Latest message:Title: Outlook client connectivity issues
User Impact: Users may be unable to connect to the Exchange Online service when using the Outlook client.
More info: This issue only affects users with multiple Exchange Online accounts. Affected users will see the Outlook desktop client showing as disconnected and may receive the following error when attempting to send mail: "Sending and receiving reported error (0x80040115). The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action."
Users may be able to take advantage of the following options to circumvent impact for this event:
- As this issue only occurs in the Outlook desktop client, the simplest way to prevent further impact, where possible, is to rely on Outlook on the Web or the Outlook Mobile client to access Exchange Online services.
- Users unable to rely on access via alternative Outlook clients may be able to restore their Outlook desktop client email access by signing out of all office apps and then back in:
1) Close Outlook and other Office applications.
2) Open an Office desktop application, such as Word, PowerPoint or Excel.
3) Navigate to File > Account > Switch accounts, and then click the ellipsis next to the account that's not having the problem.
4) Click Sign out and then OK.
*Note: Users that have multiple accounts may find it difficult to determine which account to sign out of; though, they should be able to sign back in later if there is an issue with this process.
5) Close the Office application used for this process and re-start the Outlook desktop client.
6) When prompted for a password, click "sign in to a different account" and enter the correct information.
- Lastly, affected users who are unable to perform either of the above actions may be able to use the link below for instructions on creating a new Outlook profile, which will allow the user to regain access.
