Does Outlook work on Windows 7 or Windows 8?

Manufacturers and retailers often offer the current version of Office with the purchase of a new computer, sometimes with a discount. Should you purchase the new version or save your money and keep the old (and less secure) version?

While Microsoft says the older Office versions are "not compatible" or "not supported" this doesn't necessarily mean "won't work". It just means that you might have issues and can't call Microsoft for help. You are on your own. This page lists some of the issues you might run into. If a feature you use is negatively affected, you probably should upgrade Office too.

Do not enable compatibility mode – this is not needed and will cause problems with any version of Outlook.

Outlook 2003:

For issues involving Outlook 2003 on Windows 7 or Windows 8, see the following pages:

Outlook 2000 information is now at Outlook 2000 on Vista & Windows 7

Naturally, Outlook 2007, 2010, and 2013, work well on Vista and Windows 7/8. (Outlook 2007/2010 also work great on Windows XP; Outlook 2013 is not supported on Windows XP.)

Outlook 2003 works well on Vista but there are a few problems with it on Windows 7 (see links above). Both of these versions are officially supported on Vista and Windows 7, so if any issues arise Microsoft will offer public hotfixes or include the fix in future Service Packs.

Outlook 2002, 2000, 98, and 97 are not supported on Vista or Windows 7 (or any later versions). If you choose to install any of these applications you should expect errors and annoyances. The better known problems are listed below but there may be others I'm not aware of. These versions of Outlook are all long out of support and Microsoft will not release patches to fix any problems with these versions. Upgrading is highly recommended, or use the new Vista calendar and mail applications if you are unwilling or unable to upgrade.

Outlook 2002:

It runs, but email account passwords are not saved. After you enter the password during the first email check, Outlook will remember it until you close down Outlook. This is because Outlook used the protected storage interfaces to store passwords and these are no longer supported in Vista.

One possible solution is to run Outlook as an administrator. Right click on Outlook shortcut or Outlook.exe and choose Run as Administrator. If you don't see the Run as Administrator command, Shift + right-click to enable the Run as Administrator command.

OLAutoPW automates the Network Password Entry for POP3 and IMAP accounts in Outlook 2002/XP SP3 on Windows Vista/Windows 7.

You can use a Windows script program such as AutoIt to enter the password for you.

Note that when you enter the password, the Send and Receive that brought up the password dialog may fail but future send and receives will work. Leave Outlook open 24/7 to avoid entering it frequently.

Recurring calendar items may not open. This may be related to opening a single event in a series from the Day/Week/Month view. Open the event using any List view, such as Recurring Appointments (View, Current View, Recurring Appointments). It may also work to open the entire series from the Day/Week/Month view, I haven't tested it yet.

Outlook 2000:

Now that the list of workarounds is growing, thanks to our readers, I moved Outlook 2000 to its own page at Outlook 2000 on Vista & Win7.

Outlook 98:

Like Outlook 2000, IMO mode will not work because of the missing wab.dll. I haven't tested it with Corporate mode yet, but I recommend using Vista's Mail and Calendar programs instead – Outlook 98 is just too insecure.

If you are unfamiliar with the difference between IMO and Corporate modes, see Choosing an Outlook 98 or Outlook 2000 Mode.

Outlook 97:

Not tested. Because of the lack of features, buggyness and slowness, it's highly recommended that anyone still using Office 97 either upgrade or use the built-in Mail and Calendar apps instead.

    Are you using Compatibility mode? That is not necessary and can cause this error message. http://www.outlook-tips.net/configuration/troubleshoot-compatibility-errors/

    Did you try resetting the navigation pane? http://www.outlook-tips.net/tips/tip-657-unable-to-open-the-outlook-window-error/

    Note that Protected Storage fix at that link is not from Microsoft - use at your own risk. (It also puts Windows 7 into an "unsupported mode" but most people don't go to Microsoft for support anyway.)

    Generally speaking, most apps should run on it. I'm not familiar with how this program works, but I'd try setting the properties on the program to run in compatibility mode. Or see http://www.shadowbox.ca/KnowledgeBase/Class_Not_Found_Error.asp - they say to insure you have the latest media player and flash and also to install it in C:\Learnkey also see http://www.shadowbox.ca/KnowledgeBase/Install_problems_with_Vista.asp

    I can provide an update on Outlook 2002 and Windows 8 (64 bit). It does work although the password problem is annoying. However, this can be overcome by using OLAutoPW (see link above) which works very impressively.

    One point to mention is that I couldn't get the Windows 7 version of OLAutoPW to work on Windows 8 (even using the compatibility mode settings) but v201 for Vista does work well (NB using compatibility settings for Vista).

