Email Clients





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.

Last week I opened my Outlook email (pop3) and noted that I had around 1700 unread messages, I thought, oh boy they found me expecting to find a ton of spam, but no.

While much of it was spam, a great deal was email I wanted to get, and it all arrived that day but was sent as long as 6 months before.   This was from sites like zip-recruiter, dominos, Dell, and multiple other domains.

I have been receiving mail from all of those sites, these were messages that simply sat somewhere in limbo?  

I changed my email password.  But I have no clue as to why this happened, or if it is going to happen to others, where do I look for answers?  The server logs only indicate that they all arrived the day they did. It seems like they were being "held" somewhere.

technical notes:  I do have my account on my phone (IMAP - turned that off), using ALT-N Mail Daemon (not exchange), NO one else (132 users) has reported this issue or anything even similar.

I have a single User that cannot connect his Outlook Client to the Exchange 2016 Server.

When setting up the Outlook Client, i can't get further than the Password request. (It just reappears a, sugesting that the password is wrong)

The User works normally in OWA.

We have Outlook 2016 in use, the Failure is not specific to a single Windows Client, it can be reproduced with any Windows Client.

Other Users can be setup normally on each Client.

I have the Same Issue with 2 different Exchange Server at two different Customers...

Test-OutlookConnectivity works fine
Microsoft Test Exchange Connectivity works fine (Even using the "faulty" user)

Funny Thing: I deleted the User and his Mailbox completely from the System, after I recreated the User, I still had the same Issue.

The Only way I know of currently, is to give the user another external SMTP Adress, this seems to solve the Problem temporarily...

But that Solution is not acceptable for our Client.

PS: Setting up the User via Autodiscvover externally works "sometimes" (On some machines it does, on some it doesn't)
My Outlook 2016's new emails notifications arrive quite late:
did not time them exactly but all of them pops up about 30 mins after actual email arrival;
attached is one such notification.   I'm currently on O365 Exchange.

I recall previously when using Outlook 2010 (on-prem MS Exchange), notification is

pops up quite timely
When I tried to attach a few large video files in gmail, it auto-prompt to
attach via googledrive due to the size limitation:
after that the used quota became very high.

Meant to save the emails as draft for friends to access (ie sharing).

However, from my gmail, I could not locate the video files from the
draft/Sent folder.

Need to bring down the used quota of gmail: so how do I locate
those files in google drive to clear them away to free up space?
After saving an Outlook  Meeting  or  Appointment, where did it go to?

Hello Dears,

As you can see from the attached images, email headers are not showing in the emails list pane. also the Reading pane is showing the raw email content, headers and encrypted message.

other email clients are showing the same email correctly.

tried to:
     -uninstall/re-install of Office 2010, 2013, 2016 none has worked, all of them show the same problem. even cleaned Registry after the uninstall.
     -repair pst, create a new pst file, all have the same issue.
     -disabled McAfee , removed McAfee, installed AVG nothing changed.

none of the above worked.

the conclusion I came to is, there might be a setting somewhere that is telling outlook not to parse the email, and only to view a raw message .. but I searched many forums for a solution with no luck.

the office is installed on windows 10.
emails listmessage looks like encrypted
Email sent to a Yahoo user are received showing HTML formatting.

One of our user is missing there inbox.   After researching we found the inbox was somehow moved outside of the root folder.     It located outside of the "top of information store"   how can we move this back?
There's a new scam out there where someone receives an email that claims that the person sending the email is going to send everyone in their contact list a message saying that the person is visting porographic web sites.  The email usually contains one of the persons valid password that is currently in use, so they definitely have been hacked somehow/somewhere.

If you've run into this and discovered how they are getting the passwords I would appreciate your sharing the information.  None of the machines show any indication of having malware/viruses on them
which is the best way to write a copy of calendar permissions using exchange powershell cmdlets for a maibox, out to csv file for analysis.
By calendar permissions, I mean those which in outlook 2010 > calendar > calendar permissions. It lists a list of accounts I've shared my calendar with, and also some strange entries for "default" and "anonymous", whatever they represent. I need to check for inconsistencies across over 60 calendars which should all be shared in the same way.
Hello everyone,

After 02 months, my ISP finally helped me with Reverse DNS / PTR records. Now when I test my email server on MXToolBox, it states the following error on MXToolBox:

1- Reverse DNS does not match SMTP Banner

My email client is also not able to login to the IMAP. Previously, the email client could login to both IMAP/SMTP and only email was being rejected due to no PTR record.

I believe the tech guys at ISP didn't enter it correctly. The domain is caretakers.pk

Any help would be highly appreciated!

Thanks and regards,

Windows 10
Outlook 2016
I have Microsoft Office 2016 and I am using Outlook to connect to AOL (verizon.net) email. I have a lot of folders and email I want to keep. Recently, Outlook stopped RECEIVING email and nothing I've tried seems to fix it. (FYI, I obtained MS Office Professional 2016) from a prior job, and reinstalling it prompted for the key, I don't have it).

So I have downloaded 4 windows email clients (eM, Mailspring, Thundermail, Opera), all fail to download email contained in "custom" folders defined in AOL.

Any ideas?
An employee just received this email.  Sounds phishy.  There is an attachment that looks like a word doc, but is a link.
