Some people find that they still get popup reminders for some events even after they have deleted some events from their Outlook calendar, or even after removing the entire calendar. The problem occurs with deleted and canceled meetings in the Outlook desktop client when you have mailboxes hosted on the Exchange Server or Microsoft 365.
Outlook may prompt you to enter your Microsoft Account (Office 365) credentials when you try to create a new mail profile or open a configured mailbox. This happens in all modern Outlook 2021/2019/2016 and Outlook Microsoft 365 versions. The fact is that Direct Connect to Office 365 is enabled by default in Outlook. This feature is designed to simplify and speed up the process of connecting to a mailbox hosted on Microsoft 365 (Exchange Online).
In some cases, you may receive an error when you try to configure a connection to Exchange Server in Outlook Client for a new user, or when you try to connect to an Exchange mailbox server with a configured Outlook: the connection to Microsoft Exchange is unavailable. This article will show you how to troubleshoot and fix this error.
When you select an Exchange distribution group as a recipient in Outlook, you should see a
+ sign to the right of the group’s display name. If you click on it, you’ll expand the distribution group and see a list of its members.
By default, mailbox folder names in Outlook (
Contacts, etc.) correspond to the Outlook regional (language) settings of the computer where the mailbox was first connected. If you have Outlook with the French localization installed on your computer, all default Outlook folders will be named in French.
