Description of the issue:

Since yesterday, I can’t access Outlook anymore and receive the 403 Forbidden
Microsoft-Azure-Application-Gateway/v2 message. Nothing changed on my end: still working on MacOS, no VPN, no changes to internet. I cleared cookies browser history restarted etc but this goes above my paygrade. How do I get back on Outlook web?

Please edit your Original Post (“OP”) above, in order to include:

  • Brave Browser version numbers
  • Operating System version numbers

In Brave Browser Settings, DISABLE ALL extensions added by the user. “ALL” means all of them, added by the user ← who sometimes will cling to some extensions, and thus fail to properly test the issue.

Restart Brave Browser. Test.

Install each extension - alone, no combinations of extensions. Test.

You may find one extension is a cause, or, after having tested each extension alone . . . then testing combinations, a combination of extensions is the cause, or the order of installation that you have had - was the cause.

My own opinion, is that any anti-virus extension should be installed last, and any adblocking -type extension, should be BEFORE that last anti-virus extension.

You might test, by creating a new Brave Browser Profile:

  1. Create a fresh browser profile (Menu --> More tools --> Add profile)
  2. Close your original profile windows (so you only have the new profile window open)

In a Brave Browser New Window, go to the On exit tab at:

  • brave://settings/clearBrowserData

Disable: Site and Shields Settings ← so you do not lose Site and Global Shields settings. (Global Shields settings: brave://settings/shields)

Save that work.

And, in order to increase the chance of success:

In a Brave Browser New Window, go to, one-at-a-time, each of the following brave://settings/content/siteDetails pages:

  • brave://settings/content/siteDetails?site=https%3A%2F%2Fcloud.microsoft
  • brave://settings/content/siteDetails?site=https%3A%2F%2Fhotmail.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Flive.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Flogin.live.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Fmicrosoft.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Fmicrosoft.net
  • brave://settings/content/siteDetails?site=https%3A%2F%2Fmsn.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Foffice.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Foffice.net
  • brave://settings/content/siteDetails?site=https%3A%2F%2Foutlook.com

At each of those Brave Browser Settings pages, scroll down to JavaScript and set the selection manually to Allow

Those steps, are a relatively fast way to Allow JavaScripts from Microsoft servers.

Exit / Quit Brave Browser. Restart the computer.

Tips regarding Brave Shields:

I have more success, with:

  • Brave Shields UP
  • Either Allow All Cookies or Block 3rd Party Cookies, but NOT Blocking All Cookies
  • Allowing JavaScripts from specific sources, but NOT Allowing All JavaScripts
  • Trackers & Ads treatment: Aggressive (at first), and then incrementally relaxing that setting
  • Fingerprinting (aka footprinting) blocking: Strict (at first), and then incrementally relaxing that setting

I almost NEVER use:

  • All of Brave Shields UP
  • All of Brave Shields DOWN

Creating a new profile seems to have worked for now! Thank you. Apologies, my Brave browser was the most up to date and I’m working on OS 15.3.2

So “a new profile seems to have worked for now” . . .

I would use the Brave Browser Settings of the new profile - take screenshots - to compare with the Brave Browser Settings of the old profile.

Of course, for the old profile, in a Brave Browser New Window, go to the Advanced tab at:

  • brave://settings/clearBrowserData

Time range: All time

ENABLE:

  • Browsing history
  • Download history
  • Cookies and other site data
  • Cached images and files

Click Clear data

Exit / Quit everything. Restart the Mac.

In other words, for the old profile, clean house as much as you can.

Please establish a routine for data backup.

Where Brave Browser has usually been installed on the Mac:

/Applications/Brave Browser.app

/Users/username/Library/Application Support/BraveSoftware/

The initial Brave Browser Profile is, by default, named “Profile 1” (unless you change that name → brave://settings/getStarted).

The folder that contains the initial Brave Browser Profile, is the Default folder (a name that you must not change):

/Users/username/Library/Application Support/BraveSoftware/Brave-Browser/Default

If you create 1 additional Profile (aka “Profile 2”), it will be stored in folder Profile 1:

/Users/username/Library/Application Support/BraveSoftware/Brave-Browser/Profile 1

If you create another additional Profile (aka “Profile 3”), it will be stored in folder Profile 2:

/Users/username/Library/Application Support/BraveSoftware/Brave-Browser/Profile 2

AGAIN, IF you have not changed the Brave Browser user Profile names, THEN:

Profile named “Profile 1” data is in folder named “Default”

Profile named “Profile 2” data is in folder named “Profile 1”

Profile named “Profile 3” data is in folder named “Profile 2”

etc.

That pattern applies to all Brave Browser Linux OS, MacOS, and Windows OS users.

/Users/username/Library/Application Support/CrashReporter/Brave Browser ... .plist

/Users/username/Library/BraveSoftware/

/Users/username/Library/Caches/BraveSoftware/

/Users/username/Library/Caches/com.brave.Browser/

/Users/username/Library/Logs/DiagnosticReports/Brave Browser ... .crash

/Users/username/Library/Preferences/com.brave.Browser.plist

/Users/username/Library/Saved Application State/com.brave.Browser.savedState/

And the “Brave Browser … .diag” reports within:

/Library/Logs/DiagnosticReports/

You might not find:

/Users/username/Library/BraveSoftware

. . . do not worry about that.

Be Prepared

On the Mac, I use a combination of bash shell and AppleScript scripts, in order to daily backup the BraveSoftware folder at:

/Users/username/Library/Application Support/BraveSoftware

The script(s) make a .zip compression of that folder, and then name the folder with a chronological name; examples:

  • 20250403_BBSftWr_BKUP.zip
  • 20250404_BBSftWr_BKUP.zip
  • 20250405_BBSftWr_BKUP.zip

. . . and those files are stored safely out of the way, of the Brave Browser installation paths. Also stored, on external drives.

When I encounter some problems, I exit / quit Brave Browser. Swap out the current BraveSoftware folder at:

/Users/username/Library/Application Support/BraveSoftware

Replacing with the recent backup that I made.

Takes less than 1 minute. Problem solved at a much, much greater speed and efficiency . . . because I back up my data. Every day.

In your case (403 issue), I would have done that, swapped out the BraveSoftware folder for the recent backup that was made 3 days ago.

Or, I could swap out the Default folder or another Profile folder.

But I most often, swap out the BraveSoftware folder.
