Outlook Won’t Work in MacOS High Sierra – Fix

By 40 Comments

If you’re running version 15.32 of Microsoft Outlook for MacOS or lower, and have upgraded to MacOS High Sierra, you will receive an error that says “You can’t use this version of the application “Microsoft Outlook” with this version of MacOS“.

You can fix this problem with these steps.

  1. Open Microsoft Word, Excel, or another Microsoft application.
  2. Select “Help” > “Check for updates“.
    If you don’t see this option, or if you don’t have an option to update, download and install AutoUpdate.
  3. Walk through the wizard to update Microsoft Applications. You will be able to upgrade Microsoft Outlook.

Once updates are complete, Microsoft Outlook will work in MacOS High Sierra.

  1. Thank you so much for this information. Now I can access my contacts again. It makes sense but I didn’t think about updating another program in Outlook. TECHNIPAGES ROCKS!

  10. Hi, thank you for the info provided. Unfortunately I follow each of the steps indicated, I go through the wizard to update Microsoft Applications (I tried with all of them) but what I am told is that there are no updates available at this time. Where am I wrong?

    I also updated and restarted the whole Mac but nothing, Microsoft Outlook still doesn’t work.

    Cheers

  11. I did update office 365 E5 word, excel and ppt and have macOS High Sierra. Didn’t get work on it

  15. I followed suggested steps and downloaded and installed AutoUpdate, and everything worked! Thank you so much!

  19. It worked!!!! in my experience, I opened word, excel and power point.. I was able to do the update from word, and basically the update window showed that all the microsoft applications required upgrade.. in the first attempt and chose all of them (like 3gbs) and it didnt work.. so i started over but in the second opportunity I only chose Outlook (like 900mb) and it worked smoothly!!!

  20. Simply BRILLIANT!!!!!!! So THANK YOU! Didn’t need to call the IT people and look stupid. lol

  21. Brilliant, what a lifesaver!
    Updated without any hitches and opened up with all my folders intact.
    Where there’s a will, there’s always a hack.
    Thank you, thank you, thank you!

  28. HI can anyone help? I updated my Microsoft for Mac today for outlook. word. powerpoint etc. on upgrading to outlook version 15.41 but on updating I have opened, and found I have now lost all my personal folders.

    I tried exporting a back from olm file (which I did before this backing up) and that hasn’t found my folders.
    My entire life is those folders.
    Please can someone advise?

  29. After the High Sierra upgrade I got the compatibility error on my MBP. Completely reinstalled Office from the MS Online portal. Everything is fine except Outlook. Takes hours to sync simple messages. It’s not my server because Outlook on Android is working perfect on the same internet connection.

  30. High Sierra seems to be forcing an expensive update to my old trusted excel.
    How frustrating is this sort of nonsense.

    I can’t even make some simple changes to a spreadsheet recording many years of transcactions without my mac saying it cannot save the changes.

    Please help me while I still have some hair to pull out !!!

  31. So frustrated and overwhelmed.. Bought a new expensive Mac running High Sierra. Absolutely nothing works. None of my software: photo apps, Microsoft apps, Adobe, Mail, no scanner for the printer-simply nothing. Just feel sick. Managed to download Firefox for a puzzle game. So I have a $2700 beautiful computer but trapped into using my 8 year old iMac and getting mail on my phone. Wasn’t expecting this.

  32. Doesn’t work for Outlook 15.21.1. Is it best to get rid of High Sierra and how do I do this? I need my old outlook back!!

  33. Did the update and problem persists in Outlook. Specific problem is printing an email from OUTLOOK on a HP 4000 Laserjet. I get the following message and data

    ERROR: MemoryFull
    OFFENDING COMMAND: xshow
    STACK:
    followed by 6 rows of numbers

    Printing of Outlook Attachments works fine. Printing from Word, Excel and Powerpoint is fine. ???????????

  38. Same issue here. I’m on Outlook 15.19.1 and when I go to Word and Excel they both say that no updates are available. What am I missing? At this moment my e-mail is dead, I presume, because of my upgrade to High Sierra.

  40. Hello Mitch,

    I’m using version 15.28 and there is no “Check for updates” in Word. Word is OK but I cannot open Outlook where all my passwords are stored :-(

Did this help? Let us know!
