Welcome to the forum.
The community would like to help but can you clarify few item for us?
1. How are you accessing your email?
- Are you using an email client or Outlook Web Access via MyAccount portal?
2. How does your colleagues access the email?
3. When did this issue started?
I fiddled ( have no idea how I got them running - just plahing around with them) with the accounts yesterday afternoon and now only 3 have no access - they are two newer accounts that we access through comcast.biz.net and one older email through comcast. I was able to get 3 working.
This began after the update ( the next morning the access was not there) they are receiving several different messages but the consistant one reads the following:
Outlook Web Access could not find a mail box then HMC1 and the email address is listed.... We don't have on site IT support they would have to come from about 4 hours away to access the server. All the email addresses are active when I go into comcast.
I sent test emails from my computer yesterday, they did no come back to me and when I was able to fix 3 of the email addresses the test emails I sent to them were in their boxes.
I am going over to the main facility and try again this a.m. to see if I can work on them.
Thank you for the update and information.
Sounds you are trying to access the OWA using a shortcut link.
I would suggest to access them through the "MyAccount" portal.
Additionally for the email client setup.
Try setting up an user profile that is not working on a computer that is working for comparison test.
This will determine if the issue is with the account it self or the email client.
