Issue with adding new users to Quickbooks online

Thanks for joining the Community and getting involved with this thread, jczar.

To verify my understanding, what error message is your new user encountering when trying to accept their invitation? If you could provide a screenshot showing what they're seeing, that'd help me to better understand the situation.

If they're encountering a "The feature you've requested is temporarily unavailable" message, there's a resolved investigation (INV-94406) about it. This means it's been fixed by Intuit's Product Investigations team.

In the event your new users are still encountering the message while trying to accept their invites, I'd initially recommend having them check their browsers. It's possible this could have something to do with temporary internet files. Browsing applications store these types of records, but sometimes they can cause issues with certain webpages. They can open a private window and check to see if the message displays while trying to accept their invitation.

Here's how to access incognito mode in some of the most commonly used web browsers:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Option + P

If the message continues displaying while browsing privately, it's safe to say this problem's being caused by their browser. It can be fixed by clearing cached data and Intuit-specific cookies.

In the event it continues showing the message while browsing in incognito mode, they'll want to try switching to another browsing application.

Here's a list of supported browsers:

• Google Chrome - version 78 or newer
• Mozilla Firefox - version 76 or newer
• Microsoft Edge - version 75 or newer
• Opera - version 68 or newer
• Samsung - version 10 or newer
• Safari - version 12 or newer

QuickBooks supports the current and two previous versions of browsers. If you find that a new user trying to accept an invitation is using an unsupported version, make sure to have them update it to its latest release. Steps for doing so can be found on the particular company's website.

In the event they've found no problems that could be causing this with their browser, they'll want to check their operating system and internet speed.

Here's our recommended operating systems and internet speeds:

• Windows PC - Windows 10, Intel Core i3 or a comparable processor (2013 or newer) with at least 2 GB of RAM, or Windows 10, Intel Core i5 or comparable processor with at least 4 GB of RAM.
• Mac - OS X El Capitan 10.11, OS X High Sierra 10.13, or newer.
• Linux - QuickBooks works with Linux, but you'll want to make sure you're using a supported browser and our recommended internet speeds.
• Internet connection - 1.5 Mbps to 3 Mbps or higher.

If they meet our system requirements, but are still encountering the message when trying to accept their invitation, I'd recommend having them try using a different device and/or internet connection. If it continues happening on other devices and internet connections, you'll want to get in touch with our Customer Care team and reference the investigation's case number (INV-94406). They'll be able to pull up your account in a secure environment and conduct further research with you.

Detailed steps for reaching them can be found in Clark_B's post. Be sure to review their support hours so you'll know when agents are available.

I've also included a detailed resource about system requirements for QuickBooks which may come in handy moving forward: System requirements
