Outlook Android “Sync Contacts” disabled for Microsoft 365 Business Standard tenant
I am the Microsoft 365 tenant administrator. Outlook and Authenticator work correctly on Android. The “Sync Contacts” toggle inside Outlook is disabled/greyed out. Native Exchange setup hangs on “Retrieving account information”. No Intune license available (Business Standard tenant). How can I enable Outlook contact synchronization with Android Contacts?
Outlook delegated inbox
We have 10 users all have newer Dell windows 16gb 256gb at least laptops all users use classic outlook at the moment. they all use two monitors with the laptop They are all currently in three inboxes one inbox for order inquires, one inbox for orders which is delegated and the one we have issues with and there personal inbox. They like to use a inbox as a work queue users find the email they want to work on forward it to there personal email and move the email out of the queue inbox. While using the queue inbox as an archive. Everyone has cache turned off nothing is downloaded locally for the shared inbox. We originally had each user on the team sign into the inbox with the same credentials not best practice but this team started with two people and quickly grew. We now have users delegated to the inbox we run into several issues. The outlook drags with everyone in the inbox The outlook does not keep kept up say someone deletes an email someone sitting right next to that person would still see the deleted email in the shared inbox. Causing duplicated works Delegated inbox moves deleted items to users personal inbox same with sent items. Analytics and reporting and archiving is a whole other issue but not what I am honestly looking for help with. MSP wants to get users on a mail handler but the team does not want to have another tab open even when an extra monitor was offered. They also do not like the idea of going back in forth between two different inbox systems. " we basically will have two outlooks" Team wants something light weight even asked if there was some sort of extension for outlook. Storage wise it has a 50gb storage with an online archive archiving takes place every 3 months. the storage stays at 60-80% if it hits 90% or over the inbox is almost not functional. We thought storage and usability corelated but today we had issues at 70% continually. I know i sound green please be as brutal as needed my pride is less important than this issue. In the off chance someone has been in a similar issue would appreciate any insight on how they navigated it and really wanting to learn.
Forgotten email password request being seen coming from a different email account
When at http://account.microsoft.com/ to reset a forgotten password for a Microsoft Exchange account with a registered domain email account the code being sent is being seen as a forgotten password reset request for my http://hotmail.com/ email address. Why is that and how can I have my forgotten password request be seen coming from my domain email account?Synchronization issue in New Outlook for Mac – ״Failed to refresh subscriptions.״
Hello, I am using Microsoft 365 (Exchange Online) on Mac, running macOS 26.1 (Tahoe). My Outlook client is: Outlook for Mac Version 16.103.3 (25113013), with a Microsoft 365 Subscription license. Since yesterday morning, in the New Outlook interface, my inbox has suddenly appeared empty, and I constantly receive the following error message: “Failed to refresh subscriptions.” It’s important to note: In Legacy Outlook, everything works perfectly. The web version and the Outlook app on my mobile phone also work well. The issue persists regardless of the network I am on (home, office, cellular, etc.). Troubleshooting steps I already tried: • Updating Outlook to the latest version • Removing and re‑adding the account • Clearing cache and preferences • Formatting my Mac and reinstalling everything from scratch Unfortunately, none of these steps has resolved the issue. Is this a known bug, and is there a recommended workaround or an upcoming fix? Appreciate assistance on that issue.
Exchange Online: Sudden mass quarantine of legitimate emails (tenant‑wide impact)
Hello, Since last Thursday , we have been experiencing a sudden and significant increase in quarantined emails across our Exchange Online tenant. Key observations: - Hundreds of legitimate emails are being quarantined every day - The issue appears tenant‑wide and affects multiple senders and recipients - No recent configuration changes were made (Exchange mail flow rules, Defender for Office 365 policies, or security presets) - Messages are being classified as spam/phish even though they are clearly legitimate - Manual release is currently required, which is operationally unsustainable and error‑prone - Business‑critical communications are being delayed or missed as a result We have an active Microsoft support case open, but the root cause is still unclear. I would like to ask the community: - Are other Exchange Online tenants seeing a similar spike in quarantined legitimate emails since last week? - Has Microsoft acknowledged any backend or filtering model changes or service issues related to quarantine or Defender for Office 365? Any confirmation or shared experiences would be greatly appreciated, as we are trying to determine whether this is an isolated tenant issue or a broader service‑related problem. Thank you.
Add-in without Connected Experience
I've developed an Outlook Add-in using the new web tech based approach (not a legacy COM Plugin). One of our customers wants to use said Add-in, but they have the requirement that they can't enable the "Connected Experience" for their Outlook. Is it possible in any way to use an Outlook Add-in without having to enable the "Connected Experience" or is this just not an option?Increasing Microsoft Graph Per-Mailbox Throttling Limits (PUT/POST/PATCH & Concurrency)
I am referring to the per-mailbox throttling limits documented here: https://learn.microsoft.com/en-us/graph/throttling-limits#limits-per-mailbox Specifically: 150 MB limit for PUT/POST/PATCH requests within a 5-minute window 4 concurrent requests per mailbox In a multi-tenant SaaS application scenario, these limits can become restrictive when processing large volumes of mailbox data. I would like clarification on the following: Is it possible to request an increase in these per-mailbox limits through Microsoft (e.g., via support or a formal quota increase request)? Are there recommended architectural patterns or best practices to efficiently handle high-throughput scenarios while staying within these limits? Can tenant administrators (our customers) configure or influence these limits through Microsoft 365 admin settings? Any official guidance or recommendations would be highly appreciatedClassic Outlook: The People Card Is Not Retiring, Just the Expanded View
One part of this Classic Outlook update could easily confuse people, so it is worth clearing up. In June 2026, Microsoft is retiring the People Card Expanded View in Classic Outlook. The full People Card is not going away. Users will still be able to open the standard contact card. What is changing is the expanded view, which gives users a little more context and a few extra details in one place. It may seem like a small change at first, but these types of updates can still affect how users look up contact information and move through their daily work. I put together a full blog post that explains what is changing, what stays, and where users can still get the richer contact experience.
