mess.

Hello Experts - I have a question about making an MX record change.  We are using Barracuda's email filtering service and they are asking that our MX records be pointed to the following addresses:

Primary: d35456a.ess.barracudanetworks.com
Backup: d35456b.ess.barracudanetworks.com

Currently both MX1 and MX2 point to individual Barracuda IP addresses.  The records are hosted with Network Solutions.  When I sign in, I navigate to the Advanced DNS section to edit but the form requires a numerical IP address and won't allow me to enter the addresses above.  I feel like I'm missing something here, any ideas?

Haven’t had to deal with this in a while but have a client we handle LAN tasks for. Their current web/ imap / pop mail host lowered mailbox limits to unusable numbers.

They don’t want to go to o365.

I’ve used hostgator reseller account for years but in thinking of moving them there I remember how we have wanted to get away from hostgator for so long. Their service / support works just enough to keep my inertia on moving at bay.

I know HG (and many other hosts) are part of a much larger holding company.

Is there any good hosting company you’d recommend? Or warn about?

This is unbelievable. An email account or two from one of my customers got hacked. As a result they got blacklisted by... actually GoDaddy (that is who their email accounts are with). So all 65 of these email accounts started bouncing when they sent emails. Now the insane part. GoDaddy says that can't tell which email accounts got hacked (that is lie number 1). Then they want us to:

1) Put up a web site simply because according to the agreement they can't use email without having a web page
2) Change all 65 email passwords
3) Find the first, the very first bounce message someone got. Yes, out of 10 locations and 65 emails then need the very first bounce message received.

   #1 is simple, #2 is annoying but how in the world are we supposed to find the very first bounce message out of 65 email addresses? GoDaddy is a bunch of morons. Even their "advanced team" has no clue how to find the very first bounce message but without it they can't turn the email back on. Anyone have any idea on how to find this one, first bounce message?

Morons. Just a bunch of bleeding Morons.....

Hi,  Iam creating workflows in Jira and I want as port of the flow to send an Email to the operation team once any change has been planned. But I want it to use various field and free text boxes to guide the user in creating the email.

So my idea is that when the use hits "ready to implement) a form pops up with various fields pre filled such as requestor name and date / time of change) and other boxes free texdt or drop down. then once thes user fills in the form and clicks submit Jira created the email and send it to a pre defiend email.

Is this possible to create email body on the fly based on a pop up form?

Thank you

I'm try to test that my Exchange 2010 SP3 UP23 is actually offering TLS on incoming SMTP emails. I have a 3rd party cert installed and assigned to the SMTP service. The default receive connector has the correct FQDN (our external MX ) , Authenication is TLS and Permission Group is Anonymous. I test my SMTP using MXtoolbox.com and it says my server does not offer TLS, but in the SMTP receive logs on my server i find the mxtoolbox.com connection and it has 250-StartTLS listed. i have also Telnet to my exchange server and it also does NOT show 250-StartTLS.

what am i missing? why do the server logs say TLS is offered, but the other end doesn't get it?
Exchange is running on WIn Srv 2008R2, fully updated, with TLS 1.0,1.1, and 1.2

I have a client using IMAP in Outlook. Yesterday she wasn't receiving any emails. I looked at the account settings, and they were all correct. I tested the connection, and the test message went through just fine. Then I closed the windows. After a second or two, her emails started coming in. This morning, she again was receiving no emails. I checked the settings again and again tested the connection, then closed the window. Again, after a moment or two she started receiving emails. She never has a problems receiving emails on her phone (also IMAP). It's like every day I have to remind Outlook it can find the server by testing the connection. This is very inconvenient. What can I do?

Hi All
I need some help please.
I have 5 Exchange 2010 SP3 RU 21 servers running on Windows 2008 R2.
On 2 of my servers mail all of a sudden stops flowing to them.
There’s enough free space across all drives.
The servers are virtualized running on top of Hyper-V Server 2012.
Certificates are valid.
Server time is correct.
When I attempt to restart the transport service on the affected server it fails to stop and then you can’t start it again.
Even going via task manager and ended the exe relating to the transport service doesn’t seem to help.
The only thing that restores mail to and from this server is a reboot.
Any ideas?

Dear Experts, we have Exchange server 2016 on Server 2012R2. Can we using Exchange Management Shell to forward emails from a user's mailbox to another's ?

How can we do it? Many thanks!

For example: user1@ABC.com's inbox have some emails from customer@XYZ.com, we got a request to forward all emails from customer@XYZ.com in user1's mailbox to Boss@ABC.com?

Comcast (Xfinity) is recommending that users move to IMAP for email & I am wondering if there are any downsides to this.
My initial concern is that there will be a ton of duplicates in mailbox at the start, or is that not so?
From what I gather, they have a 10 GB mailbox limit - when it gets near full, would I be able to archive mail to a pst (or any other option)?
Would it be best to start with a new profile?
What about getting everything currently in my pst file into the IMAP folder - would I just open pst file & copy into IMAP folders?
What about phones, ipads, etc - how long till all of that synchs up?
About to do this for a neurotic friend & want to be prepared...

Hello,

I have an Exchange 2010 server Version 14.03.0399.000 which I believe puts it at Service Pack 3 rollup 21. I just did the rollup last week. This server has been running for years flawlessly until I ran this last rollup. Now for some reason, about 3 times a day the SMTP protocol just stops answering.

I believe I’ve got it narrowed down to something happening with the Microsoft Exchange Transport service. Before SMTP stops working I can restart this service, but after SMTP stops talking I can’t restart it, it just hangs.

If I perform a reboot on the mail server all is fine again for 6 to 8 hours.

Any help would be great
Thanks

HI Folks,

I wonder are there any experts out there that know how to analyse email header source. One of our clients received a bogus email that appeared to come from one of our staff members email address.. it did not. .. unless his email account was compromised.

I've asked the receive to send me the header of that bad email and they did. I put the message header into a Google Product called "Message Header Analyzer" and the results are attached.

My question: from this is there any way to determine the source of the email? Our domain is trinav.com. So did the come directly from us or is it from another source and just looks like from  @trinav.com

Am I making sense here? Any help would sure be appreciated!

Thanks!
