Hello JP, I dont know how outlook app interacts with FF, unless you are talking about the online outlook service, aka Outlook on the Web.

As you can see from the pic, i have no issues logging into Outlook on the Web. So there is likely something that you have installed either in FF or Windows that is blocking your access.

Perhaps, one of the apps needs to be updated to recognize the newest version of FF. So you could try to figure out which app may be problematic by temporarily disabling all FF addons and Windows Start Ups. Then reboot and retest the site.

If the site does work after the above, then enable one app and or startup, then reboot and retry the site again. Do this for all those apps you had disabled, Eventually you will find the one app that is causing you some grief.

Also as a thought, uninstalling the newest version of FF may not be an ideal solution unless you have taken the extra precautions of preserving your bookmarks and pw's.

So instead, you may first want to install an older version of FF that was functional for you and its own unique folder. Then later ensure that your bookmarks and pw's have transferred over safely and you have turned off the auto updating feature in the older FF.

I am using outlook desktop 2016 not an app. I don't know how to remove the latest foxfire download. Everything was fine until I downloaded the Foxfire 88 update. Can you please advise me how to remove the most recent update?

Oh, you mean MSOffice 2016 Outlook Module.

It is unclear why FF would interfere with Outlook.

Just some fyi, your outlook contacts should be synced to the online outlook version.

While i think its best to tweak your system and ensure that everything is in balance, you can remove FF via the "Apps" section in Win10.

Windows Start Button > Search > remove app > then from the searh results pick the appropriate action.

The alternatives to uninstall FF are:

You can also restore the previous version of FF by looking at the "properties" section of the icon and gong to the tab pertaining to versions.

You should also be able to repair your MS Office 2016.

In any case, be sure to copy your bookmarks and pw's from FF, in case you need them in the future.
