Also, at the time, that user did not have MFA turned on. In the instances that this occurs the effected user is not new to MFA but has been running it for at least months. The problem appears to randomly affect users (I’ve had it affect myself once too), and the only solution appears to one of (or a combination of) the options in the OP. Out of 140 staff the problem seems to occur once every 2-3 weeks on average.

The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action. Create your account and connect with a world of communities.

Microsoft Office 365 Endless Authentication Loop Issue
Native IOS and Android Mail apps will require the APP password or users can use Outlook for IOS/Android which is Modern Auth aware.There doesn’t appear to be any pattern to the issue occurring or the problem being limited to any specific computer or user.I checked my MS account info page, subscription is fine.When we opened the old, existing profile it didn’t ask for ANY authentication, it just started working.The user could use the Windows mail and calendar apps but Outlook wouldn’t connect and kept prompting for a password.I disabled the Zoom and Adobe PDF plugins and it stopped prompting me immediately.

Outlook stuck in an MFA loop
Close and open your web browser again and go into [Microsoft Outlook Email Repair Tool Online](https://body-positivity.org/groups/turn-on-cached-exchange-mode/) SuiteFiles. You will most likely need to enter your Microsoft 365 credentials again so ensure you tick any box that says remember my credentials but it should now work for all future documents you open and not require your credentials. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. I regret that you are experiencing issues with your Microsoft installation.
Outlook 365 Password Prompt Issue on Windows Desktop
So not doing anything at all even seems to work. Which to me sounds [Outlook sync help from FixTechGuide](https://phantom.everburninglight.org/archbbs/viewtopic.php?id=146436) like the issue is service side, not client side. Problem doesn’t just happen on PC’s connected to the internal network, but can happen when a laptop is remote and connected via external wifi or mobile hotspot.
