Read time: 12 minutes

As Microsoft 365 offers excellent features and functionalities, it has gained a remarkable position in the market by means of a collaboration and productivity platform. Many organizations acquire advantages from offered services as the Office 365 platform is extremely secure for data too. It helps users store and edit enterprise-level data and allows them to share and collaborate with others via advanced collaboration tools and applications, irrespective of their geographical locations.

Microsoft 365 has always encouraged businesses to migrate to the cloud since its launch in 2011. Though it provides multiple subscription plans, affordable pricing, and a set of applications for communication and collaboration purposes, Microsoft 365 still lacks some points. There are some common problems that many Microsoft 365 users often face while using its services.

This article highlights some of the known Microsoft 365 issues and their solutions that users often encounter.

Sign-in problems with Microsoft 365 – Sometimes users are unable to sign into Microsoft 365 portal; there could be two reasons behind the specific problem – either the incorrect password or service that handles log-ins is not supportive. You need not worry about this as it can fix easily.
Most users might know that Microsoft 365 Home and Personal license rely on your Microsoft account. Hence, your Microsoft 365 ID and password must match your Microsoft 365 account. Make sure you input the correct credentials for your account. You must check that the CAPS LOCK key is not turned on while inputting the password. It might be possible that an administrator changed your password or deactivated it. If it happens, you need to contact the administrator to resolve this problem.

In case the problem still persists, click the Can’t access your account link on the Microsoft 365 log-in portal. The password reset guide will help you how to verify and change your password. To recover work or school accounts, you can use this link: https://passwordreset.microsoftonline.com/

While configuring your account, it is quite important to set a recovery email address for recovering the account easily, even if it has been locked. You need to fill out the account recovery form in case your account has been locked, which doesn’t include any recovery email address.
Synchronization errors with Microsoft 365 – First, let us explain what the synchronization problem is. When you open any Microsoft 365 application like Word, Excel, or PowerPoint, recently added files must appear in every application. But if it doesn’t appear, there are chances of synchronization problems with your Microsoft 365 application.
Well, it’s infrequent with the desktop version; mobile users often face this problem. In such cases, you should close the app immediately and re-open it. If the same problem still occurs, several reasons, such as using an older application version and interrupted internet connection, may be responsible. However, installing the updates may not always be the appropriate solution to resolve synchronization problems, especially for the Outlook application. Many users have complaint that their application crashed after installing KB2837618 or KB2837643 updates. To fix this issue, you must uninstall these updates by following the below steps:
- Open the Control panel in your system and click Programs and Features.
- Select KB2837618 and click Remove.
- Select KB2837643 and click Remove.
- Finally, restart Windows and run your Outlook application again. Check whether everything is working properly.
Difficulty in getting support – When we take any service or plan, we expect hundred percent technical support from the vendor. But, with Microsoft 365, users don’t get satisfying support from their team. We don’t mean that Microsoft doesn’t provide any assistance, but it doesn’t facilitate any support system to deal with every support request. Hence, if you have a query related to Microsoft 365, you’ll have to wait for some days to get an efficient solution.
The only other solution that you can use is to get help from an external IT support service provider or use a third-party tool to fix your issues.
Bandwidth demand – High bandwidth demand for Microsoft 365 often becomes the most challenging thing for users. While working online with Microsoft 365, users need sufficient bandwidth to maintain the workflow, especially while managing many files in OneDrive. One way to clear out this situation is by contacting your internet provider and asking for higher bandwidth plans.
Microsoft 365 isn’t 100% cloud-based – Most of you know Microsoft 365 as a 100% cloud-based platform, but some apps of Microsoft 365 are not available in the cloud like MS Access and Publisher. Now, it is up to your bandwidth, which type of Office apps you use – desktop or cloud. Because businesses with lower bandwidth will end up using the desktop version of Office apps.
It is not easy to migrate to Microsoft 365 – Almost all Office 365 issues can resolve quickly but migrating to Microsoft 365 is one of the worst nightmares for users. While performing the migration to or from Microsoft 365, users face a lot of difficulties, such as:
- Migrating all types of data- Exchange data, SharePoint data, OneDrive data, IMAP data, etc.
- Difficulty in performing the migration using manual methods
- Requirement for technical experts for migration
- Need for selective migration
- Ambiguity is estimating migration time and feasibility
- Finding a good professional Office 365 Migration tool.
- Assigning impersonation rights to users mailboxes
With these obstacles, it is almost impossible for non-technical users to perform the migration in Microsoft 365.
