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, I am wondering if we can monitor the usage of users' mailboxes in Exchange 2016 Server (Win2012R2), just like we usually monitor servers, network devices,...; so that we can have proper actions when someone nearly reach his/her quota.

Do you know any tool or procedures to do that? Many thanks in advance

Dear Experts, can we create a distribution group which contains email accounts from different domains (than the server's domain)? If so, how can we configure it?

Example: Exchange 2016 server for domain abc.com

Can we create a distribution group that includes?
- user1@abc.com
- user2@gmail.com
- user3@xyz.co.uk

Dear Experts, can we delete the log files in %ExchangeInstallationPath%\Mailbox\DB ?

We observed and saw that they increases everyday. If we cannot delete them, how can we reduce their size?

Anyone know the SMTP authentication for San.RR.com?   I'm also not well versed in Apple Mail client so I may be doing something wrong.  I referenced below but I don't see SMTP authentication... My options are External, Kerberos, NTLM, MD5, and Password.  Also, do I need need a IMAP path prefix ?

Dear Team, we are suffering the slow problem of Email Exchange 2016: Send from Exchange server is OK, but receive is slow; which ever have or does not have attachments.

We have Avast installed in Exchange server, everything in default mode, not sure which Exchange part should be added to AV's exclusion.

Is there any other way for tuning or increasing the speed (except increase the bandwitdth, we are in Leased line link: 30 Mb/s International + 50 Mb/s Domestic)?

Many thanks as always!

Can one add a hyperlink to fields that when clicked not only creates an email but can fill in the other email fields like CC, Subject, and Body?

I have done this in excel, but not sure if the hyperlink format formula editor in crystal reports can handle this.

What I did in excel:

HYPERLINK("mailto:"&$A$1&"?cc="&$A$2&"&subject=TRD INQ: "&B9&"  |  "&E9&"  |  "&F9&"%  |  "&I9&"  |  "&H9&" &body=CUSIP: "&B9&"%0AAmount:%0AAccount:%0ASub Account:%0A%0ADealer: "&Y9,"SEND")

this excel formula handles creating the email and populating the To, CC, Subject, Body.

Dear Guys, please assist this scenario:
- Action: We changeed Email server from Gmail to Exchange 2016 On-premise, so we had to change the domain records in Domain control panel. We changed TXT, MX, @, mail records.

- Problem: After changes, the new Exchange server worked (send/receive emails) normally as expected, however we realized that we could still login to Gmail account, Google Drive and sent emails (but could not receive emails)

So can you please explain?

Does Migration Wiz migrate all emails, calendar items, contacts, tasks, etc. from Gmail into Office 365?

Or does it only migrate emails?

Dear Guys, we are deploying Exchange mail server. We knew that the Mail server must be published with an public IP address (and registered with A, MX, TXT records) but is it mandatory for an Active Directory (of mail users) Server to also have an public IP address and to be registered (by A record) in domain control panel?

Many thanks in advance,

I am having an issue with getting vcenter emails working. Vcenter 6.0. Mail server is set to a ip of a working iIs smtp relay for another application.  The working iIs smtp is working for 10 other server applications. Logs are saying "550.7.60 client does not have permission to send as this sender". I granted the vcenter ip relay permissions on the smtp server. I can't figure out why vcenter emails can't make it's way out the smtp server but the other applications can using the exact Office 365 email account. Thoughts?

I had a spam problem about a month ago, which I fixed on my end.  I notice now that email I send to recipients at gmail are automatically being marked as spam.

My mail server is Unix - Communigate Pro running on an old PowerMac. Outbound mail goes to my SMTP server, which is a Dell SonicWall ES-3300    I changed the IP address after the spam got past the SonicWall, and put the new address into my DNS, which is hosted by DYN.com

I looked at the header of a message I sent to my gmail account.  I see something wrong with the SPF record

Dear Zealots, do you know any method to show the statistics in Google mail's usage. For details, we would like to have the report showing the frequency of email flows, like how many emails in weekdays and weekends, from 8 AM to 5 PM, from 5 PM to 10 PM, etc.

The same question in MS Exchange server. Can you please suggest? Many thanks in advance!

Update1: I found Gmailmeter, it could show me my statistics, but how can I see my end-users'?

My OS is win 10 pro 64 bit and I have office 365 and outlook owa for my emails , which is an MSN account the free version.
Whenever I see a sender of an email in the Junk folder, despite clickking on the "Not Junk" selection and it goes into the Inbox.  But after some time it still seems to land in the Junk folder.  
how do I make it safe emails coming to me to my Inbox without it going to my Junk email, or is this one of the misses that sometimes always takes place.
The error says that it failed the fraud detection test or something like that.
Thank u.

Dear EE

Please can someone tell me what's the difference between the "From" and "X-Sender" field in message header?

We recently had a spoof and phising attempt on one of your users.

I have SPF in place and it works but it didnt stop this email because the X-Sender address is not that of my domain. My SMTP domain is TTAF.co.za

Please see image:

Where within the Gmail admin console can the external DNS mail exchange (MX) records be changed for an organization using Gmail for its email?

We have recently migrated from Exchange 2007 to Office/Exchange365. Since migration we have received a number of email rejections on one specific email indicating "your email program added invalid characters (bare line feed characters) into a message you sent".

The email itself comes from an HTML template and generated in Microsoft Dynamics AX. This is directed email to customers and is consistently accepted by some downstream providers (eg gmail, Hotmail) but not others (eg Yahoo, Comcast).

The HTML code that comprises the body text has been scrutinized and does not contain any bare LF's, nor has it changed since long before the migration.

Support from Microsoft, Yahoo and Comcast has been of little use (for the most part unwilling to engage other than throw out generalities to get you off the phone).

Key facts;
- email was working prior to (Exchange 2007 to Office365) migration
- other (text) email to affected customers is delivered without issue (ie limited to one HTML email)
- originating email has been checked for bare LF's


As this email was working previously I have the following questions;
- have you seen and resolved similar issues?
- As this was working previously I am wondering if Exchange 2007 stripped out bare LF's in order to fix (my understanding is that Office 365 was but stopped doing so).

Please do not suggest online articles found by Google searches unless you feel there is something very specific we can look at. We have searched …
