Email Clients




Articles & Videos



An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.

When a Collegue of mine add's a mailbox to his outlook, that mailbox wil only get mail when u manually hit Send & Recieve. A few other collegue's of mine experience te same problem. But when I add the mailbox to my outlook it does get mail real time, so I don't have that problem.

They al have a few mailboxes in their outlook but even when I remove all mailboxes and add only that specific one, it doesn't recieve mail  unless u manually hit send & recieve.

Microsofts best practice is working in the OWA but that is not an option, does anyone know how to solve this problem?

I signed up at the Microsoft Stream Preview website, using an Personal Microsoft Account ID, not realizing that it was a service meant for Office 365 for Business. Usually Microsoft websites check if the account is a business account or not before accepting he email id. Microsoft Stream, however accepted my Personal Microsoft Account ID and signed me up, classifying the ID as a Business Microsoft ID as it created an Office 65/Azure tenant.

Was unable to access mails at which came up with a something-went-wrong error message when we tried to sign in. A little research on Bing (yes, I am a loyal Microsoft Insider) and I found that the solution was to switch my primary e-mail id with an alias.

Lumia 950 with Windows 10 Mobile, Version: 1703 (Build: 10.0.15063.414)
Surface Pro with Windows 10, Version: 1703 (Build: 10.0.15063.413)

Surface: Everything works with the new primary alias
Mobile:  Mail and People Apps on the Mobile not syncing (Error code: 0x85010014)  Error Message with the new primary alias. Everything else works

Deleting and re-adding the Mail/People accounts about 50 times. Tweaking the settings in the Outlook account trying different sync and mail server settings (hotmail/eas). Hard resetting the Mobile as the Apps | Apps & Features | Advanced Options | Reset button is greyed out.

I have one client that cannot email me.. They receive a bounced back message saying;

550 Verification Failed
No such user here
Sender verification failed

I can however email them. But they cannot reply.

None of their emails from their domain will come through, however I have been guaranteed from my ISP (crazy domains) that there are no blocks on my end. However i do know of another company who are with crazy domains are experiencing the same problem with the server  

As I run my ow  business, my only option is to change hosting companies in the hope that works.

Would love an easier fix
Hello All,

Does anyone know of a free, safe conversion tool or method for exporting Thunderbird email to Outlook 2016?
Hello, I want to export several thousand emails from Windows Live Mail 2012 to Outlook.  I'm trying to use WLM's inbuilt Export to Exchange feature.  There are 1,020 emails in Inbox, and then there are loads of folders within the Inbox, with another 4000, roughly.  The process begins fine, and when reaches email number 684 of the Inbox, out of 1,020 (always the same email), WLM crashes, and the process halted.  I've heard of other people having the same problem as well, and when they try to open the offending email in WLM, they get an error - which suggests corruption in the email.  However I have no idea how they found which email it was that wouldn't open.  How can I tell which email number 684 is, so that I can just delete this and carry on.  I obviously can't open every email in my Inbox.

Any ideas?

I know there are 3rd party paid apps to do the migration for me, but I'd like to see if I can do it this way first.

Hi  I have several issues with my outlook, I am on a windows 7 64 bit MO with outlook 2010, over the past 4 years the following is happening;

1 emails are coming into my inbox and randomly being flagged for follow up and either left in my follow-up section on inbox or being moved to a random folder this is without them being read
2  emails are coming into my inbox and the being marked as completed without me reading them
3 previously flagged items are randomly returning into folders or my follow up folder
4 email account sends out random meeting requests this could be last year, yesterday or from 4 years ago!
5 some emails are not being received and yet the person at the other end of the email has a copy with date and time, the exchange states the email was received but it's not in my inbox
6 emails that I sent are not found in my sent items or even mailbox, yet the person at the other end has a copy of my email I sent to them

So far I started with an Excel document issue and from then til now 4 years I have had horrendous issues.  

IT have given me 4 new laptops, they are great and no issues until about 4-6 months down the line when they are clearly visible and I am convinced I'm not crazy or losing the plot.  I had no phone synced to my email account when the issues started happening, repaired email accounts, created new email accounts, the only thing that works for a short period of time is a new laptop install, also I seem to be the one who uses the flagged …
I have a group of 25 users on a domain that are using remote desktop access to a common server. They use a program on your server that requires them to use Outlook to send reports, invoices, etc.  

The email addresses they use our Gmail hosted, and some of these users have ridiculous PST files.  What is the easiest way to set up a Outlook 2007 or 2010 profile that does not bring in any data from the Gmail servers.  Essentially would just be using them to send  mail
What would cause an end user to receive some of their emails hours later after they were sent. This only happens occasionally (not with every email)
The name cannot be resolved.The action cannot be completed.Everytime i get this error while setting up my outlook account

My users recieve an occassional message from a local bank with a link to a message in the bank's secure communication system.  It usually looks like a html formatted message with a table showing the list of messages and each message is a link which takes you to a log in page where you use your credentials to access the bank's portal and read the messages.

Recently the messages have been coming in garbled.  Apparently the issue is caused by "Content-Transfer-Encoding: base64".

The messages appear garbled in Outlook and OWA.  I read that it was just a problem with Outlook, but the messages are also garbled in Thunderbird.

