Windows Outlook Authentication error when I try to log into Bell Sympatico Email

[MonteCassino]

I have an issue that occurs every few weeks - yesterday (August 4 2026) was the most recent occurrence.  When I try to access my Sympatico.ca mail on Windows Microsoft Outlook, I get a message that "Access is Denied" and requests that I login using my password.  When I enter my password, Outlook seems to be trying to add the account but then it tells me that the sign-in failed.  This problem occurs at the same time on both my laptop and desktop computers, both running Microsoft Outlook.  Normally this issue last for one or two days and then it seems to correct itself and things go back to normal until it happens again.  I have no problem accessing my Bell Sympatico email via my Smartphone or through the Bell Webmail site (my password is accepted).  Also, Microsoft Outlook has no problem at all accessing my Gmail account - only my Sympatico account.  Does anyone have a suggestion as to what is causing this very annoying problem?  Many thanks!!

Hey there @MonteCassino 

Thanks for your post and welcome to the Bell community 🙂

That is certainly strange, especially since Bell Webmail continues to work and the issue only occurs periodically before resolving on its own.

Have you recently changed or updated your email password? When you log in are you using a a previously saved password, or do you have to enter it in manually?

The next time this happens, could you please capture a screenshot of the full Outlook error message, including any error codes or additional details that are displayed? That information may help us better identify the cause of the issue.

We are looking forward to your reply.

Many thanks for getting back to me...very much appreciated.

As usual, the problem which started earlier this week has now corrected itself, as usual.  My Sympatico account on Microsoft Outlook is now working fine.

When I access my Sympatico account on Microsoft Outlook, it is always using my saved password.  I never enter it manually.  I have had the same password for many years.  It has not been changed.

The next time this happens, I will do a screenshot of the Outlook error message and any other related error messages which appear.

This is certainly a frustrating problem...hope we can solve it!!
