I log in. I am asked for a mobile number so I can verify account changes and reset my password. I find my mobile number listed on my contact card. I remove my mobile number. I log in.

I want the semi-two-factor auth this provides, but the last thing I need is to have my entire company contacting me for support after hours or for vendors or clients, with access to our address book, contacting my cell... EVER.
I have seen numerous others on various forums asking for the same thing.

Office 365 Groups (aka: "unified-groups") are becoming the "standard" share target in Office 365. You can share SharePoint content (files, list items, etc.) with an O365 Group. You can share Microsoft Stream content with an O365 Group. You can share a Flow with an O365 Group. You CANNOT, however, share a PowerApp with an O365 Group. This is a huge issue and greatly complicates our job of "selling" PowerApps as a solution.

For example, we've successfully convinced a LOT of our client groups that an O365 Group is a better solution than "just" a SharePoint site (most of these had sites/site collections in our SP2010 environment). Many of them latched onto Teams as well, and by an large, they've been off & running. Then, they want to build a PowerApp to make it easier for their people to enter or update data. Sure, they can build the app, and since the data is coming from the Team's (or Group's) SharePoint site, permissions is not a problem. However, the Team/Group members cannot actually RUN the PowerApp until it's been shared with them. Since PowerApps only allows sharing with individual users or AD security groups (NOT O365 Groups), they need to either share it with each Team/Group member individually OR they need to have IT create an AD security group and populate it with the Team/Group members. On top of that, as people in the Team/Group change, the owner of the App needs to then update the sharing or have IT update the AD security group. This goes exactly against the concept of Office 365 giving users an easy and coordinated way to manage their Teams/Groups and the apps and services provisioned to them.

People in the world, both admins and users, are constantly asking whether new features Microsoft has announced as on the way or rolling out are deployed to their tenant yet. This often results in a lot of confusion and probably support cases and questions into Microsoft asking these types of questions.

We could solve this by building some sort of "Is this feature deployed to my tenant yet?" tool. This tool would very simply authenticate the person checking via Azure Active Directory, and then return a simple result for the feature you are checking on. Results could be:

• Yes


• Targeted Release Only


• No

It would also be nice if IT Admins could provide a small bit of text/guidance for users in case they come across a feature where the answer is Yes, but the user does not have access. This could point them towards some sort of Support function, request process, etc so IT has a better idea of the needs of their users.

Currently you can purge all contents of a user mailbox by using the following commands:

Search-Mailbox -Identity "identity" -DeleteContent -force
Search-mailbox -identity "identity" -SearchDumpsterOnly -DeleteContent

This wipes the user mailbox completely without removing the mailbox itself. There currently is not a way to refine and delete content for specific mailbox or custom folder names while leaving content from other folders in the mailbox alone. Example: Purge only: Junk Email, Deleted Items, Clutter, Custom Folder 1, Custom Folder 2, etc.

Search-Mailbox not working

"We cannot identity the specific folder to search. To delete the message in the specific folder, retention policy is a better choice.

The TargetMailbox parameter specifies the identity of the destination mailbox where search results are copied.

The TargetFolder parameter specifies a folder name in which search results are saved in the target mailbox. The folder is created in the target mailbox upon execution.

Since you are going to delete these messages, then use DeleteContent cmdlet. If you want to copies these messages for backup, then you add TargetMailbox parameter with TargetFolder. If you don't want these messages anymore, then just add DeleteContent parameter.

Search-mailbox -identity "AUser" -searchquery {Received:"31/10/2015"} -DeleteContent"

We need a feature to be able to turn off certain notifications to our alternate email address in Office 365.

As Office 365 administrators, we are require an alternate email address that is not part of your Office 365 tenant. In most cases that would be your personal email address that is not provided by your work. This makes sense for password resets if administrators forget their password to log into the tenant.

Along with password resets, we also receive Office 365 statements, changes to tenant subscriptions and other notifications. These should have an option to turn off since all of these are company work related. It does not make sense that work notifications are required to be sent to alternate personal email addresses of administrators. Business emails should stay with business email addresses, not personal email addresses.
