Hotmail was the first free webmail service to enter the market in 1996 and has led to a dominant position for a long time.

Of course, it’s not just the Hotmail name that’s been known for more than 16 years that has changed at all: from social integration to multimedia extras, there have been many surprises in web Outlook.

    The @ e-mail addresses are still available and usable, ie if the sender writes to any Hotmail address in the future, the e-mail will arrive in the account. Hotmail was formerly known as Windows Live Hotmail and also MSN Hotmail.


    Why Hotmail has been transitioned to

    Since the launch of the email service, it experienced many changes, including one not very successful re-branding. Despite this, Microsoft continues to experiment with its email, and today the Hotmail brand has faded into the background ad has paved the way for the new service.

    Inside the company, the reason for the next re-branding is because of the not-so-good image of Hotmail, which seems to have forever gained the fame of unreliable and slow email. The main cause for the downfall of Hotmail is the arise of Gmail which came in the market luring many Hotmail and other email users by offering any features that these email services didn’t have at the time.


    Thus, Microsoft decided to compete for users using a different name, and since the only Outlook is directly related to email among the company’s products, it is known to a sufficient extent, the choice fell on it. Eventually, came with the ability to save your data and address, or register a new one. has, in fact, many more features that the Gmail and other email services don’t have. With Outlook, Microsoft has been able to get back its lost users to Gmail. Many have defined the as the Retro Style Hotmail. One of the best things that Microsoft did with Outlook is it enables people to use their old Hotmail address in

    Features of email service

    The has included many features overcoming not only the failures of Hotmail but also competing with the features of Gmail. Some of these features are still those which many users may not know to exist in Take a look at these features of

    1. Inbox

    The first thing that catches your eye when logging on to is the new inbox interface, which is made in the Metro style and is very similar to the standard mail client for Windows 8 and 10. The user has the opportunity to choose the main color, it will be painted the top panel, as well as links. In addition, the Inbox has two additional types of display. Letters are grouped on the topic of correspondence, which is very convenient for prolonged communication with one or more recipients.

    In the left column is a search bar, folders, as well as links to message groups with photos, documents and important correspondence. The user himself can create a folder and the rules according to which letters will fall into it. Otherwise, looks different from Hotmail, but the service structure remains the same; for active Microsoft mail users, the new interface will not seem completely unusual.

    2. Composing new message

    At first glance, the design of the message compilation window looks very unusual, since the address bar is on the left side, and the message subject and text of the message itself are centered on the screen. Nevertheless, you quickly get used to such a design, it does not seem too complicated, on the contrary, large interface elements allow you to quickly navigate. When writing a letter, you can switch from the input mode of formatted text to plain or HTML.

    There is also a panel with basic formatting tools, you can choose one of nine fonts and its sizes. The spellcheck button is present which on pressing will check all the spelling of your message. Adding attachments to is implemented by a special button that allows you to transfer files from your computer or mobile. It is convenient to correspond through, you quickly get used to the interface, and it pleases with its simplicity.

    3. Strong mailbox

    The mailbox of the free e-mail offer is 15 gigabytes in size and therefore offers long-term space for numerous messages. There is a direct connection to the OneDrive cloud storage, whose storage space is measured separately. Attachments of up to 25 megabytes in size can be sent directly via Outlook. Outlook automatically transfers any larger data to the OneDrive cloud when it is sent so that there is virtually no size limit when sending mail. Your Outlook and Skype contacts are also conveniently merged, a seamless transition between the two platforms is created.

    Navigating between folders is very clear and a powerful search function is available. If you want, you can create alias addresses that allow sending and receiving emails from alternative addresses from an account. Forwarding rules are also quickly created. As is typical for Microsoft, some of the setting menus are unfortunately rather confusing.

    This is due in particular to the fact that Microsoft repeatedly refers to alternative company-specific pages for profile configurations. However, this inconvenience does not affect Outlook itself. Microsoft completely does without advertising: fortunately, no annoying ads land on the website or in the mailbox itself.

    4. Connection to office

    In Microsoft’s online interface, you can easily switch between mail and office applications: Word, Excel, and Co. can be called up easily with just one click in their web variants. The sharing of documents via e-mail from the office applications also works well.

    6. Spam protection

    Outlook protects you against annoying commercial emails and other spam with the help of a spam folder. All e-mails that should not end up in your mailbox are reliably sorted into these – but sometimes the spam filter is too hasty because important e-mails sometimes end up in the spam folder.

    7. Safety

    Microsoft offers solid security features when dealing with emails. This includes encrypted registration in the webmail interface, the encrypted data transmission there and also the e-mail access secured with TLS Forward Secrecy via the SMTP server.

In the window that appears, you can select a search folder from the templates provided by Outlook, or create your own yourself.

    For example, the search folder Unread emails will show all messages that you did not open, regardless of where they are and what accounts they belong to. Emails will not move anywhere: only links to them are displayed in search folders. If the Outlook templates do not suit you, select Create a custom search folder at the bottom of the list. Click Select. Then enter a name for the folder, click Conditions and indicate by what criteria you want to select messages in it.

If you need to cancel the delivery delay or change the date and time of sending, open the Outbox folder and look for your message there. Click Delivery Delay on the Settings tab and change the date and time in the Do not deliver to the field. Or uncheck the box to disable the delivery delay.

    What is the maximum file size that can be sent via Hotmail?

