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 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.

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.

There should be option to provide external user access to shared mailbox.
Currently only internal user with license have access to shared mailbox. But there should be option such that external users can be added as member of shared mailbox created inside the organization since shared mailbox have feasibility to co-ordinate with external domain.

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/msoffice_o365admin-mso_other-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.

Please provide read only access feature for O365 Admin center

Provide centralized usage reports for entire SharePoint Online tenant such as page views, user sessions, usage per site collection, etc. Individual site collection reports are ok but are not centralized.

Allow renaming of initial domain. Would save a large amount of resources if the company did not have to setup and migrate to a new tenant organisation if the company name changed, eg for a merger/split.

This would make it easier for an administrator to know it the mobile is in the hand of a legitimate user before approval.

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

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!

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

Please publish the Exchange Online PowerShell Module used for MFA to the PowerShell Gallery (www.powershellgallery.com) to allow for easier installation.

The clickOnce installer is a bit of a non-standard installation for most people used to working with standard PowerShell modules.

Allow the portal log-in landing page to be changed for the entire organization as the administrator. For example, instead of being directed to Outlook, the user is directed to the share point site. I realize users can do this for themselves, but I'd like the ability to do it for them as the administrator.

Ability for app to be globally removed from the app launcher - as opposed to telling 50,000+ to unpin it themselves.

We currently have 3 different domains using 365 business premium and would like the bills emailed to us every month rather then having to log in and download the PDF statements/Invoices.

If its possible to add this feature it would be much appreciated

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.

I would like to have a Read only version of the tenant admin. This is great to give to security to do there audits as well as anyone doing there checks on settings for audit purposes.
Buy having this you dont need to give full tenant R/W access to staff that dont really need it or know what they are really doing. All the Get commands work but not the set commands..

We need a better way other than PAL for teachers to access student data in Office 365. The Share option is not a viable option when most schools have over 100 parents and needs to scale to 100,000s. If there was a parent SKU in which permissions could then be assigned to the student content, it would allow us as partners to develop solutions. We've been asking for 2 and half years and keep hearing, that's good feedback. Cheers

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.