  • Victor

    Spoke too soon! OLAutoPW works fine for the trial period but I am advised by the German software creator that unfortunately the registration process will need changing to work with Windows 8 and that will not be done owing to the low number of users requiring it. Understandable I guess. So perhaps I shall have to see if i can find a copy of Outlook 2003 (to avoid upgrading to ribbon toolbars etc!).

  • http://www.outlook-tips.net Diane Poremsky

    Too bad they can't provide you with a registration-free product. :( Check eBay or sites that sell close-out and older software.

  • Floyd Hamilton

    I have Office, but messages pop up that I have to have Office in order to get Outlook. Isn't this a "Catch 22"? What do I have to do to correct this? I have Windows 8.

  • http://www.outlook-tips.net Diane Poremsky

    what version of outlook do you own? what are you doing when you get the error?

  • danny antony

    Hello Diane

    I have got to this page because I am having a real problem running Microsoft outlook 2002
    with email account ( passwords ) on my windows 7 machine - as your post points out the passwords for the 2 accounts I have must be continuously manually added, which is becoming very annoying. everything else works fine.

    I downloaded AutoIt and installed it ( I know my way around PC;s and software etc ) but I have never written scripts. ... I have followed instructions and successfully created batch files but that is about it.

    I downloaded the 64bit version of Autoit and installed the run script version ..

    I am sure this will be very simple for you but can you please tell me what bit of Autoit I should launch ( I have a few progs in my programme folder ) and how do I actually go about making this programme input my password when I launch Microsoft outlook 2000 ?

    I hope you are still monitoring this page or if somebody else can help me I would really appreciate it.

    Kind regards

    Danny

  • http://www.outlook-tips.net Diane Poremsky

    I have not used autoit for this purpose, but will try to to figure out what you need to do. I'm sure there are other people with the same problem, but don't want to ask for help.

  • danny antony

    Hi Diane

    I managed to get a work around for this problem - I found a post that wrote a specific instruction that seemed to work for some but not for others - I was lucky and it worked for me.

    I do not want to put you to any trouble so please do not worry about finding a fix for me specifically

    I am very impressed that you replied - you are doing a great public service.

    Kind regards

    I am having issues with Outlook 2003 SP3 on my Windows 7 Pro SP1 desktop computer. It worked fine until about a week and a half ago. Then it began doing two strange things.

    First - I have it to set to automatically spellcheck when sending. It would find an error and offer suggestions. I would choose the correct spelling and click the Change button. The message is then sent, but without the correction I indicated.

    Second - Outlook started cutting off my emails when I send them. When I type a new message and send, everything is fine. However, if I go back to make a revision, that's where the message is cut off when I send it. The recipients receive an incomplete message.

    I have been told this is likely the result of a bad Windows or Microsoft update, but I have not been able to fix it by doing a System Restore or uninstalling any updates. I tried uninstalling Office 2003, and doing a fresh install, but that did not work either. Now, I am facing a complete system rebuild. Is anyone else having these issues? Can anyone offer a suggestions to fix this?

  • http://www.outlook-tips.net Diane Poremsky

    Does it work correctly in Safe mode?

    Did you post this on other sites? If not, there is more than just you with this problem.

  • Samantha Grower

    Hi, Diane,

    I am not sure about Safe Mode; I will try it and let you know. I have been working on a separate hard drive with an older working image of my computer to see if I can isolate a Windows or Microsoft update that causes Outlook to manifest these issues. no luck so far, but I will advise if I learn anything on that front.

    I have not posted this on other sites, and I know there are 6 of us in my company alone having these issues. I looked on other sites for ideas / suggestions / solutions, but did not find anything that solved this problem.

    Samantha

  • http://www.outlook-tips.net Diane Poremsky

    Oh, since you haven't posted anywhere else, there are others with the same problem. That means its probably not something you did. It could be an addin or another application causing problems.

  • Samantha Grower

    That's what I think too, especially these issues did not start for all affected users at the same time; they appeared over the last two weeks or so. That's also why I am suspicious of the Windows / Microsoft updates; they are released on Tuesdays.

    Any suggestions as to which add-ins or software might be causing this?

  • Samantha Grower

    Hi, Diane,

    I have now tried my email in Safe Mode and confirmed that the issues persist.

    Samantha

  • Samantha Grower

    After spending many hours installing Windows / Microsoft Updates one at a time and then testing my email, I have determined that Internet Explorer 11 is to blame. After uninstalling it, restarting, and then hiding it to prevent Automatic Updates from reinstalling it, everything is working properly again.

    Thanks for the update!
