Proposal: Have the option through GUI to disable automapping for inboxes, and/or certain individuals that have permission to that inbox.

Explanation: When you assign permissions for someone to a particular inbox (including shared) it automatically adds the mailbox to their Outlook profile - this has caused us issues. While it can be disabled through PowerShell, it's very tedious to go through and remove each user and then add each user to every inbox with automapping disabled.

Phishing emails are on the rise where Sender's name is used to lure recipients into trusting spam. We would like to prepend a disclaimer for emails originating outside the domain and add the sender's real email address to it. We have programmed the disclaimer but have been told by Microsoft tech. support that it is by design that sender's info is not available to be added to disclaimers.

In case the big file is deleted (i.e. 1TB) from all recycle bins, it still takes this much space in the Preservation Hold Library folder. It would be great to be able to delete such file/folder at least by Global Admin. Otherwise, when the Retention Policy is set up for several years or never delete, even if the file is deleted there might be no room for the new files on user's OneDrive.

The Report Message Add-In can be deployed centrally but there should be a method to control the settings/preferences in it centrally. For example, set the default option for reporting preference (e.g. always send, never send, ask every time). This should be configurable somewhere (e.g. registry key, GPO, Centralized Deployment manager, Exchange Online policy, etc. The default to ask every time is not the setting we want for our organization, but there is no way currently to reconfigure the default. Please reconsider this.

It would be great if we could change the initials in the colored circle on outlook. I am able to change it on word, excel, etc. so it would be awesome to do this on outlook too.

Any steps to transfer the ownership of files and folder from OneDrive account to another?
Your competitor can do it, but OneDrive... NO

We planned to migrate from Dropbox to a SharePoint document library and when implemented, we immediately hit the 5000 item limit in a library. This is ridiculous in 2018. We have used folders with over 35,000 files on Dropbox without any issues. This is an unfortunate limit for a product that is called Office365 for business.

Please increase this limit or provide another means to load and backup large datasets.

Allow the creation of new remote mailboxes that are 'shared' mailboxes. At present, you have to create a regular user mailbox and then after you have synchronized this to Office 365, you then have to login to the 365 admin portal and convert it to shared. The problem with this method is that the user object on premises will always be shown as an office 365 mailbox and not an office 365 shared mailbox. Just a bit messy.

It seems impossible to create a DDL based on the domain name, because the recipient filter does not accept wildcard at first position in the -like condition.

Bring back the ability to have custom domains on O365 Home Premium. I have a family domain and want to set it up as a domain on my O365 account.

within settings ---> dirsync errors, there is no way to clear out old errors that have been resolved. We also get weekly emails saying we have dirsync errors in which we do not have any current ones, rather it is a summary of old errors we have that makes us think we have current synchronization errors. This has came up on a support posting: https://answers.microsoft.com/en-us/msoffice/forum/msofficeo365admin-msoother-mso_o365b/how-to-clear-dirsync-error-report/97b43be7-5155-4a75-b69e-9782efdd161b

please add a way to clear out old errors from this dashboard.

Currently, the Email Activity Report only presents data for user mailboxes. Expanding this report so that it could include shared mailbox types would be great, as we use shared mailboxes for "contact us" and "support@" mailboxes for may of our customers. Being able to show email volume for these mailboxes over specific date / time ranges would be a great help!

Over the last month or so case sensitive searches have been added into the shared mailbox and permissions sections on the Office 365 admin page. Could these be reverted back or was there a reason for case sensitive searches being added?

I had weeks of no results coming back until I spoke to Microsoft Support who also have the issue and they noticed it is now case sensitive.

Currently our SharePoint uses tenant.sharepoint.com but I would ideally like this to be changed to intranet.mydomain.com or extranet.mydomain.com. It seems I can't use my vanity domain name for a SharePoint site or have multiple top level sites such as intranet and extranet for different purposes.

Highly needed Email Signature management option with signature directly under the latest email reply or forward

RSS feed for Service Health Dashboard is not available anymore.
Now User can get service health notifications from the Office 365 Admin mobile app.

But the previous RSS feed was also fruitful service since User can download it by Outlook Client.
Re-release RSS feed for Service Health Dashboard will be an ideal feature for many Users.

This feedback is based on a customer voice from support SR.