    Microsoft has raised the maximum limit of email attachments to 150MB for users of Microsoft Outlook email services. Users of the Outlook Web Access e-mail service from Microsoft under Office 365 can send attachments ranging from 1MB to the highest of 150MB. Microsoft also sets different limits for different groups of users. Although it can send attachments up to 150MB in size, it doesn’t mean that users can send 150MB attachments in one email. Microsoft sets each email limit at a maximum of 25MB.

    Outlook Web Access limits the size of messages that can be sent is 25 percent less than the maximum send size. It means that if the attachment size is allowed 100MB users can only send 75MB and each attachment can be no bigger than 25 MB, so users can send three attachments, each measuring 25MB.

    In addition, there is no guarantee that people sent email attachments up to 150MB will be able to receive it. Because it could be that the file is too big to download or there is a maximum limit of emails set by the Office 365 recipient. Although Microsoft can now send large email attachments, users are still advised to send large files using the cloud.

    Sending larger files more than 25 MB size

    The outlook is an e-mail service from Microsoft that offers filtering functions so that it can filter any e-mail from whatever origin. Outlook e-mail also allows automatically sending all e-mails from certain senders to specific folders.

    Method 4

    Usually, the larger files that you want to send via email are the image files. The other simple method is to decrease the image size and then send it. For this, you have three options.

    Option I: Inserting a picture in the message body and then resizing it
    • To insert a picture in the body of your message, place the cursor where you want your image to be. Then click on Insert and choose the picture. If the size of the picture is large, you can change the size of the picture by using the sizing handles. 
    • Tap on the photo so that a small circular sizing handle at each corner of the picture will appear.

    • Attach the images that you want to send to your email message.
    • Then click File > Info.
    • Under the Image Attachments section, you have to select Resize large images when I send this message option.
    • Now, return to your message, and click Send, while doing so, the outlook will automatically adjust the size of the image.

    Method 5

    In another method, you can save the file you want to send in a SharePoint server library. It is useful especially when you are using outlook email for business purposes. Follow the steps given below:

    • In Word, click File > Save As > Add a place where you want to save your word file.
    • Under Add a place, click on the service that you want to use, like Office 365 SharePoint or OneDrive.
    • The Sign-in screen will appear for the service that you have chosen. Complete the form, remember you may have to contact for the username and password to your IT Department.

    • Now open the file that you want to share. Then click on File and then click on Save As.
    • On the Save As an option, you have to double click the location that you want to use. Such as your SharePoint document library, a location on your computer, your MySite, or your OneDrive.

    • Under Share with People (or, in Word 2013, Invite People), type the names or email addresses of the recipient you want to share the file with.
    • If you want to give more rights to the recipient, then you can select Can Edit or Can View. It will allow the recipient to edit or only view the file.
    • Enter a message in the box below the address line, this is optional, then click Share.

    Method 6

    Add Outlook Attachment Size Limit

    By default, Outlook can only send an email with max attachments of 25MB, and many mail servers that allow attachments more than that may be more than 50MB. Now if we upload file attachments in outlook windows more than 25MB, the error attachment size exceeds the allowable limit error will appear. You can overcome it by setting the max attachment via the registry. Follow the steps given below:

    • Press on the Windows keyboard + R.
    • On the run menu dialog type Regedit. and type OK.
    • Arrange on the menu as below:
    • Outlook 2019 and 2016: HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 16.0 \ Outlook \\ Preferences
    • Outlook 2013 : HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 15.0 \ Outlook \\ Preferences
    • Outlook 2010 : HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 14.0 \ Outlook \\ Preferences
    • Double click on MaximumAttachmentSize.
    • If you don’t find MaximumAttachmentSize, manually add the added registry> Dword Value and fill the value with MaximumAttachmentSize then enter.
    • In this case, the maximum file size is specified in kilobytes (KB). If you know the maximum possible size of file attachments from your mail provider, you can easily calculate the necessary values. You simply multiply this number in megabytes by 1024. Now you have to enter this calculated value in kilobytes. If you want to completely deactivate the warnings, you can set the value to 0. Such as for 2MB -> 2048, 5MB -> 5120, 10MB -> 10240, 50MB -> 51200.
    • Increasing the maximum file size for attachments in Outlook does not automatically increase the maximum file size for messages from your email provider. For example, if the server limit is set to 5MB, larger messages will still not be transmitted and you will receive corresponding error messages and warning messages.
    • In this case, the only workaround would be to split the too large file into several small parts or to use a file hoster.

    Method 7

    When everything fails, then take the help of a specialist. The easiest way to spontaneously send large files of any kind are services that specialize in them. Perhaps the best known is Wetransfer, which can send up to 2 GB in one go. Simply enter the address of the recipient and your own, pull in the attachments and click on Send – no registration is necessary.

    Wesendit is a recommendable Swiss cloud sender that sends up to 5 GB free of charge and continuously encrypted without registration. Free customer data is automatically deleted after seven days. Droppy is also based in Switzerland. This service also sends up to 5GB free of charge, the transfer is SSL-encrypted and files are deleted after five days or earlier at the user’s request.

    Minbox is an interesting alternative for teams. Here files can be uploaded from the computer or the user integrates other cloud services. It is possible to share files individually with team members or to combine them in projects. The US service works in the browser, a program is currently only available for Mac OS. The free storage space is 2 GB.

    With the German service, Zeta Uploader only 500 MB uploads are possible free of charge, the email address of the recipient is sufficient and the file can be protected with a password.