The bank can't or won't change anything.  Office 365 tech support didn't have a solution.

If anyone can think of any other steps I can take to rectify this situation I would greatly appreciate any advice.

Best regards,

I have deleted am original sent email and only have a copy I have forwarded on..  Is there any way to recreate the original one and have it in my sent items folder..   It super important
My current problem is that when using the .Address function I get returned an address that isn't the email address I want but the last entry in the email addresses list. Is there any way for me to specify which address i want

an example of the contact's email address list would be

and it would return the 0xf218Hi=There when using .address
Why can't I see the intended content in the emails I receive? I constantly get redirected! How do I fix this?

How do I transfer my email address auto fill from one account from another in Office 2016?
In older versions there used to be an NK2 file, but I can't find it in 2016?
This is probably really simple for someone but I am not 100% clear on what IP address to check when there are potential blacklist issues for email. For example - other than the SMTP email server address - what other addresses (if any) need to be checked to ensure there is not an issue with being blacklisted that will affect some recipients from receiving emails?
(Assume hosting service email, not internal email server)

Basically - I think that only the SMTP address needs to be checked - but do not know for certain if other content for routing that is in the email header is a factor for being blacklisted.


Two users

User1 can't email user2 in Outlook

All else working fine

Pop and imap is enabled - which is possible in gmail

Two PCs pop accounts

iPhones - imap

Why can't these users on same .com email each other

Both accounts are white listed in outlook
No odd tools / rules
We users in iPhone that created custom  labels in their Contacts area.  These in turn sync to Outlook various fields.   We are trying to read these fields from Outlook.  Any EE has a script that  reads Outlook contacts info or how can we go about?

Had issues with ActiveSYnc timing out on Exchange 2010 SP2 RU4. Updated the server to SP3 RU17 on May 20th.
Only the activesync timeout problem for 3 Users existed prior to this update. These activesync issues remain for the three Users (not the focus of this question) and new issues are seen (focus of this question):

Total of 15 Users out of 250+ affected with this new problem. These Users are not the same with the ActiveSync issue:
1) For SOME Users all shared mailboxes in Outlook no longer populate with emails or auto-update immediately after the updates.
2) For SOME Users, this issue appeared to start a full week later.
3) For ONE User, only one of three shared mailboxes in Outlook are not auto-updating.
4) Selecting the folder in Outlook ,choosing the 'Send/ Receive' tab and selecting 'Download Headers' then 'Update Folder', allows the emails in these shared boxes to populate with new emails (since the last time this process was manually run).
5) Win7 Pro for all but two Users, who are on Win10.

What I have tried (not necessarily in this order):
1) New Outlook profiles
2) New Win7/ 10 User Profiles. Tried this because loading two of these Users' profiles onto a different, unused laptop works fine.
3) Deleting the .OSTs manually and rebuilding
4) Cached Mode/ Online Mode
5) Deleting the autodiscover xml record in the Outlook profile folder. Did this in case that file was corrupted and was not pulling the shared mailbox info properly.
6) Saw a …
nothing i do sets it permantently in the main folder. how can i fix this?

I need to change an Outlook 2103 email address from POP 3 to IMAP.   I backed up the account , deleted it and recreated it as IMAP.  Now when it import the pst file I get the following Outlook error

'Your imap server wants to alert you to the following:you exceeded your mail quota'

I have been in touch with the hosting company and they say there is no quota issue in their side.

Any help greatly appreciated
How to define the SMTP OAuth2 for Gmail on an Android 5.1 phone?

On my Windows 10 Phone I have the definition for SMTP like this:

-> smtpa.xxxxxx.yy:465:1

on which the digit 1 means -> SSL/TLS -> regular password

On the Android 5.1 phone for Gmail I should be using something like that, but can't figure what should be the definition in full for OAuth2, for example


on which the digit z should be meaning -> SSL/TLS -> OAuth2

or, am I on some wrong direction with this?

Anyway, the Gmail account do not send any mails on this phone with several different alternatives on this on several trials ...

Please, help, if there is a solution for this.
Hi, I have a issue. Our WP web server has been compromised and has been infected with a spam-sending virus. We have cleaned the infection but we got to many spamlists including The problem is, that we have never used this server (IP) as a mail server and we are using google services (not only) for emailing. We have made actions to block any smtp traffic from or to our web server. But that aslo means that we are not able to send de-listing email from our  IP.  This is a "catch 22 situation" when we are not able to send mail from that ip but the server still keeps record that we used to spam and some of our customers' mail servers deny our mails as spam because they check our domain IP which ends on this IP... . How to get out of that? Is the only way to start webserver on that IP and send delisting mail? I would really hate to do that...

We just had to change our email from verizon to AOL and I changed it all right but when I wanted to reply to an email I had to push compose becauseI could not find a reply button.
Hi, I have a client whose email is hosted exchange and has asked the following question:

'I have heard of a system whereby the boss of a company is automatically notified if any staff have unanswered emails at the end of each business day. It also tells the boss if an employee has not filed his/her emails appropriately in the corresponding “boxes” - do you know of this?'

I don't know of such a system, does anyone out there?

PS it is a small business with about 6 employees - so the budget will not be huge...
