Microsoft Outlook 365 for Mac

I have Microsoft office 365 outlook, family subscription for Mac. Outlook is taking up over 50% of my memory. I followed the instructions to contact support through Outlook. I have an open order from when I WAS able to contact support through Outlook but it’s been 24 hours. I have three emails all seating into Outlook. One is set up through IMAP on my Mac and the other two are through Google/Gmail. For whatever reason, two of the emails are set up through IMAP on my desktop Mac while one is set up through Google/Gmail

The problem is, every time I try to go into Outlook to read the newest question or suggestion from Jijo, to fix my issue, outlook tells me I don’t have enough space and it kicks me off. I cannot do anything on my computer. I can’t delete messages to try free space, I can’t use the Internet, I can’t delete old emails

I restarted my computer and was able to get back to support long enough to tell him that it keeps kicking me out. He told me not to worry I can go back to the contact support tab under help and the ticket will be open. How am I supposed to check back to “customer support” when I’m unable to even keep Outlook open?

My head is about to explode. I just want outlook and all of the files related to it off of my Mac. I’ve always been a fan of Microsoft, but this is ridiculous. The fact that business subscribers are able to call a number and family/home subscribers are not is unexplainable to me. We are both paying for a service. I cannot afford to lose another day, waiting on a solution.

    Hi Renee Villaume,

    Thank you for reaching out to the Microsoft Q&A Forum!

    I truly understand how frustrating it is when Outlook for Mac uses so much memory that you can’t even keep it open, especially while trying to follow up with support. Please try the following steps carefully:

    1. Force quit Outlook

    • Press Command + Option + Esc, select Microsoft Outlook, and click Force Quit.

    2. Uninstall Outlook and its data

    If you want Outlook completely off your Mac:

    • Quit Outlook.
    • Go to Finder > Applications, drag Microsoft Outlook to Trash.
    • To remove its data, delete the profile folder: Go to Finder > Go > Go to Folder, navigate to ~/Library/Group Containers/UBF8T346G9.Office/Outlook and move it to Trash.
    • Empty Trash and restart your Mac.

    For more details, you can also follow this official guide: Uninstall Office for Mac - Microsoft Support

    3. Reinstall Outlook (Optional)

    If you still want to use Outlook after cleanup:

    • Open App Store > search for Microsoft Outlook > reinstall. Then sign back in with your Microsoft 365 Family account.

    You can see Download Microsoft 365 for Mac - Microsoft Support

    4. Contact Microsoft Support through browser

    If Outlook still crashes after reinstalling, please try contacting Microsoft Support again using a browser instead of the Outlook app via Contact - Microsoft Support. Look for and select "Chat with a support agent in your web browser" or a similar callback option then explain your situation clearly.

    You can also share your previous case/order number so they can locate your open ticket and continue helping you.

    I understand this has taken considerable time and effort already, I truly appreciate your patience and understanding. Please feel free to let me know how it goes. Take care.
