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.

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.

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 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.

It would be very beneficial to have the Conversation View show sent emails in a shared mailbox. It appears that the conversation view does not show emails from sent or any other folders in the INBOX.

Actually it is not possible to obtain a free Exchange Server 2019 activation with a hybrid key. For earlier Exchange Versions this works trough HCW, but not with Exchange 2019: "Please note that HCW does not provide a 'hybrid key' for Exchange Server 2019. If you need a hybrid key, the latest version that it is available for is Exchange Server 2016."

This is not customer friendly at all - so please add Exchange 2019 to this feature.

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.

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.

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.

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!

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

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.

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.

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.

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

I would like to get an uptime graph for an specific tenant, instead of an uptime report for the whole datacenter.
Right now we can only get the Regional uptime graph and a tenant-level availability report will be much more helpful.

We want to be able to pull license expiry reports via other tools to keep our expiry reports consistent (IT Glue in this case). I can query many things by Office365 PowerShell module, including the license types, but I cannot query the dates in which these expire.
Why does this ability not exist? Can we get that exposed as part of the Office 365 powershell commandlets
